interface for function module is incorrect in ALE inbound processing
I have created a custom function module and i assign this FM
to the custom process code for ALE INBOUND process and i already assigned this Fm to message type and basictype in Tcode we57.i have assigned this process code to the msgtype in WE20 also.
But while trying to execute the inbound function module through WE19, I get an error message: "interface for the function module is incorrect". What could be wrong?
