Source Determination Function in MRP

Can someone please tell me the function module MRP uses to do source determination for materials? this would be the function that first looks for a quota arrangements for the material and plant, then the source list, etc...

Best Regards
Though very late, but I hope you serve.

Source determination,Quota Arrangement Process

Hi,
Plz tell me how to maintain Source determination,Quota Arrangement.step by step

Dear,
QUOTA ARRANGEMENTS
If a quota arrangement exists for a material, it has the highest priority during source determination. Like source list, the quota arrangement facilitates the administration of sources of supply at plant level.
If you procure a material from different suppliers, you can assign a quota to each individual supplier. A quota arrangement applies to a certain period and specifies how the receipts should be distributed among each source of supply.
If a quota arrangement exists, this does not mean that the quantity of a single manually created purchase requisition is automatically apportioned among different sources. In such case, the entire quantity of the requisition is assigned to one source u2013 the source that is next in line receive the relevant order.
Before you can maintain a quota arrangement item with the procurement type external procurement, a source of supply (info record and / or outline agreement) must exists.
Create quota arrangement:
LOGISTICS u2013MATERIAL MANAGEMENT u2013 PURCHASING u2013 MASTER DATA u2013 QUOTA ARRANGEMNET u2013 MAINTAIN.
Specify number ranges for quota arrangement:
SAP IMG u2013 MATERIAL MANAGEMENT u2013 PURCHASING u2013 QUOTA ARRANGEMENT u2013 DEFINE NUMBER RANGES.
You must specify the business application for which quotation arrangement will be used, for example: in material planning or in purchase requisitions. You make this specification in QUOTA ARRANGEMENT USAGE filed, which is to be found in the plant-specific purchasing/materials planning data of the material master record.
Set quota arrangement usage indicator:
SAP IMG u2013 MATERIALS MANAGEMENT u2013 PURCHASING u2013 QUOTA ARRANGEMENT u2013 DEFINE QUOTA ARRANGEMENT USAGE.
System assign quota rating to each source by calculation as u2013 Quota rating = (quota allocated quantity + quota base quantity / quota).
ADDITIONAL ASPECTS OF SUPPLY SOURCE DETERMINATION
Quota arrangements also can be source of supply.
Quota arrangements for material requirements arising over a certain period divided up among different sources on basis of quota. Quota arrangements determine which source of supply is automatically assigned to a purchase requisition.
SOURCE DETERMINATION
The purpose of the source determination process is to automatically assign a source of supply to a purchase requisition, if source determination indicator set in the requisition header, the system searches for possible sources of supply for all the items of the requisition. Quota arrangements also can be source of supply.
In source list specify a preferred source as fixed for a certain period, the system suggest just only this source, even if other potential sources exists.
Quota arrangements for material requirements arising over a certain period divided up among different sources on basis of quota. Quota arrangements determine which source of supply is automatically assigned to a purchase requisition.
Source list record consists of the following:
1.Validity period u2013 Period of validity
2.Key source data u2013 Number of vendor and responsible purchasing organization or number and item of outline agreement.
3.Fixed source u2013 Within a validity period not more than one source should be flagged as fixed.
4.Procurement plant u2013 if the materials can be procured from a plant or another point within your firm, enter the plant number in PPl field and leave the field for the vendor number empty.
5.Blocked source u2013 To block a source. If you set Blocked indicator and enter only one validity period, the material is excluded from external procurement; that is, it cannot be ordered during this period.
6.Material requirements planning - You use MRP indicator to determine whether an automatic source determination process is carried out during the requirements planning run. The appropriate source is then automatically assigned to a purchase requisition, or scheduling agreement delivery schedule lines can be generated directly via planning run.
If an attempt is made to order a material subject to a source list requirement from a source that is not included in the source list, the standard system issues an error message with the text: Source not included in list despite source list requirement. You can change this to warning message.
If source list requirement defined for a plant, all materials in the plant level must be maintained with source list before procurement.
Analyze source list:
LOGISTICS u2013 MATERIAL MANAGEMNET u2013 PURCHASING u2013 MASTER DATA u2013 SOURCE LIST u2013 FOLLOW ON FUNCTIONS u2013 ANALYSE.
Define source list requirement at plant level:
SAP IMG u2013 MM u2013 PURCHSING u2013 SOURCE LIST u2013 DEFINE SOURCE LIST AT PLANT LEVEL.
Source lists can be created:
-Manually.
-Create from within an outline agreement u2013 on outline agreement overview screen, select an item for which you wish to enter source list record and choose ITEM u2013 MAINTAIN SOURCE LIST.
-Creation from with an info record u2013 you can enter vendor in the source list when creating or changing a purchasing info record. Choose EXTRAS u2013 SOURCE LIST. If the info record valid for entire purchase organization, you can create the source list for all plants of the organization in question. Choose the plant via GOTO u2013 PLANT.
-Automatic u2013 can generate by system automatically.
Create source list manually:
LOGISTICS u2013 MATERIAL MANAGEMENT u2013 PURCHASING u2013 MASTER DATA u2013 SOURCE LIST u2013 MAINTAIN/DISPLAY.
Generate source list automatically:
LOGISTICS u2013 MATERIAL MANAGEMENT u2013 PURCHASING u2013 MASTER DATA u2013 SOURCE LIST u2013 FOLOW ON FUNCTIONS u2013 GENERATE.

