Purchase Reqs in MRP

I'm looking for a possible explanation for the following replenishment issue:
After Retrieving the ZREQS report, the MRP system sometimes may recommend (multiple) plan orders for the same article, same order date and delivery date.
Purch.Req. Article Article Description Mdse Cat. Fix. Vend. Qty Requested Un Req.Date Release Dt Deliv. Date
10001260 200004013002 THONG BLACK M/1 114625009 115609 16 EA 10/24/2007 10/24/2007 11/29/2007
10001261 200004013002 THONG BLACK M/1 114625009 115609 493 EA 10/24/2007 10/24/2007 11/29/2007
Thank you for your help

Reports starting with a Z are not SAP standard, they are created in-house.
If you would use standard transaction such as MD04 to review this kind of situation, then you could get the pegged requirement for each requisition.
Means your PRs are created for different requirements. that you get individual requirements instead of collective is based on settings in material master and customizing .

Repeated purchase req. in MRP run procudure

Dear SAP experts,
Here at my client site, i have one scenario of mrp run of consumables.They maintain safety stock in material master MRP view,
I am using MRP type PD.Now after MRP run,system creates purchase requisition as per safety stock qty,( consider initial stock
is zero) now when i convert Purchase requisition into purchase order. i refresh the MD04 list, as soon as i refresh i get the
purchase req. converted into PO item.Upto this point its ok. but during this refresh function i get repeated purchase requisition
of the same quantity as previous one..Why this is happening? any specific reason behind this? my logic is not getting clear.
please assist me to find exact reason..
Thanx in advance..
Regards,
Ravi

HI
If the initial stock is zero then system will generate the PR for the safety stock also and then for the Dependent requirement.
Check and revert

Require Planned order + Purchase Req. through MRP

Hello Sirs,
I have a requirement for following scenario......
I have a FERT which has 2 Components, 1 HALB + 1 ROH (Purchasing Item)
When i run MRP (MD02) for FERT, i want Planned Order for HALB + Purchase Requisition for ROH.
As at present when i run MD02 it gives me Planned Order for FERT, but nothing for the ROH.
Is it possible to get Pl. Or + PR !? If yes, please guide me with the required settings.
Thanks in advance,
Harris Panchal

Hi Harris,
Yes it is possible.
Now if you are running MRP through MD02 then most imp Prerequisite is all the materials which includes both Header material and Component should contain MRP type PD,P1,P2 and not M0,M1,M2.
Also check below parameters also.
- In MRP 4 view of Header Material (FERT and Halb both) MRP for Dependent Requirements should be maintain as Materials for dependent requirements are planned (Blank)
- Check BOM valid From to TO date and also From to To Lot size of Fert code.
- If you are using Production version then check above parameters (checks no. 2) for production version also.

Purchase req type after MRP Run

Ca we control the type of Purchase req after MRP Run.
Now for every material it is creating "NB" type purchase req.
Can we control it material type or by mat number.
We have 2-3 purchase req types in system for Material.
Amit Shah

Dear ,
Goto -OPPR-Enter Plant Code and Maintain MRP Group -0000( as SAP Standrad for External Procurement ) -Select Scheduling /Doc Type tab -Here you can assing the PR type as per your requirement so the while MRP run , it will selct the PR documents types based on OPPR .At the same time , assing this MRP group in MRP1 view of the material .
Try and come back

Unfirmed purchase reqs not getting cancelled in the background MRP run

Good morning,
The system has created Purchase requisitions for 2010 due to the setting in the MRP run. we want to change it to planned orders outside the Vendor lead time and when i run a REGEN MRP with setting 2 (Purchase requisitions in opening period) its not happening. When i run indivudual MRP with MD03 with the same setting its alright, purchase requisitions are deleted and its converted into Planned orders. Can anyone please throw some light on to make backgrouond MRP run delete the Purchase requisition and create planned orders.

