The are situations where customers need to control the sales orders/deliveries/invoices depending on the credit level ceiling that was assigned to their customer.

The calculation for the authorized credit level is based on Orders, deliveries not invoiced, and invoices not posted etc.

In certain scenarios unposted invoices, payments, account balance are not included in the calculation of the authorized credit level.

Solution:

Check the OST parameters in VEN and TC, the OSTORD sets whether open orders are included in the total.

Activate the field "Credit level update" (GACUPDBLC) to in Common data > G/L accounting tables > Accounts> AR Control account to Customer instead of No then run customer balances resync.