Source Determination for contracts via ME25

Hi All,
We are using ME25 to create PO's. During source determination, a
contract that is valid on the delivery date but not on the current date
is not suggested as a possible source of supply though it has been
maintained in the source list.
We know that this is programmed this way.Check is always carried on the
basis of current date. Though the delivery date falls within the
contract validity date, the system does not suggest the contract as a
source since the validity of that contract has not yet started or it is
not matching with the current date.
But we want the system to suggest the contracts as a source of supply,
though the validity of the contract has not yet started. we want the
system to suggest the contracts which are not valid on current date(but
valid on a particular delivery date) also.
SAP notes 44368 and 427864 suggest that this can be achieved.The note
427864 also tells that "selection with a date other than the current
date could lead to problems (for example in case of MRP runs).With the
corrections of Note 44368 you can solve the problem".
It also says as below:
"The attached correction instruction solves the problem described in
this note. However, these corrections might lead to other problems.
Therefore these corrections are not implemented in the standard system."
It says it might lead to other problems also. But it didn't mention the
exact problems.It would be great if you can list out the MRP run and
other problems and suggest us.
We want this functionality. One more note 116464 is also related to
this. Suggest us which are the notes to be applied. We are currently
using SAP 4.7 Version.
Thanks in advance.
Warm regards,
Shankar Goud.

Hi,
I am not sure that there will be any problems by changing this if you do it the way that the note indicates. I would suggest that SAP are quite right to effectively say "We have designed our system to use the current date, if you want to use anything else then you MAY have problems" (because effectively this is what they are saying).
It is a heavily integrated system and changes like this can cause unforeseen problems, but if you are going to test it thoroughly then it SHOULD be OK.
I would agree with SAP in that it is far better to NOT make this change, but if you really need to do this as part of your business process then you may have no other choice.
Have you thought of bringing the date of the contracts forward to the current date when they are created and controlling their use by setting the source list dates to the dates you want them to be used? This may not work and it too is a scary change but it might be worth having a play with it in your sandbox system (also set the source list as mandatory on the material master if you want to stop manual POs from being allocated too early).
So I guess I am saying go ahead if you have to but beware the warnings (even though they may be unfounded).

Source determination not happening during PR creation from Planned order

Hi Experts
We have set up source determination and we have created a sourcelist of material and a vendor is fixed, there is a inforecord alos maintined,
I am trying to convert a planned order from MD04 to a purchase requisition, the source is not being assigned for the PR, I am alos getting an information saying that 'the material is defined for inhouse production'
secondly if I click the 'Assign Source of Supply', then I am getting an error 'not possible to assign a source of supply'.
The material is a finished material 'FERT' with procurement key 'X' so in MRP an planned order gets generated for converting a PR or a production order.
Note - I was doing this effectively in a differnt client without any proble. I am unable to find what I am missing, please sugest.

Nagaraj Chaganti wrote:
Thank you everyone for the suggestions, The issue is resolved by testing with a new material with tproper master data. Basically the problem occured when some user created additional inforecord for the same P,Org hence there was no automatic source detemination happening.

a second info record may explain that AUTOMATIC source determination ddid not work but it does not explain the error messagees you described earlier.

What is the use of Source Partner function

Dear Experts,
Can you please explain me the exact use of Source Partner Function in Partner Functions in procedures in Customizing.
Is it used to propose only sold to party partner function or any partner function from the master data of particular partner function.
I read SAP standard help but I got confused because of its example. It is as below.
Source partner function
Partner function which serves as an alternative source for determining the sold-to party.
Procedure
If you don't want the system to propose a partner from the sold-to party master record, enter another partner function here. The system will then propose the sold-to party from the master record of your partner function.
Example
If you enter WE (ship-to party) in this field for the function VE (sales employee), when you create the sales document, it determines the sold-to party from the VE partner function in the ship-to party's master document.
kindly reply. thanks in advance
sagar wagh

Dear Sagar,
While determining the partner functions you can define that particular partner should be determined from the source partner functions master data.
For example you want to determine the Freight forwarder and you want to make sure that this partner function should be proposed as per the ship to party then in customizing for freight forwarder partner function you will maintain the source as ship to party. Due to this customization when you will be creating the sales order for sold to party x and assume that for x you are having two different ship to party at two distinct locations. For these two locations you have different freight forwarder providing the services(one for each location). So to determine the right freight forwarder the above mentioned customizing will be required. Otherwise system will propose this partner function as per sold to and that will be same for all ship to.
Hope this example will help you to understand the usage of source in partner determination.
Thanks and regards,
Atul

