Query on RFC Function Module

[former_member234749]

Hi All,

I have a query on Idoc to Idoc scenario  based on the input field values from sender idoc i need to access SAP R/3 table and send the corresponding value to target side (IDOC).

Can you please suggest what is the best way of accessing the SAP tables either by creating the RFC Function Module which can be used in the UDF to access the table or any chance of  writing UDF to access directly the SAP R/3 table.

Please help me on this.

Thanks in advance

Create function module and do the lookup in the mapping to access the table. what PI version do you use? If your PI version is 7.1 and above, you can use RFC lookup readily available as graphical lookup function.  If your version is below 7.1., then you need to use UDF in the mapping.

Hi Baskar,

I am using 7.0

Not possible to access SAP Tbale directly,hence you need Function module,take help from ABAP team to create Function module .

SEARCH IN SCN RFC LOOK UP IN PI 7.0 , you need write JAVA code to perform RFCLookup in PI 7.0

Then you can write udf for the RFC lookup. You might want to see this code snippet for doing this.,,
