In Sales Order Change report (VA02), there is an sales item for the material with BOM tree,
There are production orders tree correspondingly generated for this material,
After the production orders are released, when we try to change the characteristic this sales item, some unexpected change will automatically happen:
1. top production order will be set with status: created (CRLT)
2. lower production order will be replaced with newly created lower production order (with status CRLT)
I'm a little confused, why this happen?
How can I prevent it from happening?
Thanks in advance