URGENT PLEASE HELP - Source determination in Limits Carts not working

Dear all,
We have implemented SRM 4 on Server 5.0 and ECC 5 backend.
We have in our environment service masters that have been catalogued and linked to Contracts. When one raises a cart and selects one on these catalogue service items, a backend PO correctly creates and references the contract as specified in the catalog.
The problem we have discovered that if we raise a Limits order and specify the material group stipulated in the contract for a service, source determination fails to "pick up" this contract line. We are forced to enter a supplier all the time!
Also if we raise a text service line and select from "internal Goods/Services" a Service Master record and add it tothe cart, surce determination also does not pick up the R3 contract/line that matched this service. This means that when POs are created in the backend, they are not referencing any contract (no call-off)
Why is this happening? How come catalogue items linked to a service masters and contracts work and correctly and a Limits order do not?
Please help, we need to resolve this issue today.
Thanks,
Grace.

Hi Grace,
The contracts that are created in SRM can only be refered as Source of supplies while creating shopping carts if your are working in Extended Classic scenario.
In case you want to refer the back end contracts, Info. records for creating shopping carts you have to implement classic scenario.
The standard SRM does not provide the functionality you needed where as if you want to use back end contracts for a particular product category you can implement "Controlled Extended Classic Scenario BADI " which makes the classic scenario active for that product category, there by a back end contract can be referred for that product category when ever a shopping cart is made.
Hope this makes you clear. Clarifications are welcome.
Award points for suitable replies.

Automatic Source Determination

Hello,
I have implemented function module exit EXIT_SAPLMEREQ_005 of enhancement MEREQ001 to control user input, one of which is the desired vendor field. Under standard system conditions, if the user enters a desired vendor then automatic source determination is ignored. The exit implemented clears this entry. I'm successfull with this strategy so far.
Now that I have the field cleared, I was hoping that automatic source determination would take over. Unfortunately, it seems this is executed (or would have been) before my exit. I want to execute the procedure again after clearing the desired vendor. Do you know the function module, or something, that will do this for me?
Thanks
C

Thank you for your reply! Your suggestion led me to ME_SEARCH_SOURCE_OF_SUPPLY. A break-point in this function module proved to me that this is the one being executed. This function requires VALUE(COMIN) LIKE BQPIM STRUCTURE BQPIM.
The function module exit I am implementing, EXIT_SAPLMEREQ_005 of enhancement MEREQ001, only includes data from MEREQ_ITEM, which is only line item data. Not all of the information required to build a structure like BQPIM is available, such as header data like document type and document category.
Where can I get all of the data I need to make the call to ME_SEARCH_SOURCE_OF_SUPPLY? Any suggestions is greatly appreciated.
Thanks,

Source determination of agreement which used SC vendor.

Need to deliver to vendor B when purchasing one item on agreement 4601001470 from vendor A.
The user tried ticking the SC vendor checkbox on the delivery tab for each item in the agreement and also entered vendor B. This did not work. When the tickbox is checked and SC vendor number entered the agreement details do not autopopulate into the requisition. It is also then not possible to manually assign the source of supply in the requisition. we can't get source determination to work on this material, even though the contract and source list looks OK.
If anybody have solution,Please help me.Thanks.

Have you done PIR on Subcontract Info category for Vendor B.?
Check Source list for Vendor B maintiaed or not.
Try 1 : Give the Vendor B ( Subcontractor ) In te out line document by following the path
Seelct the line in O.A go to Item -
> more function -
> Delivery Address, you will get the pop up, where you can maintain the Subcontact vendor with tick.
Try 2 : By fixing the vendor in SOuce list
Let me know if still problem is there.?

LMEQR001- Source Determination Exit, Sample Code

Dear Experts,
We have a situation where the source determination should be assigned automatically in the Requisition. Currently SAP Standard functionality works only if user enters all the information correctly. If user changes the material number( A to B), it does not determine the source of supply automatically.
I believe, exit LMEQR001 can be used to fulfill the above requirements. Appreciate, if any one can provide the sample code to achieve the same.
Points will be rewarded
Looking forward to hear positive response from your end.

SAP Automatic source determination

Dear Gurus
I have a source list with one vendor (with fixed indicator and "1" relevant for MRP).
Further, I have a info record for the same material vendor combination.
Validity period is until 31.12.9999.
But system is not picking up the vendor for purchase requisition, after MRP run.
Is there any specific reason for that?
Thanks & Best Regards
Rupesh

Hi,
Go to OMFI - Here create a key or use 01 by making necessary changes as following;
Under Source Determination Tab Page, activate "Create Requisition" and Save.
Then go to the User Master (SU01) of the MRP Person and under "Parameters" Tab Page, maintain this key "01" against Parameter ID "EVO" and try MRP Run again and check.

