MRP:regeneration of pr

MRP was run in my company and a pr was generated and this pr was converted to po but grn against this po has not been done.But on running the mrp again another pr was generated for the same material for the same quantity and this pr is shown in the mrp pr print out.we follow reorder point planning.i.e in a nut shell for the same requirement multiple prs' has been generated while running mrp.please advice

Hello,
For Requisitions generated by the MRP, if the fixed indicator on the Requisition is not selected or the release indicator does not have a final release, then when MRP is run again the original Requisitions can be deleted.
So what may have happened in your system is the following :
- The MRP created Requisitions that were consequently not fixed (i.e. EBAN-FIXKZ = blank), which is normal.
-> A Requisition becomes fixed in ME52(N) only if at least one of the
    following fields are changed EBAN-MENGE Quantity
                                 EBAN-LFDAT Delivery date
                                 EBAN-FRGDT Release date
                                 EBAN-LGORT Storage location
                                 EBAN-WEBAZ GR processing time
-> A requisition becomes also fixed with a final release strategy.
- A new MRP was carried on, with transaction MD01/MD41 for instance,
and the 'Planning mode' indicator was set to 3 'Delete and recreate
planning data'. This may have deleted the previous Requisitions.
The summary:
If you don't want to have such a behavior there are the following possibilities:
1. Avoid runing MRP during converting PR to PO
2. Runing MRP with another planning mode (not 3)
3. Indicate PR with a Release strategy

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.

Creating purchase requisitions instead of planned orders after MRP run in MDBT

When running regenerative planning in MDBT for plant with following details ,The system has to provides planned orders for the materials .
Processing key:NEUPL
Create Purchase requisition :3
Schedule lines:3
Create MRP list:1
Planning Mode:1
Scheduling :1
But sometimes it provides purchase requisitions for certain materials.The problem happens for different materials at different times.
I checked the material master and found that procurement type is external procurement.Business need to create planned order for the materials and then want to convert it to purchase requisition.
MRP group is assigned to the materials but no creation indicator maintained for the MRP group.
Please tell me why this run creates purchase requisitions suddenly and in the next run it disappears?

Hello
Maybe someonelse is running MRP in another transaction, such as MD02, with a different parameter. Check on transaction MD05 when was the last MRP execution and the user that ran it.
Also check if there is any active implementation of BAdI MD_MRP_PARAMETERS.
If you don't have a cretion indicator, maybe it would be useful to set it for your MRP group, with the parameter 3, in order to make sure that planned orders will be created.

Time stamp in MRP list after MRP Run

Hi Gurus
After running a MD01-MRP at scope of planning level, with processing key as NETCH, materials which had no planning file entry also were updated with the latest executed MRP run time stamp in MRP List MD05.
Is it the standard behaviour? As per my understanding, the materials with no planning file relevant change is not included in the MRP run with processing key NETCH/NETPL. Then how does the time stamp be relevant for the latest MRP run while the material was never included in the mrp itself?
Regards
Deepak Prasanna S

Dear Deepak,
If my understanding is correct only if a mterial is included in the last MRP run(MD01/MDBT) then the time stamp gets included in the
MRP list which can be checked and confirmed through MD05 and also the output of last MRP run.
Once after the MRP run is completed the system deletes the corresponding planning file entries in the system.
On completion of the planning run, the appropriate indicator is automatically deleted in the planning file:
The system deletes the net change planning indicator and the net change planning horizon indicator for a regenerative planning
run and a net change planning run.
The system only deletes the net change planning horizon indicator for a net change planning run in the planning horizon.
Check and revert back.

MPS & MRP

As i understand, MPS is single item, single level planning generally done for expensive items. we have md03 also in mrp for single item single level. then wht is the difference between two? thanks in advance.

Hello,
Yes what you have observed is right but there are also following additional features of MPS which can be used (these are not there with single item multilevel run - md03.
Planning Time Fence
You can protect the master plan from any automatic changes to master schedule items in the near future by using a planning time fence. Within the planning time fence, the system does not automatically schedule or change the procurement proposals. Therefore, the MRP controller has time to plan the master schedule items manually. However, to support the MRP controller, the system can create necessary procurement proposals and schedule them for the end of the planning time fence. You can then schedule these procurement proposals manually as you wish.
Processing the Planning Result Interactively
With interactive planning, you can check the results of the automatic planning run for master schedule items with simple and easy-to-use tools and simulate changes and regenerative planning. The system does not save the planning data in the database until you save the interactive planning.
Interactive planning is especially useful for adjusting dates of planned orders falling within the planning time fence.
Evaluating the MPS Run
With the help of the user-friendly structure of the planning results, you can react quickly and efficiently to any problems that may occur. A series of standard evaluations are available within MPS to achieve this. You can also generate individual evaluations according to your specific needs.
Hope this satisfies you. Award points if benefitted.

