ABAP CDS Consumption Views are exposed as BW Queries and can be consumed by S/4 HANA Query Browser and BI Clients like Analysis for Office and Design Studio. With my BW background I was curious to put ABAP CDS Consumption Views to test and fulfill some of the typical BW Query requirements like:

  • Currency Translation
  • Display of Currencies and Units of Measure
  • Use of Attributes
  • Use of Texts
  • Use of Hierarchies
  • Use of Variables
  • Use of Calculated Key Figures
  • Use of Restricted Key Figures
  • Use of functions like NDIV0 and NODIM
  • Use of time dependent dimensions and hierarchies
  • Use of language dependent texts
  • Percentage Share calculation
  • Filtering Key Figures Structure
  • Setting Key Figure attributes like Number of Decimals
  • Setting Description (Variables, Characteristics, Key Figures, etc)
  • Setting Variable value dynamically
  • Defining Layout (rows, columns and free characteristics) and switching on hierarchy

So for my ultimate test I built my Flight Y2Y comparison ABAP CDS Consumption View from ground up starting from BASIC views to prepare data, then created TEXT, HIERARCHY, DIMENSION, FACT and CUBE view then finally built by CONSUMPTION view. I will not go much into details of implementation because all that you can explore on your own. What is more important is to understand ABAP CDS Consumption Views capabilities.

This is what I have got:

As you can see from screen shot above it is possible to create hierarchy (Region) and characteristic variables. Also parameters for currency conversion (Display Currency) and restricted key figures restrictions (Year 1 and Year 2).

As you  can see from screen shot above it is possible to do:

  • Convert currencies (dc e.g. display currency columns)
  • Create restricted columns (Year 1 and Year 2)
  • Create calculated columns (Seats Occupied %)
  • Activate hierarchy (region characteristic)
  • Display unit of measures (currency, quantity and % for formula)
  • Set number of decimal places (1 for Seats Occupied % columns)
  • Characteristics and Key Figures are given proper descriptive names

Lets see hierarchy node selection variable  in action

As you can see from above screen shot node variable filtered hierarchy to Europe and North America data

Let me swap Region with Airline and display some more capabilities

From Airline characteristic properties presentation can be changed as well as attribute display activated

As you  can see from screen shot above it is possible to:

  • Activate display of characteristic attribute (URL)
  • Change characteristic presentation (key and text)

Finally lets test characteristic variable

As you can from above screen shot Airline characteristic variable is working limiting data to LH and UA.

You can create demonstrated ABAP CDS Consumption View and all other underlying view using source code below.

    Hello Uladzislau,

    Thanks for sharing this example. Do you know how to asign a measure to the FREE axis?

    I know this is possible to do with dimensions using @AnalyticsDetails.query.axis: #FREE (as shown in your example), so that the data does not appear in the initial view but it can be shown just by clicking on Free Characteristics.

    I have tried using the same annotation with measures but it has not worked so far.

    1. Uladzislau Pralat Post author

      Hi Fernando,

      first of all, measures (key figures in BW terms) can not be in FREE axis (free characteristics).

      The same requirement in BW I would approach by filtering Key Figure structure to only key figures I want to see at, but I do not know how to do the same in ABAP CDS yet.

      Regards, Uladzislau

        If you want to hide a key figure then you can use

        @AnalyticsDetails.query.hidden

        With this the keyfigure is hidden at the beginning, but can be switched on by a user at runtime

         

        With @Consumption.hidden

        a key figure can be switched off at all and can’t be switched on by a user. This could be usefull, if the key figure should be used in formulas but the key figure itself is of no business reelvance

        Regards, Stefan

    A good one, Uladzislau! I especially like the use of annotation @AnalyticsDetails.query.formula:

    In GIThub your hierarchy file contains dimension code, though 😉

    Keep on going!

    Hi Uladzislau,

    Thank you for very informative blog. I’m wondering if you have find a way to have a dynamic column name in CDS view. I came to conclusion that this is not supported (yet). Maybe you know any work around i can use. For example, the query below has dynamic column name based on the period entered in the parameter.

    1. Uladzislau Pralat Post author

      Hi Iwan,

      it is possible in BW because this functionality was implemented prior to Business Objects acquisition. Dynamic headers is a requirement for front-end tool such Businesses Objects whereas ABAP CDS is a back-end. Separation of duties though.

    Hi

    Uladzislau Pralat .

    Very nice blog. I am one of the lead user of CDS view since we are on S/4 1605. I still see that there are few things missing in CDS  query (aka consumption view) functionality, like variables, value help/search help, cell level calculations etc. I want to get your view on one of the below issues that I am facing right now.

    I am trying to create use navigational attribute from a dimension view  (in your example, use currency code  from sapbc_carr_dimension  as a navigational attribute in the consumption view and can I have consumption filter in the consumption view on this navigational attribute . (I know in your case this maybe not make sense for currency code, but I am having a real life example of customer dimension having customer group as an attribute and in my fact table have customer and made the association to customer dimension in composite view . In my consumption view I want report by customer group but also have consumption filter by customer group.  (I am able to get consumption filter (value help) for customer since I made the association to customer in the composite view , but when I use the navigational attribute of this customer and want a consumption filter on such nav attribute , I am having trouble.

    Help appreciated.

    Interesting blog, I am not very familiar with BW but still learned interesting things about CDS views and annotations.

    I am curious about the reason that you hard coded the country names in ZSAPBC_SCARR. Is this normal in BW instead of getting it from a table like SPFLI, or is this just to demo something?

