MRP run performance

Hi,
We have upagrded from 4.6c to ECC 6.
During testing, we find that the MRP Run takes very long time, which is very abnormal.
Can anybody come up with some reason for this behaviour?
Here are some inputs.
Planning run through program - RMMPS000
Parameters:
NETCH
Purchase Req - 2
Scheduling lines - 3
Create MRP List - 1
Planning Mode - 1
Scheduling - 1
MRP Process for all the materials - activated
Parallel processing - activated

Excluding storage location from MRP run in Long Term Planning

Hi,friends,
In my scenario , i want to exclude storage location from MRP run in long term planning.When i set storage location MRP indicator "2" in SPRO and SLoc MRP indicator "1" MRP4 in material master, i can exclude the storage location after run MRP with MD01/MD02,and i can see the expected result in MD04.But in Long Term Planning scenario the storage location can not be excluded after run MRP with MS01/MS02,and the requirements list in MS04 include the stock in the storage location i want to exclude. i dont know if i miss something.Plz give me some advice.
Regards
Joey

Hi,
Refer the OSS Note 208017 - LTP: Long-term planning and storage locations
==========================================================================
Symptom
In long-term planning (Transactions MSBT / MS01 / MS02 / MS03), the MRP indicator of a storage location for a material is not taken into account (material master, view MRP 2 [up to and including Release 3.1I] or MRP 4 [as of Release 4.0A]).
The storage locations excluded by MRP or planned separately are also planned in the plant segment.
Additional key words
LTP, MM01, MM02, MM03, master data, MRP indicator, LGORT ...
Cause and prerequisites
The MRP indicator for a certain storage location of a material is only taken into account in operative planning (requirements planning, MRP).
The long-term planning occurs exclusively at plant level.
Solution
This is no error. The system works as intended.
The individual storage locations should not be distinguished in the long-term planning, in order to perform a comprehensive long-term planning.
This is important, for example, within the kanban processing where the storage locations with kanban MRP are excluded from the MRP, but in spite of that should be included in the long-term planning.

How MRP Run exclude QI Stock Type of a Raw Material SLOC?

Dear all
Fact:
All of our raw materials must be subject to quarantinee upon GR. We have Storage Location of Raw Material: RMSL
In Material Master of that Raw Material
We are using the "SLOC of EP" (MRP View 2) to put the defaulted GR SLOC. And we also make use of the "Post to QI Stock" in View: Purchasing.
Upon GR:
During GR, the Raw Mat SLOC (RMSL) will be copied from "SLOC of EP" of the material master data, and it will be posted to the stock type "QI STOCK".
Problem:
However, when the MRP Controller run MRP, it will take the QI Stock Type of Raw Material SLOC into account.
Is there anyway we can exclude the QI Stock Type of Raw Material SLOC from MRP Run?
I have read from some threads to suggest to post it to the Quarantinee SLOC. We prefer not to create another Quarantinee SLOC (QISL) which will be filled in SLOC of EP and then after passing QC, we perform Transfer Posting from SLOC: QISL to SLOC: RMSL. We have a few Raw Material SLOCS and we do not want the Warehouse guy to get confused which Raw MAterial SLOC to choose upon GR. Rather, we prefer it to be defaulted in the "SLOC of EP" in the material master.
Please advise.

Hi,
Generally MRP consider stock from all the storage location when run the MRP for Plant level for material.
However we can exclude the particular storage location from MRP Run, for those following settings to be done.
Go to MRP-2 View of material master and select the storage location to be excluded from MRP. (Press Shift +f1 ex .sloc2) As per your case it should be RMSL
In that MRP view go to Storage location MRP Tab.
And assign u201CSLoc MRP indicator = 1 (Storage location stock excluded from MRP)u201Dand save.
Now run the MRP, stock from sloc2 will not be considered to create-planned order.
Please try this and revert back.
Cheers,

PR after MRP run

Hi,
After MRP run we want the valuation type system should pick up automatic in generated Purchase requisition. Can you please confirm how it is possible ?

Hi Sun Riser,
If purchase requisitions for materials subject to split valuation are generated within materials planning (Transactions MD01, MD02, MD03), the system does not supply a default value for the valuation type. The header record is generally used (without valuation type). This is standard behaviour please look at note 15297 Materials planning: No valuation type defaulted. Workaround is when you enter the valuation type during conversion PReq -> purchase order, an account determination is performed with the corresponding valuation type automatically

MRP run - misalignment for planned order between Date and Production Date

Hi All,
We've just integrated SAP for a new plant.
The MRP runs based on Routing Lead Time for Make materials instead on Material Master Lead Time, for Capacity Assessment purpose.
When requirements dates lay in the past, MRP performs forward scheduling starting from current date and properly defines Production End Date according to Routing.
By checking MD04, for the proposed Planned Order, the basic date is same as Current Date (= same as Requirement Date) instead of being same as Production Date.
It works as it if checks stil the MAterial MAster LEad time instead of Routing. In fact if I updated the LT of MM the MD04 provides the right Date.
For future requirements, the MRP works properly, by having basic dates (both start and end date) aligned with Production Dates of Planned Order.
How can I do the alignment w/o updating In House Production LT?
Thanks,
D

Hi Caetano,
we have already done this configuration in OPU5 but it doesn't provide any benefit.
Below how we configured it:
Scheduling level: Via detailed scheduling
Adjust dates: adjust basic dates, adjust dep. reqmts to operation date
For capacity scheduling: Always basic dates, dep. reqmts to operation dates
Scheduling type: Backwards.
Regards,
D.