MD04 Transaction and MRP related queries

Hello All,
i have some specific questions regarding MD04 and MRP Run
1. In MD04 for few raw material i am getting -ve available quantities , i am not getting why MRP didn"t run for the same before available qty become negative , we have a batch job schedule for MRP run .
what all the possibilites of not running the MRP ,
We don't have reorder level planning ! MRP type`is standard one PD .
2. For some material we are not able to create a planned order, settings in Material Master MRP view is fine as we have another material with same settings are working , i am running the MRP through MD41 Transaction code >
Forecasting is done through MD61/62 active indicator ticked >
what else could be the reason .
Secondly one silly question does MRP take into consideration available stock during run , i mean if i run the MRP for a material with Tcode MD41 , will MRP create Planned orders , even if enough stock is available >
Thanks for coming back in advance .
Thanks and regards

Look for the MRP list as well (MD05), not only the Stock/Requirements List (MD04).
You can see there the date and time of the last MRP run, and if there was a termination that did not allow the proper run.
There may be a number of reasons why a material was not included in the MRP run, like what type of run (e.g. regenerative or net change), etc.

Invoice regenerated after canceling

Hi all,
we have a problem that occurs from time to time.
After we create for example a Debit Memo, we create a delivery and a billing document. Now sometimes we need to cancel the invoice again. So we go into vf02-billing document-cancel.
A new document number for the canceled invoice is created.
Now on the next day, the system automatically creates a new invoice for the one we have canceled.
But we don't want another invoice at that time.
So what could it be in the system that triggers the "automatic regeneration" of invoices the next day and how could we avoid that??
Thanks
Anne

Hi,
I have checked our batch jobs and there is no job that indicates right away that it would create invoices.
There is one job for a daily MRP run (RMMRP000).
Is it possible that the generation of invoices is somehow tied in into the MRP run?
Thanks
Anne

Regenerative planning run in APO

Hi experts,
I need your input on the following scenario.
We have APO PPDS implemented for our Manufacturing industry client. We have designed to run only Net Change Planning every day and there is no design to run Regenerative Planning.
What is the importance of running Regenerative Planning? What do we lose if we don't run a regenerative planning?
We have CTP scenario, so there are lot of parts planned automatically.
Is there any impact of automatic planning on Regenerative planning and vice versa?
What is the best practice to follow with respect to Regenerative Planning?
I appreciate if someone could answer these questions. Thanks in advance.
Regards,
Manimaran M.

Hello Mani
Following are details are from old SAP Handbook, good information to understand the concept.
====
Net Change Planning
Automatic material requirements planning is especially hard on system performance for production processes with complicated BOM structures. To guarantee frequent planning runs of those materials which are relevant for planning despite this problem, you can carry out the planning run with the "net change planning" procedure. This process only plans those materials which have undergone a change relevant to material requirements planning (for example, change in a production order due to excessive scrap, a new sales order, and so on) since the last planning run.
The so-called planning file exists especially for the planning run and contains all the materials and their respective MRP types. If a material is changed in a way that is relevant to the planning run, it is given a net change indicator meaning that it will be included in the next net change planning run. In a net change planning run, only these materials are planned.
Net Change Planning in the Planning Horizon
Performance can be improved even further by using the net change planning run in the planning horizon. Here, only those changes relevant to requirements planning that fall within a specific period (defined by the user and known as the planning horizon) are included in the planning run. It is advisable in this situation to carry out a total planning run in regular intervals (for example, weekly or monthly) to keep the planning results completely up-to-date.
Regenerative Planning
It is also possible to carry out a regenerative planning run. In this planning run, the system plans all materials that are relevant for planning. Usually, the regenerative planning run is only carried out in the implementation stages.

Hope this will help.

