Looking for wisdom on HRMGE0090 the employee merge program

Hey folks,

I am looking for some help with the employee merge program HRMGE0090.

I have looked through the documentation and cant find much detail on how it configured or tailored and i cant read ABAP - or any other historical language.

Does anyone know what variables are configurable or customisable, for example can we add more infotypes into the merge process (for example our customer specific infotypes).

Can we change how the merge works on an infotype by infotype basis - for example take the IT710 from the home record, not the host records?

Any wisdom greatly appreciated and rewarded with beer!

Thanks a lot,

Greg
