SNP Heuristics generates purchase requisition

Hi Experts,
I have a requriement to generates purchase requisitions start date at Monday; Im trying to use period factor but still I gets the reqs still falls in different days and also the planning calendar under the lot-size. Is there any other ways that I can apply this requirement?
My lot-size is weekly bucket and 1 day transportation duration and 1 day GR.
Thanks
Regards,
Lhon

Thanks again for your reply; yes some of the days that didnt fall has holidays for that current week thats why it didnt schedule at the desired date but some of the Preqs generated were fall on other days even without any holidays in the calendar. Except for the calendars of the transport and handling what are the other factors thatc an affect this specified period factor settings? Other than this setting would you consider any other scenario to apply this requirement?

Differentiate between SNP Deployment generated Purchase Requisition in R/3

Hi
We are implementing SNP with Deployment. Purchase Requisitions are being generated from both SNP Heuristic run and Deployment heuristic run and they are transferred to R/3. So using TC MD04 in R/3, we can see both Purchase Requistion coming from the same requirement. We want to convert the Purchase Requisition generated from Deployment to Purchase Order using ME59/ ME59N in the background. Currently, there is no difference between both PReqs in R/3, so system is incorrectly picking up both the PReqs.
It will be great help if anyone can suggest a way to differentiate them in R/3.
Thanks,
Prasun

You can identify PR by category
Category :
EA SNP: PReq SNP: Purchase requisition
EF DEP: PReq Deployment: Purchase requisition
you can use user exit APOCF013 on APO side to put some flag for SNP PR and use the same in R/3.
You need to identify one field in PR data that you can use in R/3 to identify SNP or DEP PR and by user exit you can put flag in that field .
Hope it will help you further.

Mismatched data for "Created By" in generated Purchase Requisitions

Hi,
Just wanted to ask question to all gurus that, I see some mismatched data for ‘created by’ for system generated Purchase requisitions. As if I do MRP run using MD40(MPS scheduling run) then system is showing PR created by 'MRP controller' but if I run MRP using MD41(single item multi level), then system is showing the user ids name(the person on whose id MRP run is executed) is showing in the PR.
As both the MRP runs being executed in the same user id, then there should not be such kind of diffrent data. Due to this mismathced data we are gettting some difficulties in the reporting.
Thanks in advance.

Hi!
It's solved. The mistake was on the connection of the tables:
BUT000 - BUT020 - ADRC

Problem in MRP generated purchase requisition.

Hi Friends,
We have run MRP via MD02 transaction for one material.
MRP generated purchase requisition created.
In that MRP generated purchase requisition, under item level in the status tab we are getting below field values is like below.
Processing status : No edited
Block ID: Blocked by requester.
Due to above values we are not able to convert this MRP PR to PO.
Could you please let us know is there any master setting is cause of this?
Thanks in advance.
Regards
Jegen Mohan

Hi Friends,
After debugging MRP programme, we came to know that there is BADI implemented to block the MRP PR's intially and then z programme called for adding secondary materials/services to that MRP PR's.
After addition of secondary materials/services to MRP PR's, Status will be unblock automatically then save the PR.
This is my client specific scenario.
Thanks & Regards
Mohan.

Min-Max Planning Generating Purchase Requisitions

We have been using min-max planning for a while and scheduling the min-max planning report (planning level: organization) to run every evening to generate a purchase requisition. Of late we have some items that are showing a reorder quantity but not generating a purchase requisition. We have verified the set up of those items against items that are generating a requisition and can't see a difference. What are the possible causes of items not generating a requisition when using min-max planning?
Thank you!

