HRMGE0090 changes P0001-ENAME ?

Hi,

I used function module HRMGE_MERGE_CP_RELATIONSHIP from program RPMGE_CP_RELATION_MANIPULATION (behind the transaction HRMGE0090)

in an own report and it worked fine.

Now we are facing a problem:

If  we run the program for british employees with logon language DE the P0001-ENAME is changed from "Mr" to "Herr" ...

Why?

How to prevent this?

Thanks in advance
