Hi,
There is no standard authorization object that you can use from
transaction ME21N to validate the cost center that you see in the
account assignment view at item level. The same can be said about the
Purchase Requisition creation in transaction ME51N.
First option:
There is an existing possibility to perform user defined checks during
all kinds of postings which finally lead costs in CO. With transaction
OKC7 , you may define a validation which is also processed during
purchasing. You can explore the possibility of achieving the
functionality you need by making customizing changes using transaction
OKC7.
Second Option:
You could use User Exit Enhancement MEREQ001. For further information ,
please check
SAP Note 310154 - ME21N/ME51N: Customer-specific check, generating
Third Option:
Instead of an authorization check for cost centers , you can activate
an authorization check for G/L accounts.
Therefore , the following settings are required:
I. Customizing -> Materials Management -> Purchasing -> Purchase
Order -> Set Up Authorization Check for G/L Accounts:
activate the G/L account authorization check for the required
company code
II. Transaction FS02 -> View: Control data: enter the authorization
group
