Supplier not showing up in Purchase order

[Dhananjay Katre]

Hi,

---Supplier not showing up on purchase order screen.

Following is the scenario.

I have created requirements for a product with productID say 1002

For my product, I have already created a supplier and also have supplier product ID.  For my product store also, I have assigned the role of supplier to the same supplier party. 

Then I created requirements of type "PRODUCT REQUIREMENT" for my product. From the requirements, I created a purchase order. The purchase order gets created successfully. However, the value of the "supplier" is shown as blank.  I found that the party with id "_NA_" is getting added as the party which ships. 

I have even added my supplier as a carrier with three shipment methods.  

Even though I create a purchase order directly (i.e. not through the requirements), even in that case, my supplier is not getting shown in the purchase order screen. I am attaching the screen shot of the PO screen in which we can see that the supplier is not shown.

Is there any specific configuration that I am missing?
