Field AKTYP in FM MARA_MEINS

Hi,

Can anyone please let me know how importing parameter AKTYP is used in FM MARA_MEINS.

I went through whole FM including sub-routines but i didnt find usage of this field anywhere in FM.

I am planning to misuse this field in 1 of the enhancement option but just want to make sure it doesnt blow up anything else.

Any pointer will be appreciated.

Thanks

Puneet
