Mis match in attributes of item category B-limit and PO item details

Hi

I could not able to create a Blanket PO with document type FO and item category B (limit).

Normally for a blanket PO, GR is not allowed and IR is mandatory. So, I could able to see these checkboxes for GR (not set and grayed) and IR (set and grayed) in the item details of the PO in delivery and invoice tabs. But I end with an error message that 'GR is not set is used is not allowed' (exactly i don't remember but some thing like that)

Before creating a blanket PO, I found that in 'attributes of item categories', that for the item category B, GR is set and IR is not set (in customizing-OMH4). Of course, one cannot change the attributes of item categories.

I suppose due to this mis-match in the attributes of item categories and that in the PO, I'm getting an error message while creating a blanket PO and could not able to save.

Also I have checked all the system messages for the message displayed. No where(i.e. in any message class or category and for that message number) I found any such message defined with error in 'attributes of system messages' for purchasing, material master, inventory, invoice verification etc.

I suppose this error message is coming somewhere from the application program for the PO.

So, what can be the solution

waiting for your reply.

thank you
