ATP negative

[Former Member]

Hello,

I have problem here with ATP negative. I can see this information on transaction CO09.

The following steps was done to generate it:

Available stock before steps = 10 UN.

Step 1 - Create sales order 1 with 8 UN

Create sales order 2 with 2 UN

Create sales order 3 with 2 UN

ATP = 0

Sales order 1 confirmed = 8 UN

Sales order 2 confirmed = 2 UN

Sales order 3 confirmed = 0

Step 2 - Include Reason for Rejection on sales order 2

Execute transaction V_V2 (you can do it on VA02 too)

ATP = 0

Sales order 1 confirmed = 8 UN

Sales order 2 confirmed = 0

Sales order 3 confirmed = 2 UN

Step 3 - Remove Reason for Rejection on sales order 2

ATP = -2 (negative)

Sales order 1 confirmed = 8 UN

Sales order 2 confirmed = 2 UN

Sales order 3 confirmed = 2 UN

Did anybody have the same problem and coul solve it.

Thanks in advace.

Run program SDRQCR21 in SA38 and check the results again. Also take a look at OSS Note 1170146 - co06 Overconfirmation possible with parallel va01 sessions. There are few other notes with ATP Negative, and you can look into those if the above note does not address your issue.
