Issue with IT0031 and Central Person and Business Partner (HRALX PBPHR)

Hello

the following issue appeared in our system:

I have two employee numbers (P1 und P2) that I need to link via IT0031 to make sure they have the same Central Person ID (CP). P1 already has a BP-relation (BP1) - the other doesn't.

When I am now trying to save IT0031 I get the message that P1 and P2 can not be linked - but what is worse, P2 (the one formerly without a BP-relation) now has a BP2 even though nothing was saved in the infotype.

It seems to have something to do with HRALX PBPHR because if I switch the parameter off in T77S0 I am able to link the two P (and therefore make sure only one CP and one BP relation exist) - but is the parameter activated it will generate a new second BP even though there is no cause to do so.

Does anyone know how to fix this?

Unfortunately, I can't let the parameter HRALX PBPHR switched off, so I need some sort of work-around. Any help is appreciated. 😊
