source assignment through MRP

[Former Member]

Hello All,

when i run the MRP , the requirement must be split among all the possible sources which are maintained in quota arrangement.

but this is not happening even after maintaining the relavent settings .

settings are follows

material master MRP 1 View - lot size ( which is configured with split quoata ) & in purchasing view - quota arrangement usage "4"

quota arrangement is maintained .

source list maintaned with MRP relavent field as "1"

pls suggest what else need to maintain

Hi

Now what exactly are you getting in PR. No vendor? or only one vendor for all required quantities?

If there is no vendor assigned to all PR, you need to check the validity period of info record price, source list and quota arrange ment validity with the quantity delivery date. Is it falling within this?

If all requirement is assigned to one vendor without splitting then you need to check your lot size in OMI4 and tick split quota in long term and shot term planning.

If still you face problem, write to me.

Hi,

My suggestion is try to create a requisition manually for this item and select "assign source" and see what happens, at least this way you will see if the problem is caused by too many sources or none at all being suggested.

or else one final thing to try, are you running the MRP with Plannign mode 1, 2 or 3?

You should try it with 3 so that the requisition is deleted and recreated.

It could be that the system is seeing the existing P req and not recreating it and therefore not checking all of the sources since you have last changed something

Hi

I think all the records are created today only. Do one small change in source list. Start the validity period of source list one week earlier from today and re run MRP.

hi,

When using quota arrangements, every requisition is allocated to only 1 source based on the balance already attributed.

if you want split the requested quantity so that you finally can create 2 orders, then you have to use the lot sizing to do this.

Thanx

HI,

Please check if you have maintained valid dates in validity period of Source List.

If yes then check this,

First you need to have created a Source List/Information Record for all Material/Vendor combinations. To do this, make sure you have an "Information Record" and a "Source List" created. Check the "Fixed source of supply" box for the preferred vendor in your Source List. Now, when you run MPS/MRP, the system will automatically assign the preferred vendor to your purchase requisitions.

If you would like to automatically assign more than one vendor, set up quota arrangements instead of a fixed source of supply.

The system will select the vendor that you chose as the fixed vendor in the source list. If you did not do this, you can assign the vendor yourself. If you are working in an environment where you may have to change the vendor after periodically for some reason (eg. a drop in vendor rating), then you are better off assigning the vendor at the last moment

Regards

KK
