Procurement block exemptions

[Former Member]

hi experts

          we have a requirement like purchase of material should be blocked for purchase all Purchase Order types , except STO Order types.

          For STO orders materials should not be blocked. How can this requirement be addressed.

          Expecting your valuable suggestions.

Hi,

   Go to material master - MRP 2 view and maintain the special procurement key as 40 (STO). Now, maintain the message ME 174 as error message (E) in the path: OLME - Environment Data - Define Attributes of System Messages. Now, system will allow only STO PO for the material. You may test the same and revert back.

Hi all

          In addition to Prasoon answer, i would like to add one more alternative solution blocking of material using source list ME01(Transaction).

You can put complete purchasing block using material status .. but I think it will stop you creating STO too .. so may be you have to do some custom development to achieve this requirement..

create a custom table to maintain materials that are applicable ..then put validation in BADI ME_PROCESS_PO_CUST in item processing method..

But wait for other valueable suggestions before jumping to development.

Go for the user authorization function via SU01. Create user role and assign the allowed transactions here. From the procurement perspective, you need to allow ME27 transaction (Create Stock transport order) and disallow ME21n.

Before trying, you should consult your Basis consultant.
