I am working in a program where I have to create a function module which selects data from another system, and compares it to the actual one.
In this case, a list of customers is in the two tables, but these customers may have different KUNNR's in the two different tables. So, I have to compare the KUNNR in the actual system with the KUNNR in the other system. Then, I have to show a list with the customers which have different KUNNR's in the two systems. Can somebody give me an idea of how can this be done?
Thanks in advance
