Document-Neutral Reversal 
Use
You can use this function to reverse already backflushed quantities and activities.
Whereas document-specific reversal only allows you to reverse the complete quantity and activities contained in a backflush document, you can use the document-neutral reversal to partly reverse a backflush.
Document-neutral reversal is particularly useful if you separate the backflushing processes. When the backflushing processes are separated, all references to the original document are lost. Therefore, you have to reverse without referencing the document.
Note
If the routing has been changed since backflushing, the system cannot take this into account in a document-neutral reversal. It therefore uses the current routing for the reversal.
The document-neutral reversal also allows you to post negative delta activities which means you can correct previously posted planned activities.
Caution
Total activities and quantities can become negative if you reverse more than was previously backflushed because no reference existed to the document.
