Prerequisites
You enter a goods issue for an order by referencing the relevant order or reservation. To reference the order, proceed as follows:
Procedure
This takes you to the initial screen for this function.
You need not enter the movement type or the plant, as these are automatically copied from the order.
A dialog box for selecting the reservation appears.
If you know the order number, enter it directly. Using the By-products indicator, you can simultaneously post the goods receipt of planned by-products (refer to Goods Receipt of By-Products). Using the Choose transaction/event (Ch.trans/event) indicator, you can display all transactions/events for an order and choose the transaction/events for which you want to post a goods issue.
If you do not know the order number, you can search for the corresponding reservation using various selection criteria (refer to Searching for a Reservation Number).
