How to hide subtypes from standard infotype 21 in ECC6.0 ?

Hi All,

I encounter the following problem : we've upgraded our customer's SAP HR system from 4.6c to ECC6.0 and new standard subtypes for infotype 21 appear (especially when you press F4 or use the entry help button in transaction PA30) ...

And our customer askes us to remove these new one ... so I made my research and finded in the IMG : 'BAdI: Set Up Entry Help for Subtypes' ... Then I clicked on it, a window appear and I choose the corresponding line for IT0021 ... but I don't know what to do after that ? I tried to create a new implementation with name terminated by 0021 (like proposed in SAP standard help) but I encountered a blocking message about the Filter type (defaulted at INFTYPA and not modifiable).

Before that, I found the view V_T591A but it doesn't seems to be indicated to remove line from this table to solve my problem, that's why I continued to investigating and finally find the 'BAdI: Set Up Entry Help for Subtypes'.

Then I desactivated the Badi and the system asked me a transport request ... now I try to re-enable it and the system ask me a repair key At this time, I didn't make any change in the system.

I really don't know what to do ... Could you help me ?

Only one thing makes me happy : I did this in the sandbox system and our other landscape's system are not impacted by my research ... Ouf !

Have a nice day / afternoon / night !

Sincerely yours,

Alexandre.
