Cost Center & Cost Element Group

Hi All,

I have a customized report in which I have Cost Center & Cost Element Group in the selection screen. Cost Center Group is linked to CSKS-KOSAR and Cost Element Group is linked to CSKB-KATYP. Therefore i get only few entries when i press F4 on these fields.

Now the requirement is that these F4 helps should display all the entries as we have in transactions KSH1 and KAH1.

Can anyone tell form which field KSH1 and KAH1 are picking up the values? Also how do we add this in my report?

Thanks & Regards,

Naba
