Change existing data extracted by the standard extractor
Is it possible to use the user exit ZXRSAU01 to change the data content extracted by the standard extractor.
I am working with one of the LO extractors, and I would want to change the field ERNAM to get it from some other table instead of the table that the standard extractor gets it from.
I tried the code from ZXRSAU01 and it doesn't seem to change the existing data.
Is the user exit only used for filling and not changing the existing data extracted by the LO extarctors?