MRP REGEN Issue

Hi All
      Could you guys help me to solve out this issue will be grateful
          In my client there are two plants, let us consider plant A & plant B. In both the plant we are running the MRP REGN job weekly with the parameter set-up as following.
Plant:                Plant A.
Processing Key:     NEUPL.
Create Purchase Req:     2 [Purchase Requisition in Opening Period].
Delivery Schedules:     3 [Schedule lines].
Create MRP List:     1 [MRP List].
Planning Mode:     2 [Re-explode BOM and routing].
Scheduling:          2 [Lead time scheduling and capacity planning].
Plant:                Plant B.
Processing Key:     NEUPL.
Create Purchase Req:     2 [Purchase Requisition in Opening Period].
Delivery Schedules:     3 [Schedule lines in the opening period].
Create MRP List:     1 [MRP List].
Planning Mode:     2 [Re-explode BOM and routing].
Scheduling:          2 [Lead time scheduling and capacity planning]
As per the above set-up we are facing a problem in REGEN job for PLANT A as, When ever the REGEN job runs, it kills all the open purchase req and recreates the purchase req with same qty for non account assigned requirements [Purchase Req].
In PLANT B- REGEN job is working fine as we expected like that, It wonu2019t kills the open purchase req.
My issue is PLANT-A whenever the MRP REGEN jobs,it should not kill the open purchase requisitions.
What are all the steps I need to proceed to avoid the killing of open purchase req and regeneration of new one with the every run.
Thanks in Adavance.

Hi Rajesha Vittal,
                   We are running NETCH & NEUPL in our plant, so NETCH & NETPL are more are less same.
I am looking forward the solution to solve out the REGEN [NEUPL] issue.
Please help me..........
Thanks in Advance

MRP-jobs issue

Hi All,
I am in need of you guys help in understanding the MRP-REGN job [NEUPL]
Please help me.........
Here are the following statement I read in help.SAP
During regenerative planning, all materials are planned for a plant. This makes sense when you are carrying out the planning run for the first time as well as later during production if data consistency cannot be guaranteed due to *technical error.*
In the above statement they mentioned about Technical Error
What does it mean ?
when it will occur?
Can you guys could give me some examples of Technical Errors?
How can we get ride of the Technical Error without running MRP-REGEN [NEUPL].
Other statement I came across on help.SAP
If you have changed the settings of an MRP type, a lot-sizing procedure or a purchasing department processing time in Customizing, the materials that are affected by these changes thus have no planning file entry and are not included automatically in the net change planning. To enable the changes made to take effect, you choose regenerative planning in the initial screen of the planning run or make an entry manually in the planning file.
Material Master and all power users will frequently use to
change based on their need on MRP type and Lot -sizing , then If we change frequently then we have to run MRP-REGEN regularly?
or MRP-NETCH will take care .
my next question is
If we have a demand or any goods movement automatically planning file entry will be created for the material then why in the above statement they asked us to create a Planning file entry. If planning file entry will be created- MRP type changeor lot-sizing or purchase department processing time change will be taken care by MRP -NETCH job? or we need to run MRP-REGEN?
Thanks in Advance

Reg.No MRP List exist

Dear Experts
I am getting the following error
" No MRP List exist " when I run MRP in MD02. Pls help me
Thanks in advance
Rajakumar.K

Liting,
If this is the case, and you are sure you have set the 'MRP list' parameter as '1', then it implies that you are either excluding the material from the MRP run (scope of planning? Userexit?). or that you have had an error during the MRP run which caused the run to abort for that Material. Check the MRP logs for 'abnormal end'.
Also (probably not the problem, but can't hurt to try) try to repair any possible inconsistancies in the planning file using MDRE.
Less likely, but still possible, is that someone has deleted the lists (MD05 data) after they were run. This can be done by using MD08, and can also be done by a batch job. Look for batch jobs which use program RMMDKP01. If there were no changes to the material that would have triggered the 'NETCH' criteria, then MRP would not create a new list. To alleviate this scenario, some companies run Regenerative MRP periodically (once a week, or once a month, or once a quarter).

Pur req not generated for MRP element Planned order in stock reqmnts list

Hi SAP Gurus,
I have a problem where in MD04, pur req is not generated for the MRP element Planned order for a future date (about two months from now). Is there a specific reason? why is it not being generated? The MRP type is PD. The procurement type is F - external procurement. Can anybody please help me on this?
Thanks
Anusha

Anusha,
?? Not sure I understand the question. Are you saying MRP is creating planned orders instead of purchase reqs? Or, are you saying that no proposals at all are being created outside of two months? Or, are you saying that the system is creating purchase reqs inside of two months, and planned orders outside of two months?
Regardless, these problems are probably related to your MRP settings. Try the following settings:
NEUPL   Regenerative planning
1       Purchase requisitions
3       Schedule lines
1       MRP list
3       Delete and recreate planning data
2       Lead time scheduling and capacity planning
on your MDBT screen.

