GATP-CRM, ATP check is called, but doesn't get saved in the sales order

Question

Hi ,
We have integrated CRM with APO t do ATP check. We are using rule based availablity check.
Under rule based check we are using location determination procedure.
Our scenario is sales from Stock.
Following example
Example:In our case SKu1 stoick is present in location A & B.
Stock in A: 1000
Stock in B: 500
When we create a sales order in CRM of quantity 1000, ATP check is called and the 1000 qty gets confirmed and can successfully save this order..
The ATP works fine in this case.
But if the order exceeds than the stock present in any one of the plant we face following problem:
Sales order qty is 1500:
the availalibilty check is done, qty confirmed from A:1000 & B is 500.
But when we save this order, the confirmed qty becomes zero.
Need your suggestions on this.
Regards,
Chetana

Answer 1

When you are in the APO-Avail check screen, as described you will see that both 1000 from plant A and 500 from plant B is visible, However can you check to see if the CUMULATED CONFIRMED QTY is 1500 or 0
From your description, looks like it is 0 because of which the confirmation is 0 qty
To solve this, please check the following and do one at a time and see which one works
(1) ATP GROUP in APO----- Change CUMULATION to """"CUMULATIONN OF CONFIRMED QTY"""""""
If this does not work, check the CHECK INSTRUCTIONS
(2) in check instructions under RBATP--- check the box for "" Create SUB ITEM"""
Please post us which one worked as it will be helpful for others in the future
Thanks
