Fixing error during SAP iDoc PORDCR1 integration

An SAP user is receiving an error message while integrating SAP iDoc PORDCR1 for a purchase order.

I am trying to integrate SAP IDoc PORDCR1 to create a purchase order, but I am getting the following error message:

"Function module not allowed: APPL_IDOC_INPUTI"

The error appears even if I change the process code for my partner. Is there a way to fix this?

The error message is caused by the function not being registered by the developer in table TBD51; you can edit the table with SM31 and insert the function. Whether this is sufficient I cannot tell right now; maybe more customizing is needed to also find the right SAP BAPI.

When you say that you changed the process code, the new process code is most likely not the one that you really wanted. I cannot give more advice without detailed information about your intention and the context you are using it.