Make sure Item Settup has the "List price" Given.
Source is set to " Supplier"
When you are running the Min-Max Report, it should have the Parameter "ReStock" to "Yes".
Since the records has to come from the Inventory to the Purchasing Module there is possibility that Records might be there in Interface tables. Run the "requisition Import" program and see if it address your issue.
Thanks and regards,

Production order that generate purchase requisition

Hi!
I need to now from where in SPRO I set the purchase requisition type that the system generate when I use MD02 transaction. The thing is that the system generates an NB type, and I would like to generate an PURE type. Can this be done?How?
Also, when I use MD04, and try to convert a purchase requisition (type NB) in purchase order, the system generates an NB Purchase order and not an PUOR Purchase order. Can this be changed, as the system generate a PUOR Purchase order instead of NB, and if yes, where?
Thanks

Hello,
For MRP to create a certain requisition document type, try assigning this to the MRP group for the material in OMDT, so in "doc.type purchase requisitions for standard purchase ord" enter the type you want. Assign the MRP group to the materials appropriate.
Then for a PO type you need to configure settings in MM>Purchaing>PO-->Define document types. Here, for the PO document type assign the correct link to purchase req, meaning only the PO type you want can created from the reqs.
Hope that helps.
Thanks.

Document type for MRP generated Purchase Requisition selection

Hi,
when I run MRP ,for externlal procurement items system is creating Purchase Requisition with Document type NB.How to make system to take different Document type automatically with MRP.
Thanks and Regards
Raghavendra Pai

Dear,
Follow below steps to fullfill your requirements:
1) Go to Tcode OMDT.
2) Click on MRP group
3) In front of your plant maintain your doc.type purchase requisitions for standard purchase ord which you want to generate at the time of MRP --PR generation.
4) Go to Tcode MM02---maintain MRP group same as above parameter in MRP-1 view .
Now run MRP..it will pick the defaulted Document type for PR generation via MRP.

MRP is not generating purchase requisitions consistently for MRP type VB

Issue: When executing consumption based MRP in ECC 6.0 using the following parameters; purchase requisitions are not created for all material with stocks below max stock levels. In other words requisitions are created incase of some materials and requisitions are not created for others.
u2022     MRP type VB ( manual reorder point) with reorder point qty
u2022     Lot size HB with Max stock level
u2022     Procurement type F (external procurement).
Additional info: Some of these materials are batch managed and results are inconsistence whether it is batch managed or not.
Regards
Sai

I checked that and planning file entry is created.
Example 1: MRP is not working.
MRP type = VB
Lot size =HB
Procurement type= F
Material # = 1200045
Reorder point =30
Max stock level = 300
Available qty = 139
No PRs are existing before MRP.
MRP is expected to create PR for qty 161 (300-139= 161)
Example 2 : MRP is working.
MRP type = VB
Lot size =HB
Procurement type= F
Material # = 1200052
Reorder point =100
Max stock level = 1000
Available qty = 87
MRP created PR qty of 913 and results are as expected.
MRP is expected to create PR for qty 161 (1000-87= 913
NOTE: I am directly creating Purchase requisitions by selecting creation Purchase Requisitions Indicator =1 during MD01/MD02 trxs . Not creating any planned orders.

Document type selection for MRP generated Purchase Requisition

Thanks and Regards
Raghavendra Pai

Dear,
Go to SPRO-Materials Management--Purchasing Purchase RequisitionDefine Document types
Copy the NB and create and New Document type
You can default the document type from the MRP group.
Customizing is done in OPPZ transaction.
Once you have entered the MRP group to your material master MRP view, then next MRP run will create the requistions using the document types maintained to the MRP group.
Please refer the OSS Notes- 46919 and this thread,

SNP Heuristic: Creation of purchase requisition

Hi experts,
we face following problem: heuristic creates purchase orders when there is no source of supply.
Background:
there is a forecast demand for a location product on a customer location without transport lane to the production plant due to false master data.
The SNP heuristic generates purchase requisitions to fulfill the demand and there is no requirements shortage.
So it is hard to recognize which forecast demands can't be fulfilled.
Is there a parameter in material master or in a heuristic profie which disables the creation of purchase requisitions in snp heuristic when there is no source of supply.
If no purchase requisition is created there will be a requirement shortage which can be recognised by an alert.
Thanks for your help.
Robert

hi.
As per heuristic process , the system will create a purchase requisition if there are no Tlane exists and the material's procurement type is F/X since it is a infinite planning.
Now you can use a optimizer or CTM to restrict the system from creating purchase requisition.
Also you can try with location heuristic.
Hope this can help.

