Requistion and Purchase Order - base unit and order unit

[Former Member]

People,

I have a basic doubt in MM:

I have a Requisition with a item using the base unit, for instance 20 litres.

When I create a Purchase Order in ME21N passing the requisition and item number, I must be converted to the order unit, correct?

In this case, we have 1 UN (order unit) corresponds to 20Liters (base unit).

I did believe the Purchase would be converted to 1 UN, but I got 20 Liters.

What is correct?

Thanks a lot!

If you maintian the order unit in the mateiral master purchaisng screen than whenever you create the PO system will convenrt in to that order unit and in the Po item details you will see the conversion of base unit to order unit.

now suppose you have more than one order unit than you activate the Variable order unit in the material master and maintiqan the conversion of that and create the diff info record for diff order unit based on the vendor so whne oyu create the PO as per the vendor system will pull the order unit in the PO.

Hope this will give you clear picture.

For Pur.Reqs if you reference an already existing material number, the system will use the base unit from the material master record. If Purchasing is to order the material in a different order unit, you can specify this on the detail screen of the purchase requisition item.

For PO, the order unit is taken either from Material master record or Info record
