What causes this issue?

In the case of process codes for inbound processing, which are created
for processing via function modules, the ID - the processing function
module here - is not maintained from this screen, but in the ALE table
'Function modules for ALE-EDI inbound processing'. In addition, further
entries are required for this combination.
In order to be able to use process code &v1& for processing, an entry
for this process code must also exist in the ALE table.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Include an entry for process code &v1& in the ALE table.
