Diagnosis
The delivery that you selected has not yet been posted togoods issue.
Please keep in mind that, in the delivery schedule, the systemautomatically sets the cumulative received quantity to the cumulativedelivered quantity of the last delivery you selected if thecumulative received quantity field is not filled. This occursregardless of whether the delivery is actually posted to goods issue.
This results in the open quantities being redetermined due to thedelivered quantity of the selected delivery.

Procedure
Assign deliveries that have not yet been posted to goods issue only ifgoods issue has taken place physically and if the customer has receivedthe goods. Otherwise, the system will not be able to give a correctrepresentation of the delivery situation.
The system does not take into account correction deliveries whenchecking for GI posting.
