Trigger availability check in delivery document
I would like to trigger a new availability check in delivery when the document is saved.
In my scenario the user deletes the delivery block (block for pick and GI) in the header data.
When the delivery block is deleted, a new ATP is needed in order to confirm again the quantity in the document.
The new check should be the same already triggered by the system when the storage location is changed.
I can use also user exit but i don't know what is the correct one.
Someone has a suggestion for me?
Please help me.
