open item conversion- Accounts receivable.

Accounts Receivable Open item conversion

We have around 2 million open items to be converted.

there are many OA, AO and AU items to be converted. when we load them in pending_item table its giving an error accounting entry out of balance. my question is these entry types are assigned to automatic entry types and associated system function WS-05, WS-06, WS-07 etc.

Is there a way to load OA, AO and AU to pending item table and post it to item table after running ARUPDATE?

Thanks

Lakshmi
