Automation of the Data Load from SAP R/3 to BI

This is my First Blog, hope this will be useful in your future projects.

This blog is meant about pulling data from R/3 System to BI System automatically from R/3 system without logging into the BI System with all the User Selections.

The Sap ECC User can easily load this data and getthe status of the data load without logging into BI System.

Scenario::

Caution: This is just an example not real scenario.

There is a company where the User wants to forecast the sales by viewing Actual sales. Then he post the data from ECC and load the data to BI where he can also send data to Application server through the open hub destination and then can check his data in SAP BPC (Business Planning and Consolidation) and after viewing this report if he wants to change the Forecast values he can do and load again as he wish.

I’ll clearly explain this with an beautiful example provided with the ABAP program code.

Coming into the work, First, we have to create a Process chain on the BI side.

For example: Here i want to load data for a Cube from COPA datasource. So, i’ve created a Process chain from the Datasource toDSO and DSO to Cube. From here the Data is sent to BPC (to Application server) where the data is used for BPC through the Open Hub Destination.

Hope this process chain creation is not a tough job for you guys, anyways for simple cut-off discussion to small, we can create the process chain the RSPC (T-code).

After the creation of the Process chain, you can create a T-code with ABAP Program where the program code is given below for your reference.

You can make your own changes as per your requirement.

ABAP PROGRAM::

Here our program is the ZTEST_BI, this program has to create on R/3 side.

I’ll clearly explain how this program works.

1. We need to make a selection screen for the Process chain, User parameters(here i took, Controlling area, Costcenter, Cost element, Fiscal Year/Period, Version. You can give your own parameters)

2. In order to get the Process chain list we need to use this Function Module: ‘RFC_GET_TABLE_ENTRIES’ from the table ‘RSPCCHAIN’ from BI System,here we need to provide the BI system client.

3. In order to embed these Process chain list with ‘F4′ functionality we need to create a FORM with the function module ”F4IF_INT_TABLE_VALUE_REQUEST’.

4. The User values (Parameters) from the selection screen can be uploaded through a remote function module to BI system.The function module here is ‘ZIP_SEL_FM’. This function module send the user selection values to BI generic table. The function module code is given below.

5. To create a generic table we need to use SM30(t-code).

The above are the functions done by Program.

Here the Program name is “ZTEST_BI

REPORT ZTEST_BI.

We should Create a Remote Function module in order to save the user parameters in the BI System from R/3.

MODIFY zip_sel_tab3 FROM TABLE gt_itab.

 

ENDFUNCTION.

Here ZIP_SEL_TAB3 is the Generic Table which is created from SM30(T-code). The user selections from R/3 are updated to this table.

This table is also used for the DTP restrictions within the ProcessChains.

The example code for the DTP restrictions::

TABLES: ZIP_SEL_TAB3. (This is in the Global declarations)

The code mentioned below is for picking up the User selections from the Generic table to the DTP selections.

data: l_idx like sy-tabix.

  read table l_t_range with key
fieldname = ‘COSTCENTER’.
l_idx = sy-tabix.
data: l_DTP type RSBKDTPNM.
data: l_CHAIN type RSPC_CHAIN.
data: l_seltab type ZIP_SEL_TAB3.

 

l_DTP = I_R_REQUEST->GET_DTP( ).
SELECT single ACTUALCHAIN from RSBKDTPSTAT into l_chain
where DTP = l_DTP.

 

Select * from ZIP_SEL_TAB3 into l_seltab
where RSPC_CHAIN = l_chain
and   FNAM     = ‘KOSTL’.

 

l_t_range-fieldname = ‘COSTCENTER’.
l_t_range-SIGN = l_seltab-sign.
l_t_range-OPTION = l_seltab-opt.
l_t_range-LOW = l_seltab-LOW.
l_t_range-HIGH = l_seltab-HIGH.
if l_idx <> 0.
modify l_t_range index l_idx.
else.
append l_t_range.
endif.
ENDSELECT.
p_subrc = 0.

Based on the above steps and ABAP code the peculiar requirement from clients can be achieved.