MRP - Transaction WC27 Batch Run for MRP

Each day we run WC27 as a background program. We have it configured to define the scope of planning (all of the plants that we want MRP to run). We also have a user exit key. The user exit parameters, is a set group of specific MRP controllers. Materials (part numbers) that have this specific MRP controller should run the MRP control parameters for Scheduling = 2.
The other parameters are as follows:
Processing Key = NETPL
Create Purchase Req = 1
Schedule lines =3
Create MRP list = 1
Planning Mode = 3
We currently see each day, materials (part numbers) that the routing was changed to a different work center using CEWB. However, when the background job runs for MRP (WC27), it does not update the planned orders with the new routing work center change for the material (part number) that has an MRP controller specific for the scheduling parameter set to 2. Why would our MRP run not change the planned order? If, I run MD02, it does update the planned orders. So why is not changing it in the batch run? It is causing issues with our end users running CM25 for a specific work center.

Hi,
a.     Please check if the material in question has the Planning file entry u2013 through MD21
b.     If the planning file entry is not seen, create Planning file entries using MD20 or MDAB
c.     Run MRP (MD01 or WC27) with Planning mode as 3 or 2, and check if your changes have got effected into the Planned orders.
When we use Net-change planning at the Plant level, the system checks for the presence of Planning file entriesu2026 and whichever material has undergone some changes relevant for MRP, and thus having the planning file entries are covered during the MRP run.
Workcenter or Routing changes do not result in creating Planning file entry.
At the same time, when we execute planning for the material level (MD02), the planning run does not refer to the Planning file entry and hence the planning run changes the Planned order master data.
Kindly refer to the definition below..
u2018In net change planning only those materials are planned for which the net change planning indicator in the planning file has been set as a planning file entry. The system usually sets the indicator automatically as soon as a change is made to the material that is relevant to MRP.
The following changes cause an entry in the planning file to be made:
u2022     Changes to stock, if these change the stock/requirements situation of the material
u2022     Creation of purchase requisitions, purchase orders, planned orders, sales requirements, forecast requirements, dependent requirements or reservations
u2022     Changing to fields that are relevant to the planning run for these receipts and issues or in the material master
u2022     Deleting receipt or issue quantities
u2022     If you have changed the settings of an MRP type, a lot-sizing procedure or a purchasing department processing time in Customizing, the materials that are affected by these changes thus have no planning file entry and are not included automatically in the net change planning. To enable the changes made to take effect, you choose regenerative planning in the initial screen of the planning run or make an entry manually in the planning file.

DIMP 471 to ERP Upgrade requires MRP regen

With our trial upgrade from Enterprise 470 with DIMP 471 industry to ERP 60 (basis 13, app 11, ECC - DIMP 11, we are finding it necessary to delete all mrp lists and run regenerative mrp for all plants to prevent an abap dump with collective mrp lists.
mdtc is the table involved. We have been unicode for a year now so it is the change to erp60 with DIMP that has required this rather tedious post upgrade process. There are no notes about this. Has anyone encountered this?

The dump is :
Runtime Errors         CONNE_IMPORT_WRONG_STRUCTURE
Exception              CX_SY_IMPORT_MISMATCH_ERROR
Short text
    Error when importing object "MDTBX".
55 *   Einlesen komp. Dispoliste
>>     IMPORT MDTBX FROM DATABASE MDTC(AR) ID DTNUM_OLD.
57   ELSE.
Solution is to follow advice in note 1009454 that was about a Unicode error with DIMP but is also relevant to this situation.
After the release upgrade, delete the old MRP lists using transaction MD08. Afterwards, you can create the MRP lists again using an MRP with the NEUPL processing key.

MRP-NEUPL

Hi All,
Could you guys please explain me briefly about the difference between NEUPL, NETCH & NETPL will provide me an understanding of MRP jobs.
Hi PP-Gurs,
please explain me the MRP-REGEN [NEUPL] basic characteristics and if I run with planning mode 1 or 2 what will be the result?
MRP-NETCH basic characteristics and if I run with planning mode 1 or 2 what will be the result.
Thanks in Advance

Dear Madhan
NETCH, NEUPL and NETPL are processing Keys for MRP Run entered in Initial screen.
NETCH u2013 Net change planning (If there is any MRP relevant changes made to the material its considered for the MRP run)
NETPL u2013 Net change in Planning Horizon (If there is any MRP relevant changes made to the material within the planning horizon itu2019s considered for the MRP run)
NEUPL u2013 Regenerative Planning (In a regenerative planning run, the system plans all materials which are included in the planning file irrespective of all indicators)
