Hi Gerardo,
Great that Srinu has mentioned the option from a Transaction Point of view which should work.
If you are wanting to do it forever then, you might have to change the Incompletion Procedure for the Schedule Line which is possible.
I am not sure what your real intent is but if you are inclined to pursue this line of thought, then read on :
Option # I] :
1) Create a New Incompletion Procedure for the Schedule Line through T. Code : OVA2 with whatever fields you want to have in the Schedule Line as applicable as Incomplete;
2) Assign the New Procedure to the Schedule Line through T. Code: VUE2
Should be simple enough.
Option # II] :
Remove the Incompletion Procedure through T. Code : VUE2 from CS Schedule Line.
By the way, what is Standard SAP is there for a reason.You do not want to confirm to the Vendor your PR based on a Order from the Customer who is already over his head with respect to Credit Limit.
There is always an individual discretion of releasing a block and letting the order be confirmed with the creation of the PR to vendor.
Thanks.
