Accounting Documentation counter(999) limitation.

Hi,

If a PO or SO has got some 300 or 400 line items and also if it has got some delivery conditions(in case of PO),then when I do MIGO(wrt to PO), system gives counte limitation error of 999(since the entries exceding 999).In that case I have to split the GR so that it stays below 999 entries in accounting document.

I believe this is standard practice.But also there is some provision like summerisation.I want to know how that can be used here to av oid splitting and what and where the settings are required to be done.

Regards,
