Using Datafeed we can upload Market data into SAP automatically from different Market data providers.
I want to show you an example how you can use Datafeed.
Input data
I have a web site of National Bank of the Republic of Belarus ( Exchange Rates, Refinancing Rate, News | National Bank of the Republic of Belarus) from where i can get information about:
- Refinancing Rate | National Bank of the Republic of Belarus
- Official Exchange Rate of the Belarusian Ruble Against Foreign Currencies Set on a Daily Basis | N...
- Accounting Prices on Precious Metals in Standard Bars, Set By the National Bank of the Republic of ...
Each of mentioned Market data has API which can retrieve information. API is the URL with parameters. API returns a string with information.
- For Refinaning Rate - http://www.nbrb.by/API/RefinancingRate?onDate=2016-7-8.
Parameter "onDate" is the date on which we want to get information.
- For Exchange rates - http://www.nbrb.by/API/ExRates/Rates/Dynamics/190?startDate=2016-6-1&endDate=2016-6-30.
Parameters: "startDate", "endDate" are the date on which we want to get information and "XXX" - external codes for currencies.
- For precious metals - http://www.nbrb.by/API/BankIngots/Prices/0?startDate=2016-6-1&endDate=2016-7-30
Parameters "startDate" and "endDate" makes period for each we want to get information.
As a result we need to get information into SAP and parse it into the special table "Answer".
Before we can use Datafeed, we need to configure the system.
Configuration
Create Market Data Provider
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Technical Settings -> Define Datafeed Name (tr. S_ALR_87007834)
Here we create Market Data provider in order to separate the different sources of information:
- Data provider - name of data provider.
- Usage log - If you need to log all data retrievals. SAP Menu -> Accounting -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Usage Log -> ...
- Feed active? - distinguish active and inactive feeds.
- Quotation source - Quotation source for commodity.
RFC Settings for External Partner Program
We can contact external partners in two different ways:
- Using RFC (remote function call) and calling external funciton.
- Web Access (URL or Web Services).
Let's start with Web Access.
In my case i will use Web Acces.
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Technical Settings -> RFC Settings for External Partner Program -> Assign Datafeed RFC Destination (tr. SM30 -> V_VTB_DFD)
- Datafeed operating mode:
- •'1' synchronous: SAP waits until the external partner program has delivered all the data.
- •'2' asynchronous: SAP does not wait until the external partner program has delivered all the data but immediately switches control back to the calling program. The data is delivered from the external partner program at a later date (possibly in separate blocks).
For Web Access we choose Synchronous operation mode.
- Function: There is a standard SAP function module TB_DATAFEED_INTERNET_ACCESS to get information from web. But as i described earlier my data provider has special API - so i need to modify standard FM. So i created ZTB_DATAFEED_INTERNET_ACCESS
- RFC destination, Back-up RFC destination: For Web Access in my case i do not need RFC connection.

Using RFC
For RFC we need to Enter our RFC destionation (tr. SM59, RFC with type T (TCP/IP) ) and indicate partner's function. For example, with RFC we connect to Data Provider and the SAP calls special partners function in order to get Market data. Usually, you can get description of RFC configuration and list of function from your partner (Reuters, Blumberg, Teletrade, etc). Using RFC we can retrieve information in Real-time if your provider allows it.
Internet settings for WEB Server Access
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Technical Settings -> Internet Settings for External Partner Program -> Define Internet Settings for WEB Server Access (tr. SM30 -> V_VTB_DFD2)
Here we define URL (required) and User name and Password (optional) if your Data Provider requeres it.
As you can see earlier in URL we have constant part (http://www.nbrb.by/API/) and variable part depending on market data class.
So in this configuration i will put constant part. Variable part is added inside of FM ZTB_DATAFEED_INTERNET_ACCESS.
Proxy Configuration
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Technical Settings -> Internet Settings for External Partner Program -> HTTP Proxy Configuration -> Define Proxy Configuration (SM30 -> THTTP)
If according to your companie's policy you use Proxy to enter to internet, then you can configure your proxy with Proxy user and Proxy password.
