RFC Lookup in graphic mapping

[former_member260907]

Hi Expert,

I have a Flat file to IDOC scenario. I have one field have to get it from R3 side's table with input from flat file, then map it to the field in IDOC. To make more clear, it will be like this:

input: field1, field2 --- from flat file

output: field3 - from R3 table table1 based on the input field1, field2

filed3 maps to field4 in IDOC.

In PI graphic mapping, I see there is a RFC Lookup conversion function. Could anyone provide a sample on how to use this function to meet my need?

Thanks a lot!

Charles

Hi Santhosh,

Thanks for the information. I followed your link on RFC lookup. But seems I missed one step. How I can pass the real communication channel name as the value to the parameter (RFC_channel) defined under Signature? When I test my message mapping using "Test" tab, I can manually give the value under Parameters tab.

Thanks,

Charles

Hi Charles,

For regular runtime processing, you define the Communication Channel to be used by the Lookup inside your Interface Determination object. First, you define the paramter in the Message Mapping, as described here: http://scn.sap.com/people/jin.shin/blog/2008/02/15/sap-pi-71-mapping-enhancements-series-graphical-s.... I believe you have already done this, based on your post above.

Later you provide the parameter with a value in the Interface Determination, as described in section "Setting Parameter Values in Interface Determination" of this blog: http://scn.sap.com/people/jin.shin/blog/2008/02/14/sap-pi-71-mapping-enhancements-series-parameteriz....

Hope this helps,
