Upload Data from R/3 System using a Function Module in GenericExtraction to a DataStore Object in BI

By Pritam Ghosh, YASH Technologies

STEP 1: Create an Extract Structure in SE11 according to your requirement; here we will create a

structure for Shipment Item details for a

Delivery:

Here select the radio button for Structure & click on Enter.

Give a Short Description for the Structure & add the necessary fields as shown below, then Save &Activated your Structure (try to maintain the Enhancement category for the structure).

STEP 2: Go to t code SE80 & copy the function group RSAX & give the name as ZZRSAX for the newfunction group & then copy only the function module RSAX_BIW_GET_DATA_SIMPLE asZZRSAX_BIW_GET_DATA_SIMPLE as shown below:

Now go to the Tables tab for the FM ZZRSAX_BIW_GET_DATA_SIMPLE & change the Associated Typefor the parameter E_T_DATA as ZZVTTPLIKP (Extract Structure that we have created using SE11 in step1) as shown below:

Now go to the source code of the FM & do the below change & then Save & Activate the FM Group andthe FM.FUNCTION ZZRSAX_BIW_GET_DATA_SIMPLE.*"----------------------------------------------------------------------

STEP 3: Go to t code RSO2 & create a DataSource with the same name that we have used in our FMi.e., ZZ_SHIPMENT_DATA & as we are uploading transactional data so select the radiobutton forTransaction data as shown below:


6/16

Select Application Component as SD & maintain the text for short, medium & long description & then click

on the tab Extraction by FM as shown below:

Now enter the name of the Extract Structure & FM that we have created in step 1 & 2 respectively & thenclick on Save:

Give the selection condition & click on save:


7/16

STEP 4: Go to t code RSA3, enter the name of our DataSource & click on Start Extractor to check thedata in the datasource using Extractor:

STEP 5: Go to t code RSA1 in our BI system, here go to DataSources, right click on applicationcomponent Sales and Distribution & Replicate data as shown below:


8/16

Click on Continue & proceed as shown below:

Double click on the DataSource & Activate it as shown;


9/16

STEP 6: In RSA1 click on InfoProvider in the right hand panel, create an InfoArea & then create aDataStore Object in it as shown below:

Select the content for the DSO & Activate it:


10/16

STEP 7: In RSA1 click on DataSources in the right hand panel, go to our DataSourceZZ_SHIPMENT_DATA & right click on it & click on Create Transformation as shown below:

In the Target of Transformation give Object Type as DataStore Object and name of DSO that we havecreated in Step 6 as shown:


11/16

Create the Transformation & Activate it:

STEP 8: Go to DataSource ZZ_SHIPMENT_DATA right click on it & create InfoPackage as shownbelow:


12/16

Give a description for the InfoPackage & click on Save:

Now go to tab Schedule & click on Start as shown below:

Now go to the Monitor

STEP 9: Right click on the DataStore Object ZDEMODSO & Create Data Transfer Process as shownbelow:

Click on Continue, Activate it & then click on Execute:

Click on Yes as shown below to continue:


14/16

STEP 10: Right click on the DataStore Object ZDEMODSO & click on Manage to check the result:

Go to the Content tab of InfoProvider Administrator screen & click on New Data as shown below:

Now click on Execute:
