Question:
Hello. The developer of the middleware that calls my function module through RFC experienced this error:
When calling the function module XXX, ONE OF THE PARAMETERS NEEDED ACCORDING TO THE INTERFACE DESCRIPTION WAS NOT SPECIFIED
THIS PARAMETER WAS YYYY.
What does this mean? What needs to be done to correct the situation?
Answer:
Did it actually say XXX and YYYY or did it give you names?
It sounds like one of the mandatory fields for the Function module was not passed during the RFC call.
Answer:
This was answered in the General forum yesterday.
