SAP MM- Source List/PR/Quota Arrangement/PO with Business Ex

Description

Here I tried to explain deep explanation regarding Source list/Quota/PR/PO

PR is an internal document, where requisition will be created as per the needs in the plant by the stake holders (Non-Purchasing department). Whereas PO is an eternal document, where a document will be sent out of department to the vendor to procure goods to fulfil our production.

Some of the mandatory fields to create a PR are Material, plant, vendor, Purchase organization. And for PO we can create without reference of PR also, but this is against the procurement policies.

t-code to create the purchase requisition is ME51N followed by ME52N, ME53N.

t-code to create the purchase order is ME21N followed by ME22N, ME23N.

PO Order for pulling reports: ME2M, ME2L

while creating PR, price will be automatically taken from Material master, we will maintain valuation price as S or V, whatever we maintain in Material master it will be pulled to purchase requisition.

Eg: If we maintain Standard price and moving price in the Material master, then which UOM will be taken in the PR?

We are maintaining the valuation type as-S or V, so price will be decided by the S or V.

Order Unit of Measurement:

Order unit is the vendor Unit of measurement, where we need to send the external document to the vendor for procuring goods from them, so we need to order as per there UOM, so we have order unit of measurement.

1st scenario: When we are creating PO, UOM will be pulled from material master, Order unit and if there is No order unit is maintained then PO will automatically take from Base unit of measurement (This is the case without PIR)

Variable UOM in material master

Variable unit will be additional unit maintained in the material master, where we will maintain the conversion for that order unit.

Eg: if we want to maintain Box as an alternate unit for order unit PC, then we need to maintain 1 BOX is equal to 10 PC, so that while creating PO we can change as per our requirements.

We need to maintain the variable UOM to 1(Active)

UOM in PO

If there is no PIR, then PO automatically takes from Material master Order unit

If there is no order unit maintained, then PO will take Base unit of measurement in PO.

If there is PIR, then priority is PIR and then Remaining.
