I have entered the cost center 'X' in the item of the sales order and the GL account / any cost center combination is not exist in OKB9.
i did not get any error while doing PGI saying like " the account is not assigned to an CO object"
and my accounting doc, the GL account is posting to cost center 'X' whatever i gave in item of the sales order.
But for the other sales order there also i have gave cost center in item, but got the error while doing PGI saying "the account is not assigned to an CO object ". so i assgined CC 'Y' for that GL account in OKB9.
when i see the accountin doc, the Gl account is posting to CC 'Y'
Could please explain the internal intergration / link related this issue.
