MRP 2 cannot raise SAP generated PO

Post by Keymaster001 » Wed Oct 15, 2014 1:32 am

Have semi-finished goods material A and set procurement type for material A to "X" in MRP 2 but this resulted to SAP not being able to generate PO for the components of material A. Our purchasing would like to have SAP generated PO for both material A and its components. Is this possible? How could I set this up?

Not sure but you can play around by specifying a Special Procurement key.

Good luck,

Special procurement type
Allows you to define the procurement type more exactly. The system determines the procurement type from the material type.

Use
You use special procurement when you want to be able to override the procurement type in the material master or define the procurement type more precisely.

If the procurement type is in-house, you can nevertheless force the system to ignore the BOM and routing, and process the material as if it were externally procured, by specifying the special procurement as external.

Procedure
Enter the special procurement type to which you want to restrict the selection.

Example
If you procure a material externally, you may want to choose the special procurement type Consignment. If you produce the material in-house, it may be appropriate to choose Production in other plant.

Dependencies
If a material has a routing but no BOM, it is treated as an externally procured material even if the procurement type is in-house. Both the BOM and the routing are ignored.

However, if you specify the special procurement type as in-house, the routing is included even if the material has no BOM.

Did you ask WHY your purchasing department wants a PO for the intermediate as well as for its components?

Is this subcontracting - i.e. you buy the components and then send these to a subcontractor, and then "buy" the service to convert your components into your intermediate product? If so, use special procurement key 30.

If your intermediate is optionally made in-house or purchased externally, if you ask MRP to plan to exclusively buy rather than make the intermediate, then it will NOT requisition the components - which makes perfect sense. You can set up a mix of make/buy at the intermediate product level using a quota arrangement; if you do that MRP will propose to buy components for the proportion of the intermediate you plan to make in this mix, but not of course for the portion you plan to buy.

If you intermediate has procurement type X and you have a valid BOM & production version consistent with your lot-sizing parameters, MRP should be generating a planned order for the intermediate and purchase requisitions for the components, and you should be able to take the planned order and create a purchase order from it if you choose to buy rather than make the intermediate (in which case, the next MRP run will clear out the component PRs).

Hi,

The procurement type ''X'' being set for material A does not have any impact onto if the material A's component can be purchased externally. What was the error message did you receive when you tried to create PO for material A's component? What was the procurement type being set for material A's component?

Cheers,
HT

Actually there is no error, our is that PurReq is not automatically raised by the system when we set the procurement type to "X".

'X' means that procurement can be external or internal. How would you expect MRP to know that you want a purchase requisition??? If you want a requisition, set the procurement type (or special procurement) to external procurement.
Good luck!