Supply source determination

what is meaning of supply source determination, how it works purchase price determinations sequence used in the calculation of sales price, Please explain me what is source determination and purchase price dterminatiion type whcih are used in sales price calculation.

Hi Madhuri,
The sales price calculation function contains three subfunctions:
       1.      Determining the purchase price (purchase price determination)
       2.      Determining the sales price (sales price determination)
       3.      Determining the margin, or the actual markup
So your question is about the first step i.e Purchase Price Determination
To determine the sales price of an article which is determined based on the purchase price of the articles ( markup), the purchase price of the article needs to be determined first.
Supply Source Determination
An article in a store can be procured from a DC or from a vendor. This is differentiated by using the "Supply source" which is in the Article Master - Store (or DC) view ( Field Name: MARC-BWSCL).
So when you enter a sales organisation and distribution channel in the VKP5 screen for Sales price calculation, the supply source needs to be found out first to find who is the supplier. The site for determining the supply source is based on the reference site that is assigned for every distribution chain ( Sales org + Dist Channel) and the Sales OrgDist ChannelPrice List
This configuration of assigning the reference site to the dist chain is in
Logistics general -> Retail Pricing ->Sales Price Calculation ->Assign Pricing Type/Reference Site to Organisation level
So once the reference site is determined the supply source of the article can be determined from that store. Then once it is done using the source determination of checking the
1. source list for the store/DC,
2. Supply Region
3. Regular vendor
etc then vendor will be identified ( the sequence may not be correct). Please refer to the below link for more detail on the source determination.
http://help.sap.com/saphelp_erp60_sp/helpdata/en/32/fa424287cf9923e10000000a155106/frameset.htm
Once this is done, now we know the cost of the article ( PB00) but we need to find the purchace schema.
The standard purchase price determination sequence is based on the Vendor Schema Group + Purchase Organisation ( Porg Schema group ) if its an external vendor else the STO schema will be determined. Once the Net purchase price is determined through the purchase price, this is used for determination of the sales price using the another process of sales price determination sequence.
Hope this clarifies your query.

Prabhu

Source determination with referance to quota arrangement

Dear all
I had created quota for vendor A & Vendor B for a material M100, I had also defined quota arrangement usage in SPRO ( 3),
While creation of PR for this material M100, I had selected the tick for source determination, But still system is not determining the source.
Here one more observation is if I create the info record the source is determined from info record & the details are updated in quota.
Can some one help me which other things I need to check, so that the source is automatically determined by system from quota arrangement.
Thanks in advance
Regards
Pravin

HI,
If MIGO is done for the P.O all the datas are updated in the Purchase order history.
When you are doing MIRO , it will take what you have entered in the MIGO only.

Need help in source determination.

Hi
There is a source list maintained for a material and plant comibination. This list contains the Agrements along with the vendors.
Now the quesion is how the system will use this for source determination?
IS there any T-Code to analyze the source list and find a appropriate vendor?
Any other records, documents which system will consider while source determination.
Your help will be highly appreciated.
Thanks in Advance
Nageswara.

Dear Nageswara,
First understand the importance of sorce list. it is used to restrict the number of suppliers. It means that if you don't maintain the supplier in the source list you can not procure the material form that supplier if you have activated the source list for that material .
your source of supplier can be anything i.e. it may be external vendor or another plant or outline aggrements.
while creating the PR or PO system will ask for source of supply. here you can choose any of the supplier which is maintained in the source list.
There is T-code as ME01 for maintaing the source list.
Thanks and Regards

Source Determination for Service PR

Hi Experts,
One of our clients requirement is in their Procurement process, they want to create Service PR (material group, text) with Item category D and Acc Assignment as K. They want the system to determine the Source of supply automatically. When we check the source determination check box- but the system is unable to determine the source.
They want to remove manual intervention. If the source is determined in PR, it will be converted to PO. Please assist.
Thank you,
Surendra

Dear Surendra,
This is to let you know that, there is no provision to maintain source list for services as we do for materials.
Suggestion A:
Since there is no provision to maintain the source list for services, follow the steps, which are explained by AKPT M . Sure it would help you, if not check out the other two suggestions, given below.
Suggestion B:
If you would like to have automatic procurement process as material procurement, better follow the below steps;
Create a material with material type DIEN
Maintain the source list
Create a PO for the service material
Create MIGO document
Note: As you are procuring services through material master, there is no involvement of Service Entry Sheet and the services will be directly posted to consumption account.
Suggestion C:
Try with 'Standard Service Catalog - ML01
Thanks & Regards,
