ATP for sales orders
Does anybody know how to switch off ATP ONLY for Sales Orders?
Customer would like to have ATP for deliveries, but not for sales orders. This means whatever delivery date will be entered during SO creation, system will accept it without ATP. On the other hand if there is nothing on stock system should create delivery with "delivered qty" = 0
The only transaction which connects ATP type (02 in this case) with checking rule (here: A- Sales order) is OVZ9. But I cannot switch off ATP there. I can only define different settings for sales order and delivery.
If I change settings in OVZ0, then it will switch off ATP for both: sales order and delivery
Customer has only one requirement class ZXX, so in OVZ) I can switch off ATP, but unfrotunatelly for both (sales order and delivery).
In standard I see requirement type 031 (Order requirements) and 011 (Delivery requirement), so I think this is the way I should go.
I've checked SPRO here:
Availability Check and Transfer of Requirement --> Transfer of Requirements --> Determination of Requiremenr Types Using Transaction.
The problem is that for one item category I can assign only one requirement type (ZXX in this case).
How do I switch off ATP only for sales orders?
Is it possible?
