Costing with quota management

[jan_turek]

We have the quota management active in the material master for certain component. The procurement type is F, Special procurement 30. The quota actually exists (say 2 vendors with split 70%/30%). When costing from configuration (CU50) the system seems to select vendors "randomly" from these 2 vendors in quota arrangement when we are running the calculation several times one after one. I am not sure about the standard functionality. Does SAP record the quota usage during the calculation so that if we repeat the calculation e.g. a minute later the other vendor is selected because the first one has already run out of its quota? Does this happen even though the calculation is not saved?

Can you please explain how the quota arrangemed is exactly handled in costing?

thanks to all

Jan,

You can choose source of supply or Vendor based on actual quota or planning quota indicator for costing.

Check your valuation variant and see what strategy is defined in Sub Contracting there. 

Check t-code ME57 and MEQ3 the quota arrangement, Quantity and periods,

Go to these links it will be clear to you about quota arrangement in SAP.

Hi Hrusikesh,

Thanks for useful links. Now I have the idea on how a vendor is selected in case of quota arrangemenet. The thing I wanted to clear to myself is how the quota usage is recorded in a calculation. Users complain that they are getting differrent price (almost) any time the run CK11N, CU50 etc. My explanation is that when a material with quota arrangement is costed, the quota usage is "remembered" (like in MRP) so that the next calculation of the same material takes another vendor. An example: we have 2 vendors in QA, both with a maximum of 5 pcs. When I run the calculation for the first time for 4 pcs, say the 1st. vendor is selected. When I run the same calculation again also for 5 pcs , there is only 1 pc remaining available from the 1st. Vendor so that another 4 pcs must be takend from the 2nd. vendor. Is that correct?

Dear Jan Turek,

In my understanding quota arrangement can help the business during Material Requirements

planning to split the requirement quantities as per the quota settings maintained in MEQ1 for the

material.

Quota arrangement describes exactly how the receipts are to be distributed among the various

sources of supply(Source of supply can be a vendor, or another plant or production version etc).

I don't think it can help the business during the standard cost estimate.

But creating procurement alternatives in CK91 and the mixing ratios in CK94, then check the impact

during standard cost estimate.

Dear Mangalraj,

Thanks for your info. Nevertheless, the fact is that for materials with QA (the se have Procurement type F and SOBSL 30) differrent vendors are being selected during costing and these are identical to those listed in QA. So that it appears that QA is effective not only for MRP but also for costing. And this is what users have problem with. They would like to keep using external procurement and QA for MRP but for costuing purpose use always e.g. the MAP (generally the strategy on the Material tab in costing variant).

Check your valuation variant is it based on actual or planning quota arrangement. If it is based on planning quota arrangement yes the prices will be different depends upon your purchase info record information available. Also check what info record its using while calculating standard cost estimate, then check your strategy sequence in valuation variant for sub contacting.

The valuation variant is based on actual quota. Despite this the calculation behaves as described above. if I switch off the quota arrangement in material master then the vendors are no longer being switched.

Not sure what it means to check what inforecord is used - with SOBSL 30 and w/o QA the system should just take the inforecord with the lowest price being valid at the moment of calculation, regardless the vendor and with the cost sequence stated in valuation variant on the tab Subcontracting. This works fine.

Approach as Mangalraj said earlier then by creating procurement alternative in CK91 and mixing ratios in ck94.
