Error when device replacement (Rate data is no longer consistent)

Hi everyone,

I'm trying to device replacement with FMs ISU_S_WORKLIST_INSTALL_PROVIDE and ISU_S_WORKLIST_INSTALL. I'm thinking to call this FM with the right inputs. The device which is removal have 3 registers and the device which is installation have 5 registers. The system can not allocate a logical register number for new device. Then it give me a error  'Rate data is no longer consistent' ( EN 470 ).

Note ' 1970759 ' says you can implement your custom logic to determine a valid LOGIKZW in exit EXIT_SAPLEG60_001. But i couldn't find how can i determine a valid LOGIKZW in this user-exit.

Can anyone help me ?

Regards,

Okan
