MRP Purchase req renumbered

Hi experts,
MRP generates PR for our materials that stock level goes below rop...
We have a release strategy for the PR. So once a day we release those PR proposed by MRP. the majority are converted to a PO and eventually received. Which is fine.
But some PR that were released are not converted to PO right away. At the next MRP run these material/PR are updated and have a new PR number. So we must release again.
Is there a way to prevent this?
thanks Daniel

from OSS Note 365604 - FAQ: Release strategies in purchasing
If you have purchase requisitions from material requirements planning (MRP) (EBAN-ESTKZ = 'B') that are subject to a release strategy, the system may reset a PReq release when the MRP is restarted. In this case, you should set 'Fix for material requirements planning' for the relevant release indicator (V_161S-FIXBP).

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

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.

MRP- purchase req. without price

Hi gurus.
I have materials with stock transfer as special procurement (MARC-SOSBL) from other Plant.
When I run MRP, PR is created without price despite that material has price in supplying Plant.
However if I create PR manually with the same data, PR is created WITH price.
I really appreciate your comments.

Hello everyone!
Do you know why is not possible to create a Purchase Requisition without a Plant? I'm trying to do that too...
thank you in advance.

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.

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

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

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"..

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...

Regarding rescheduling of purchase req.

Hi All,
For raw materials I have maintained safety lead time in the material master and I conduct MRP run. System create the purchase requisitions after MRP run. When I check the requirements in MD04 for the raw material, system show me rescheduled date.
But it doesnot mean that system has rescheduled purchase req.
Is there any transaction, so that I can reschedule the purchase req. ?
Regards,
Mahesh

Hi,
Do you notice a star indicator next to the PR, if yes it means a firming of the PR has taken place. This firming can be due to manual modification or due to the PR falling in planning fence and an automatic firming.
MRP does not make changes to firmed proposals. So just close this PR & re-run MRP & system will generate an unfirmed PR. The MRP run will schedule the proposal on the need date.
Hope it clarifies.
Regards,
Vivek

Planning Time Fence and Rescheduling Purchase Req

How to Process the MD04 exception u201C30 Plan Process According to Scheduleu201D for Purchase Req.
Please provide me a Step by step procedure with example to Reschedule the Purchase Req with given rescheduling date.
*Really I am confused with PLANNING TIME FENCE.
What it does with Planned Order and Purchase Req ?
Based on the some of threads in SDN, I couldnu2019t come to the conclusion of the terminology behind PTF.
So could you please provide me an explanation with example will make clear idea on PTF.
Thanks in Advance.

dear friend,
as far as i know, all planned orders that lie in the planning time fence are firmed. that means that they can no longer be changed automatically by the system in the planning run in long-term planning.
outside the planning time fence, the system creates order proposals as usual according to the shortage quantity and the lot-sizing procedure. once these planned orders move into the planning time fence, they are automatically firmed depending on the how you have set the firming type.
the planning time fence can be defined per material in the material master record or via the MRP group.

Third-party Order - purchase req's to SRM

Hi
We are using EBP 4.0
We are creating sales orders with item cat "Third Party Item", the purchase req's are created in R/3 but we have problems when we transfer the purch req's to SRM via BBP_EXTREQ_TRANSFER.
There is an errormessage in SMQ1 "<i>Partner not Found</i>". I have also checked SLG1 in SRM but there is no additonal info there.
I think the problem is related to the Customer (ship to), it looks like the Businnes Partner has to be created for that customer but I don't really understand how it works.
Any tip ?
Thx
Anders
PS we can transfer normal purchase req's created by MRP to SRM without problem.

Hi Andres,
I think this scenario is not supported by SRM. These requisitions will have eban-estkz = 'V' and there is a check iin the plugin routines which exclude these requisitions from going to SRM. It will be a modification to make this go through SRM and will not be supported.
I hope this helps.
Thanks and Regards,
Vani