Define Data Sources for Datafeed
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Translation Table -> Define Data Sources for Datafeed (tr. S_ALR_87007888)
Here we define different Data Sources of our Data Provider.
Translation Table
Translation tables can be filled in two ways:
- Automatically. You need to configure Datafeed Conversion Codes
- Manually.
Translation Table: automatically
Create Tables for Code Conversion
This operation fills Converstion tables with SAP data: Exchange rate types, Currency names, etc.
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Translation Table -> Define Datafeed Conversion Codes -> Create Tables for Code Conversion (tr. TBDK)
Convert Codes for Exchange Rate Types
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Translation Table -> Define Datafeed Conversion Codes -> Convert Codes for Exchange Rate Types (tr. SM30 -> V_MDUDFCV)
Before creating tables for Code Conversion, the table was empty. After creating tables - it will be filled with SAP data. All you need to map SAP Data with External Providers' data.
In our case SAP data is equal to External data.
Adjust converstion tables to your need: IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Translation Table -> Define Datafeed Conversion Codes -> ...
For my purpse i created the following talbes:
Convert Codes for Currency Names: tr. SM30 -> V_MDUDFCR
Convert Commodity Price Types: tr. SM30 -> V_MDUCMV
I will use these tables to get external codes for currencies and commodities.
Import R/3 Master Data
Now it's turn to create Translation tables Automatically.
- First select Master data: for example Currency.
- Then select Quantity. If you leave these fields empty then all combination of currency 1, currency 2 and rate type will be uploaded into translation tables. I will use combination of BYN-USD, BYN-EUR, BYN-RUB with rate type M. So, field "1 key definition" is filled with BYN, field "2 key definition" if filled with USD, EUR, RUB. Rate type is M. For mentioned field there is a help, data inside these fields depends on Master data: currency, security, etc.
- Datafeed: "Name" is NBRB.by, "Data source" is Currency.
- Test run - to test if transaction works perfect.
- Save market data - if you want to save data into Translation tables.
Start transaction.
Now we see, that SAP selected what we requested on selection screen. If you uncheck Test field, SAP will fill translation table for Currency. Let's see this translation talbe.
Translation Table: Currency
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Translation Table -> Define Currencies (tr. S_ALR_87007920)
Select you data provider.
SAP created translation tables for currency. Make a double click on any parameters in the table.
Most of fields are entered by SAP, selected fields with red box - you have to enter yourself.
- Save markter data permanently in system: tell your system to save data into SAP tables. For example, Exhange rates - tr. OB08, Reference Interest rates - tr. JBIRM, etc.
- Instrument - ask you data provider about this data or create your own. I created my own Instrument - combination of currencies.
- External data feed currency settings: according to external data.
If you didn't use Automatic creation of Translation tables then you have to fill these tables manually.
Translation Table: Interse rates
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Translation Table -> Define Reference Interest Rates (tr. S_ALR_87007812)
Translation table for Refinance rate.
Translation Table: Commodity
IMG -> Financial Supply Chain Management -> Treasury and Risk Management -> Basic Functions -> Market Data Management -> Datafeed -> Translation Table -> Define Commodities (tr. S_ALR_87007868)
Translation table for Commodity.
That's all. For configuration.
Conclusion
If your provider is Reuters (or Bloombers, or Teletrade, or similar services) - it's very good. Reuters, for example, is licensed with SAP to provide market data. All you need is to configure RFC connection, list of Reuters functions to call and translation tables.
If your data provider has Web-Services or APIs - it's also not a problem to get data. You have to retrieve simple data structures and parse them into the SAP tables.
Even if you have access to data which is presented as a web page - you can get this information also (as HTML), but you have to find out how to parse this information.
Now it's time to process datafeed market data: TRM Market Data Management: Datafeed: Processing market data.
