avoid further changes in requisition once converted to PO

[marcoantonio_romerosanche]

Hello..

I have a question....

It is possible to avoid further changes in requisition once converted into a PO??

I know that I can controll that via authorization by removing the ME52/ME52N transaction.. but I want to know if there is a way to control that via customizing?

I guess you dont understand me.

This actual scenario is:

1.- Requestor create a requisition with item 10

2.- Buyer convert it to PO

3.- Requestor use same requisition number and create a new line item 20.

This is the scenario we want:

1.- Requestor create a requisition with item 10

2.- Buyer convert it to PO

3.- Requestor use same requisition number and create a new line item 20 when try to save, the system must sent a error. o System must not allow to create more line items.

Sorry i did not read your full query

the solution you are looking is not possible with std SAP

to acheive this solution please use the PR user exit MEREQ001

here add your logic and activate this user exit.

This is Not Possible thru Standard SAP.

You Can Control PR Line Items for Further Processings but You Cannot Control Users to add New Line items in PR.

Try the Following Enhancement on PR

MEREQ001 Customers' Own Data in Purchase Requisition

You can use this enhancement to:

o Maintain/supply your own customer fields in purchase requisitions

o Update your own customer-specific tables

o Change standard fields to a limited extent

Im.. I tried by adding both messages and create new requisition and new PO.. but when I go to ME52 and create a new line item.. nothing happened. System allow me to save the requisition with line item 20.

Does that will apply for the existing line item.. correct?

I mean to avoid changes in the whole requisition... to avoid to add a new line item.

Yes, you try it once.

Hi,

Go to SPRO > MM > Purchasing > Environment Data > Define Attributes of System Messages > System messages > Here make following Messages as Error;

06 152 (Purchase orders already exist for this item)

06 648 (Requisition quantity already ordered in full (see follow-on docs.))

Hai,

1.This you can control thro' Release procedure for PR.

2.In the Release procedure configuration once the PR is released, then via changebility indicator 1 - Can't be changed for the release indicator 2 RFQ/purchase order, you can restrict the user to ammend the same PR with new line item also.
