I want to use a function module to read certain data from the
material master record. But the Call statement doesn't return
any values. In the SAP test environment SE37 the function
works correctly. What could be the reason?
many cases the reason is that the internal format of the material number is not
identical to the external format. The external format might contain leading
zeros or special editing characters. Please either use a function module that
converts the material number from external to internal format:
exporting INPUT = material
importing OUTPUT = material.
Or, if you are sure that no special editing characters are used, only leading
zeros, you can simply add them via the ABAP statements
