When we open the PO Entry dashboard, and search for the PO number, we can see that this PO is generated from Purchase Requisition (PR). Similarly, Purchase Requsition Entry dashboard, when we key in the PR no. we can see the PO number as well. Both are linked and we can know that this particular PO is generated from PR. HOWEVER, there is no indication on whether is generated from PO Suggestion/MRP.

Same goes to JO Entry dashboard, we can only see JO number and other details but no indication of whether this JO is generated from JO Suggestion/MRP.

In conclusion, Requisition Entry (PR) and PO Entry can linked each other.  PO / JO suggestion and PO / JO Entry unable to linked each other – no where to check if the PO / JO entry is created from PO / JO suggestion
