Part II：Copy WM Quantity = 2 (Copy WM quantity as delivery quantity and post GR/GI)
1, we maintain the value of the field "Copy WM quantity" into 2 for the warehouse number NM1 movement type 601.
2, we created below sales order and delivery document for the material 800.
Delivery QTY = 100 EA.
3, Execute the transaction code LT03 to do picking for this outbound delivery.
Suppose we just picked 88 EA for this delivery. Click Save, then TO#101 was created, and then we confirmed this TO.
Execute the transaction code VL03N to display the document flow of this outbound delivery.
We can see that the goods issue has been posted.
To see the delivery quantity of delivery note,
The delivery quantity of this outbound delivery was changed into 88 EA, of course the picked quantity was 88 EA too.
This is the effect when Copy WM quantity = 2.
However, in the projects I participated in, almost no project set the value of copy WM quantity field as 2. This function is very good and automatic, but it is not applicable in business practice. After picking, the warehouse operators may often need to re-pick for various reasons. If the picking has been completed, the goods issue will be posted automatically. When handling picking errors, they also need to cancel the PGI in advance, which brings trouble to the business personnel.
Part III: Copy WM Quantity = 4 (Do not take WM qty as delivery qty, but post GR/GI)
1, we maintain the value of the field "Copy WM quantity" into 4 for the warehouse number NM1 movement type 601.
2, we created below sales order and delivery document for the material 800.
Delivery QTY = 50 EA.
3, Execute the transaction code LT03 to do picking for this outbound delivery.
We just picked 45 EA for this delivery. Save it, the TO#102 was created, we confirmed this TO document by transaction code LT12.
Check the document flow for this outbound delivery,
No PGI was done. Execute VL03N to display this delivery,
When the picked qty is smaller than the delivery qty, after TO confirmation, the delivery quantity will Not be updated, no PGI.
Continue to do picking,
The picked qty is 5 EA, save it and created the TO#103，confirm this TO.
Now to check the document flow of this delivery,
The PGI was done automatically. It means that when the value of Copy WM quantity =4, SAP will automatically done PGI only when the picked quantity equals to the delivery quantity.
This is the control function when Copy WM quantity =4.
However, in the projects I participated in, almost no project set the value of copy WM quantity field as 4. This function is very good and automatic, but it is not applicable in business practice.