Jags,
You must delete the offensive PRs first. Regardless of the MRP settings, MRP will still decide that the PRs are valid and will leave them alone. It will not 'change' them into planned orders.
Run Regenerative MRP with your new settings (Create purchase reqs as '2') but also run your MRP in planning mode '3', delete and recreate planning data. It will delete all existing unfixed purchase requisitions, and then run MRP.

MRP run and creation of one cumulative purchase req

Hello,
mrp run is creating a lot of single purchase reqs with one line (quantity and dates are fine)
but how to set up MRP so that instead of multiple purchase reqs ONE purchase req with many lines is created.
Thanks, Sebastian

this is not forseen in the design.
Where would be the benefit? have a look into table EBAN.
There would not be one record less with this concept.
Further, in bigger organizations, several buyers would then work with the same purchase requisition, which could lead to lock and update problems.

Planned order created after mrp run instead of purchase req

Hi All,
I am facing a strange problem about planned order being created after mrp run jobs runs in background instead of purchase req. This is happening randomly. In the material master MRP view 2 procurement type is F and in the varient for the MRP job the in Purchase requisition control parmater 1 is marked that is purchase requisition. Also planning file is having the entry once there is shortage and hence MRP run is there always if there is shortage of material.

Hi Tarun,
Please maintain the control parameters as
Processing Key                                       NETCH

MRP Generating Purchase Reqs for Materials Needed in 2013

Hi, all. We're running MRP and it's generating a massive amount of purchase requisitions (18,310 to be exact).
The following is a typical part setup:
Lot size = EX
Planned delivery time = 5 days
GR processing time = 2 days
Individual/collective requirements = 1
MRP profile = BTO
We have one existing sales order with a delivery date in 2014.
With a lead time of roughly a week, why is MRP generating purchase requisitions out into 2013 for this material??
Thanks!
Sarah

Sarah,
MRP Profile doesn't mean much to us, they are all created individually during each implementation, and they are all different. However, I will guess that BTO is some type of Make-to-order profile.
You mention 18K of PRs. Are these all being created in a single run, or is it possible that they may have been accumulating for a while? To find out, run MRP, but using the parameter for Planning mode 'Delete and Recreate planning data'. It will delete all the unfirmed PRs and then regenerate new ones based on the current situation. I will assume for the moment that all these 'future' PRs are unfirmed, please let me know if they are not.
Since it appears to be a MTO environment (if not, let me know) then you should be able to see in the planning segment which requirement (sales order) is driving the purchase reqs. Depending on your MRP type, this could give you understanding of why MRP is proposing so many PRs.
One thing that will generate a large number of purch reqs is an unrealistic value in Maximum Lot size (MRP1 page of material master). For instance, for a requirement of 1000 widgets, and a max lot size of , say, 2, it would generate 500 PRs for 2 widgets each.
If my suggestions don't help you, please specify MRP Type, Lot Size, max lot size, rounding value, Safety stock, reorder point, Strategy group, From these values we can begin to understand your problem a little better.

Purchase Req. Document type during MRP Run

Dear All,
My reqmt. is that whenever I take MRP run of external procured items, System should generate Purchase
Req. for a particular Document type let say ZPE.as I want to control the no. range.
One thing I fopund was control through OPPR(MRP Group Settings).I have assigned the relevant MRP gp. to materials also,but still after MRP run,system picks up std.(NB) Doc. type for Purchase Req.
Kindly advise whether Iam missing some settings.

if you want sytem to create our own type, u can create assigning MRP Group for your material.
Goto OPPR , Assign your PR Docuemnt type in under "stnd pur order" coloum in External Procurement option in OPPR for your plant/MRP group Combination.
i hope u already have created ZPE Pur requsition doc type

How to avoid purchase req and stock transport order to take part in MRP.

Please suggest how to avoid purchase req and stock transport order to take part in MRP.

hi,
check the settings for the MRP type...there you need to show which doc will be taken into considerations...
SPRO >> MM >> CBP...
Under CBP check for the MRP settings where it is placed(check under master data settings)...and check for the indicator for PR's and STO's release orders under tab "Additional external req. in the reorder point planning"..

