Purchasing :Reason for Ordering (We miss the Retail Tab in PO Items)

Dear All,

I configured reason for ordering in SPRO. I made reason for ordering as optional in SPRO->Materials Management->Purchasing->Purchase Order->Define Screen Layout at Document Level.i.e. in adminstrative data item .

When I create a Purchase order I can not use reason for ordering becuase I do not have the Retail Tab in PO Items.

How to solve this problem?

I need to active the Retail Tab in the purchase order to be able to see the field Reason for ordering.

We are not allowed to active the business function IS-Retail. T.code SFW5

Please advise!

Thank you in advance.

Regards, Zaid
