Troubleshooting SAP BAPI / RFC Calls

Problem

If you have configured an SAP BAPI / RFC Message Format / Map in NLINK and it isn't working as expected, here are several steps you can take to verify that your configuration is correct.

Solution

Documentation

Be sure to read any documentation available in the SAP system.

1. For BAPIs, look in transaction BAPI to see if it is listed there.
   Watch: Access SAP BAPI/RFC Documentation in transaction BAPI
2. If you cannot find it there, you may be able to get to some documentation through transaction SE37. This is generally less helpful (and often not available in English) but it's worth a try.

Test in SE37

Especially for very complicated calls, it's a good idea to verify that the BAPI/RFC does what you think it does by testing it in SE37. Generally speaking, if you can get it to work in SE37, you can get it to work from NLINK.
