VA01 Item Overview Sorting

[#1]

Is it possible to change how the order of items are being displayed/sorted in VA01 Item Overview? 

This is how the items are being sorted once I create them. The grandchild is being sorted on top due to a requirement for how the POSNR is being incremented:

• 4. Grandchild
• 1. Grandparent
• 2. Parent
• 3.  Child

I need to sort it like this:

• 1. Grandparent
• 2. Parent
• 3.  Child
• 4. Grandchild

Is there a way to sort it using a different field in VBAP instead of POSNR?

In standard VA01, the item overview is always sorted by POSNR. You cannot change the sorting to another VBAP field through configuration.

How about through user exits?