    (0) 
    1. Uladzislau Pralat Post author

      Hi James,

      from what I know country names are not available in Flight data model. Just extending existing data  model with additional information to demo some CDS features.

    could you help in guiding how to achieve below logic

    1. Go to KNC1 table, and provide the Company Code(KNC1-BUKRS), Customer(KNC1-KUNNR) and Fiscal(KNC1-GJAHR) and get the sum of all positive Balances carried forward(KNC1-UMSAV)
    2. Now repeat the same for last fiscal (Fiscal-1) and get the sum of Balances carried forward (KNC1-UMSAV)
    3. Average_Receivable = (c+d)/2
      1. From Table BSID, get sum of Amount in Local Currency (BSID-DMBTR) for the Company Code, Customers, Fiscal-1, Accounting document type(from selection screen if applicable), BSID-UMSKS=Blank, BSID-UMSKZ=Blank and BSID-SHKZD= ‘S’ (Debit).
      2. From Table BSID, get sum of Amount in Local Currency (BSID-DMBTR) for the Company Code, Customers, Fiscal-1, Accounting document type(from selection screen if applicable), BSID-UMSKS=Blank, BSID-UMSKZ=Blank and BSID-SHKZD= ‘H’ (Credit).
      • Subtract ii) from i) to get the net customer receivables
      1. Follow the similar steps with table BSAD to get the Sales_BSAD (Sales for which invoices are cleared)
      2. Annual Sales= Sales_BSID + Sales_BSAD

    Dear Pralat,

     

    Thanks a lot for the Blog; it is really helpfull.

    However, I am wondering if we can’t use the Bex Query designer on top of a #Cube CDS view, in order to make all these Bex artifacts, since I see that the development effort is multiplied when done with CDS, while in a Bex query it will be something quite stright forward.

    Do you know if there is any documentation about this around SAP?

    We are now starting our S4HANA migration and Embeded Analystics is a hot topic we need to define as soon as possible.

     

    Thanks a lot and best regards,

    Alfonso.

      Hi Alfonso,

      creating Queries using CDS views might look like a complicated and time consuming task, but it is only necessary for complex queries that users can not create. All simple queries users should create themselves in Query Designer App.

      If reporting requirements are too complex for CDS Query view (for example, you need to use customer exit variables) then you can always generate DataSource from CDS Cube view and bring data to BW (virtualize with the help of Open ODS or materialize loading data in delta mode with the help of streaming Process Chain).

      There is no one fit all solution. You should know all you options and choose one that is the best fit.

      Regards, Uladzislau

        Hi Uladzislau, Hi Alfonso,

        complex queries which can’t be defined in CDS can be defined in the Bex-Querydesigner/BW-Modelling tools directly on top of a CDS view of datacategory CUBE or DIMENSION. The name of the infoprovider is “2C” followed by the SQL-name specified in the CUBE-view.

        But you should keep in mind that the life-cyle of BW-queries is different from the life-cycle of CDS views (e.g. transport, SAP-content, where-used, …)

          Hi Stefan,

          I have not tried, but I am not sure that Queries created in BW Modeling tools will be visible in S/4 HANA Query Browser.

    Hi  Uladzislau Pralat ,

    How does Aggregation takes place in ABAP CDS views?

    I am trying to understand the following annotation @DefaultAggregation: #SUM. Just by specifying this annotation does aggregation of measure takes place against any dimension/attribute.

    Or, it is like we have to use SUM() aggregation function and group by clause in order to aggregate data for a measure against any dimension/attribute.

    Need your inputs here, please.

     

    Regards,

    Mohammed Sami

      Hi Mohammed,

      @DefaultAggregation annotation defines default aggregation behavior for measures. Measures are aggregate by dimensions in drill down.

      In my query I put Region in drill down (annotated by @AnalyticsDetails.query.axis: #ROWS) it means that all measures are grouped by Region. There are other dimension that are not in drill down (annotated by @AnalyticsDetails.query.axis: #FREE) but can be put in drill down. Users might change drill down then group by will change.

    Hello Uladzislau

     

    Thank you for sharing this great article.

    I do have a question though around BEX selection. Would it be possible to create a ‘characteristic’ selection through CDS view?

    For example, I have a “GL_ACCOUNT” characteristic which has many values (Sales Income, External Sales, Labour, Overheads, Rent etc).

     

    I’d like to create two selections (structure) in ROWS based on the GL_ACCOUNT that shows “Sales Income” and “Rent” only and I’d like to use the two selections above into a formula (I understand how to create the formula), but I just having problem with creating a structure characteristic selection through CDS view. If you could shed some light, that would be very appreciated

    Thanks in advance

     

    Kind regards

      Hi Galvin,

      there no equivalent for BEX structure in CDS Views, but you still can fulfill your reporting requirements by creating 3 restricted measures as described in my blog (first for Sales Income, second Rent and third for Sales Income and Rent).

      Regards, Uladzislau

        Hi Uladzislau

        Thanks for your reply.

        On a separate note, We are using the standard pre-delivered “embedded analytics” CDS views for one of our project. We obviously need to do few enhancements to it (adding filters, fields, etc).

        What do you think is the best practice in terms of modifying standard CDS views (do you create your own views which extends the standard delivered views? or modify directly the standard pre-delivered views?)

        There are concerns that any potential upgrade might impact the standard SAP pre-delivered views (at the same time we tried to always utilize standard delivered CDS as much as possible). I thought I’d get your input around this if you may

        Thanks again

         

        Kind Regards

        Galvin

    Hi Uladzislau

    It’s me again

    I’d like to ask you about please with regard to your consumption view,

    In the below statement , how is it possible to set the “default value” of the parameter dynamically? (like a customer exit in BEX)

     

    For example, I need to set the default value of my “year’ parameter into “current fiscal year” or “current fiscal period”?

     

    @Consumption.defaultValue: ‘2016’

    p_year_1: rscalyear,

    Thanks in advance again

     

    Kind regards

    Galvin