SAP Add Pricing Tier Logic to the MRP Purchase Req Calculation

Hi experts,
ISSUE: SAP Add Pricing Tier Logic to the MRP Purchase Req Calculation .
> MRP currently generates purchase requisitions based strictly on a calculation of inventory, open orders, forecast, and purchase orders. The purchase req quantities do not take advantage of the pricing tiers and their associated quantity discounts. MRP may recommend a PO for 913 units. At no time would a planner ever order such a specific quantity. In addition, the planner would increase the order to 1020 to get the price discount for 1000 units (rounded to 1020 for carton quantity). SAP should include a preset order table which would evaluate the MRP calculation and recommend an appropriate quantity based on the contract pricing tiers.
pls let me know it is posible or need any enhancement and how ?
thanks
humera

Hi,
Rounding profile works for u r query, there u can maintain quantity rounding for purchase process, also the rounding off method will set the limit of rounding for given unit of measure. The rounding off method can be maintained in SPRO > Material Managment>purchasing >order optimizing> Quantity optimizing and allowed logistic unit of measure-->Unit of measure rounding rules.
Hope this will help u.

Stock Transfer Reservation in spite of Purchase Requisition in MRP run

Dear SAP gurus,
We are running MRP heuristic on the PP/DS and we have different results comparing our development and productive environments.
In our productive environment purchase requisitions are generated and in our development environment stock transfer reservations are generated as result of the MRP run.
Where can I check differences of configuration that would be causing this?
Thanks and BR
Mauricio

Mauricio,
I guess I was not clear in my suggestion, I apologize. Differences in T001W between ERP dev and prod will not necessarily generate your problem, differences in sourcing within APO between APO dev and APO prod will generate the differences. I only mentioned the vendor number because a transportation lane can exist 'source plant > destination plant', but also you can have a transportation lane 'vendor of source plant > destination plant' which would also have an impact on the type of req created.
Easier to check the sourcing, //PWBSRC1, mentioned earlier. Your dev system should contain no objects that relate to Stock Transport orders. You can delete the STO sourcing records within that transaction, which will also delete the material assignment to the Transportation lane. Hopefully you will then get the default external supply proposal, which is normally a Purchase req.
Also check for presence of quota arrangements //SCC_TQ1. Delete any that unnecessarily refer to an STO object.
Best Regards,
DB49

Inconsistent Dep req in MRP run

Let me explain the scenario with an example:
B is child part of A. When we ran MPS, A's planned order has generated dep req on B. Subsequently A's Requirement and Planned order were deleted . But in the subsequent MPS run it is not deleting Child parts (B) dep req due to some error. ( We know the mistake what we did). Now we wish to delete this inconsistent Dep req for B.
I know that there is a program RM06C020 to delete such sub contracting purchase req . Similarly is there any program for deleting inconsistent dep req for a planned order?

Hi Srinivasan,
To delete the inconsistent dependent requirements of planned orders...you have the only option to run the MRP for the header part so the dependent requirements will be deleted and adjusted automatically as per the new planned orders quantity.
There is no program and transaction to delete the dependent requirements except MRP.
If any questions then write to us OR close this thread with rewarding the suitable points.

Info Record and Purchase Req

I created a purchase Req and when and I have following doubts in this.
1. Once I entered plant itu2019s automatically populating storage location. Material maintained for different storage locations but I am not sure how it's populating specific one.
2. One I click on source of supply it shows me different info record and I selected one of the info record for assigning the source. How this process is different from mE57.To me both look same.
3. I created the PO and I entered different price then info record and my info update was checked but still it didn't update info record with new price. Any suggestion why?
Thanks

hi,
1. You would be maintaining the MRP view of the MMR....Never forget the possible assignment for the Plant to the storage location is provided in the SPRO enterprise structure for the MM....
2. Yes the process is merely same...Also never forget that there may be many inforecords for the vendor material, based on the different organisatinal levels provided and for its combinations...
3. THe price never gets updated in the info record, but always the PO price history gets updated...you can see the PO price history in transaction ME1P...
