Postings For FB50 using BAPI's

Hi All,

I have one doubt, i am doing batch upload for transaction fb50.

1)My requirement is that from the flat file i have to check if corresponding

to one refrence number if the line items in the flat file are more then 999

then the internal table should break and those 999 line items should get posted.

And the line items which are after those 999th line item should also get

posted for that same reference number.

2)And how will i assure that those 999 line items which are getting posted

after breakage have the debit and credit amount equal so as them to get

posted using bapi's and same for the line items after that 999th line item.

The bapi's i am using are:

BAPI_ACC_GL_POSTING_CHECK

BAPI_ACC_GL_POSTING_POST

BAPI_TRANSACTION_COMMIT

Kindly help.

Regards

Mansi
