thanks for that. can i just confirm my understanding, I can create PR if there is any deficit stock....

how about if the qty reflect is 2199 in MD04 and 2162 in the PR ? Can you give me a Clear explanation for this?

When would table RESB populated? would this be because of Purchase Requisition transaction. ME53N?

Creating of PR is not block by the stock availability and PR is just a planning Item.

If a user needs some material they can create a reservation or PR based on the design of the SAP system in their client. If user creates a reservation based on the stock and MRP parameters defined in the MRP views system creates a PR if required.

RESB table gets populated only if reservation exists for that material. If the PR/PO is subcontract releated then system creates subcontract requirement/reservation for the components, in that case RESB table is populated.
