Unable to search BPA at enter requisition lines.

Summary:

We are facing an issue where we are unable to search for an item in the shop by category area during requisition creation, even though the item is enabled as Purchased and Purchasable in the Item master.

Additionally, we have created a BPA for the items. However, when we attempt to search for the BPA in the enter requisition lines area, the system does not show any BPA at the agreement area.

could you please help us understand why the Item is not visible under shop by category and why BPA is not coming in the enter requisition line level.
