purchaser cannot able to see purchase orders in the worklist

Hi all,

I am working on SRM 5.0 SP 10 and i have an issue related to PO.

I cannot able to see the created purchase orders from the purchasers view.

I have assigned the user organization in the responsibility tab of the purchaser.

I have assigned the product category in the responsibility tab of the purchaser.

Can any body suggest me what are required changes to see all purchase orders.

Thanks,

mahesh
