Hi SAPHR 88,
Scott is correct - I would start by going to SM30 and looking at T588M. You need to look at Module Pool MP018500 for Infotype 0185. You can also check Feature P0185 from transaction PE03 to see the variable key for different countries for this table. Could be some customization there that is messed up.
Here is an example of what it looks like in a sandbox system.
Thanks,
Imran