kaushik

SNP purchase requisitions inconsistency

Dear experts,
i have a question regarding purchase requisitions in the SNP planning. We have integrated purchase info records and purchase contracts from R/3 and we are using them as sources ouf supply in the SNP planning. The SNP heuristic applies purchase requisitions, but it don't delete them if the demand has disappeared.
The support told us, that the cause of this behaviour is the missing means of transport in the transportation lanes. Purchase requisitions which are generated without means of transport are inconsistent and the heuristic can't delete them.
I wondered about this statement because the lanes are generated automatically via CIF but without means of transport. Unfortunately we have to maintain them manually now for hundreds of lanes. With means of transport it works pretty fine.
Did anybody make the same experiences and what was your approach?
Kind regards,
Christian

Hi,
I thought these points might be of some help to all
1. SNP heuristic being a infinite planning create pur req even if no source is defined, with source and MOT blank, this behaviour is also observed when no MOT is defined for a lane or the MOT defined is not SNP relevant (i.e. relevant for aggrgtd planning).
2. You need to define both product specific lane and MOT lane to generate a proper Purchase req with source and MOT.
3. SNP heuristic cannot delete any transaction data that it cannot create or has not created.
I hope this helps, also you can use BAPI to define Transportation Lane (Product spec and MOT spec) which is a very convinient and useful way of creating Transportation Lane Master Data.
Thanks,

Purchase requisition for service activity / element cannot be generated

Dear SAP MM Experts,
This is a service Creation from the PM order to Purchase Sercive Requisition.
The Error Message Is Generated :Purchase requisition for service activity / element cannot be generated
Diagnosis
Due to the system settings, the system is trying to generate a purchase
requisition for a service activity or a service activity element.
No service package has been created for the activity/element.
As a result, the system cannot generate a purchase requisition.
The activity/element is created or released, but the indicator for
generating a purchase requisition is not set.
Create a service package for the activity/element and then generate a

No Purchase Requisition Generated after MRP Run MD02

Hi All,
After runing MRP Run MD02 for finish product with MRP Control parameters for create purchase requisition as 1 (Create Purchase Requisitions) . System is not generating any purchase requisitions for raw materials required for assembly.
If we select 3 create planned order system is able to generate planned orders for raw materials required for assembly.
Plz guide why am not able to generate purchase requisition directly.
Regards,
Sipra

Sipra,
Couple of checks,
1. Check whether the Material is defined for "F" - External Procurement in MRP2 view of the material master.
2. Check whether the material type used for the material is enabled for "External Purchase orders". Transaction OMS2.

Purchase Requisition Automatically Generating Issue

Hi Guru:
I failed to generate the purchase requistion after MRP running via transaction md03,please see my setting of MRP1-4 as below:
MRP1:PD as MRP type,then the reorder point is 300,the measurement of unit is KG,I set FX as lot size,and fixed lot size is 100.
MRP2:the procurement type is F,and plan delivery time is 2 days,GR processing time is 1 day.
MRP3:period indicator is M,availability check is 01,total replenish lead time is 3 days.
And I had maintained the contract and source list to this material,but it cannot be generated purchase requisition automatically,what's wrong???Help!

You can run MRP again with proper parameters and you will get PurReqs directly instead of PldOrds:

MRP no purchase requisition generated

Dear Experts,
I have a problem that I can't generate purchase requisition after MRP run.
Example : I have a finished goods material FG and under which has 1 component Mat 1.
The setting in material master of Mat FG is internal procure(E), MRP type = "PD".
Mat 1 is external procure(F) and MRP type = "ND"
I entered the forecast requirement in MD64 for Mat FG and I set the Create PR indicator to 1 in MD02
and start running MRP.
Planned order created for Mat FG, but no PR created for Mat 1 which only shows dependent requirement for Mat FG in MD04.
I can't see there is Mat 1 in the planning file(MD21) under Mat FG.
Any settings I missed and can anyone help?
Thanks a lot.
Claude

Hi,
IF you do not maintain mrp type PD then system wont consider the material during MRP run, so convert it to PD.
Also go through the below link which will clear your doubts of master data maintenance for MRP.
