How does SAP lookup the Partner in Gentran?
Here is how Gentran partner look-up is resolved:
Partner Reference SAP screen
- It uses the Fields that you say *YES to in the Partner Reference SAP screen and appends those *YES fields from the EDI_DC record to look up that partner.
So, if the parm RCVPRN selected as *YES, then that value in the EDI_DC record would be 1) the Partner ID (it looks there first), then 2) cross reference screen.
Finally make sure the Application Partner Reference Field = ###SAPTP Partner field
When it finds the partner the resolved partner gets placed into the ###SAPTP record so it can sort it properly.
