F.19 Posting logic

Hi Experts,

I read in the thread Item grouping of F.19/ GRIR clearing that the adjustment postings are created per company code, GR/IR clearing account, reconciliation account, and business area. Is this the standard? Is there a way to change this logic through a config? F.19 posting logic in my system seems different and I am unable to figure it out.

Any help is much appreciated.

Thanks,

Em Jay
