We have done a test set up of CIG Mapping PurchaseOrderExportRequest/AddOn/0000".
We create a PR from Buying for vendor A and now the PO is created in ERP.
If we do the same for any other vendor, No PO is created.
There are NO error messages in SRT_MONI or Dumps in ST22.
In SLG1 , it provides information 'Start of RFC authorisation check' and 'start Execution of Business logic'.
The only difference we have found for the vendor that works is that this has 'Electronic Purchasing' as its preferred purchasing method in the master data. All others are Email. This setting worked without issue in CI9.
What is missing in our set up?
Thanks for help.