In MRP Run for FERT, i want to eliminate 3rd level HALB and their BOM compo

Hi All,
Can you please guide me on this issue please.
Regarding - In MRP Run for FERT, i want to eliminate 3rd level HALB and their BOM components for exploration and planning
My scenario is:
Level 1: FERT1
Level 2: HALB1.1 + ROH1.1 + VERP1.1
Level 3: HALB1.1.1 + ROH1.1.1
Level 4: ROH 1.1.1.1 + ROH1.1.1.2
While performing MRP run i dont want to include the material HALB1.1.1 (Level 3 component) and their corresponding BOM component (ROH 1.1.1.1 + ROH1.1.1.2)
My constraint:
The reason for this is HALB1.1.1 is being manufactured through REM profile with separate PIR and MRP run.
But it is being consumed in FERT1 through intermediate semi-finished HALB1.1. and it needs to include for Product costing.
Note: All materials have been marked as PD - MRP type
Would be a great help from you.
Thanks and Regards

Reg.MRP Run without sale order

Dear Experts
We are in need of MRP run without sale order. I have created Finished product material (T-Shirt) and assigned components to that and then I ran MRP, If I do so, MRP is exploded but result is not satisfied some non components are displayed.
What is my requirement is ,when I run MRP if there is stock availble production order should be created otherwise Material requirement has to created.
Pls help what is the configuration for MRP run,
Thanks
Rajakumar.K

Hi Raja,
One of your requirements isn't available in R/3.
What is my requirement is ,when I run MRP if there is stock availble production order should be created otherwise Material requirement has to created.
Standard MRP will create Dependent requirements (demand elements). MRP will create order PROPOSALs (purchase reqs or planned orders)(supply elements). MRP can be immediately followed by an additional program that will convert planned orders to Production orders. All these things are possible.
However, MRP will not check for the availability of components, and then selectively create production orders. Availability check, which is not part of MRP, is usually performed at a later part of the production order cycle.

Need clarification for MRP Run

Dear SAP Guru,
Need the clarification for MRP Run:
1.At the time of MRP Run what is the status function for - shipping notification?
2.First i have run the mrp planning mode is normal after that i have some changes in material master , so planning mode is - RE Explode planning & Bom ? AT THE TIME OF MRP RUN it is correct
3.In background MRP Run at MDBT - what is the PLANNING MODE ?
4. How will work on automatic PO Create through MRP Run PR\S.?
Kindly give me the feedback , i am waiting for your reply.
Thanks,
Uma

Hello Uma
1 - A shipping notification is a confirmation from the vendor that the material has been shipped.
2 - When you change your BOM or material master MRP settings, system automatically set a flag on the planning file to re-explode the BOM. Therefore, MRP automatically re-explode the BOM, even with planning mode 1. Planning mode 2 is only necessary when you need to force a new BOM explosion and I don't recommend you to use it frequently, as it may lead to performance issues. See my document MRP: Why shouldn’t I use planning mode 3 on a productive system? for more details.
3 - See notes 206666 MRP: Control parameters during planning and 135788 - Planning mode in material requirements planning.
4 - MRP does not create or change purchase orders or production orders. MRP can only create planned orders, purchase requisitions or schedule lines.
At last, I wrote the following document with links to the MRP FAQ notes, which may be helpful to you:

MRP Run for Multiple plants

Hi Guys:
IN SAP R/3
My client has requirement to merge planning of material for multiple plants and run the MRP under one head plant.
For example:
Plant : 1000, 1001, 1002, where plant 1000 is a head plant who had authorization to perform MRP run.
if I run MRP Sepeartely:Each plant has below requirement for one material number (M1)
Plant 1000 : 3 EA
Plant 1001 : 2 EA
Plant 1002 : 5 EA
Instead of running MRP per plant, my client needs to run MRP for multiple Plants that Consolidate total requirement for all plants.
and generate PR--->PO , In the PO, M1 should be delivered to 3 different plant locations by vendor and Po Will be issued from Head Plant 1000?
Is there any Report in SAP , Where MRP Controller can See Requirements from Different Plants @ Central Purchasing level after one Multi Plant MRP run, So that he can decide on how much to allocate to each plant?
Thanks for help
Thanks
Sweth

Hi,
If u want to perform the MRP in one plant for all the plant requirement is depends on the bussiness process.
You can try the following scenario:
Planning in one plant nd production in other plant - Respective master data and special procurement have to maintain.For
further clarity please follow the below link
http://help.sap.com/saphelp_46c/helpdata/en/f4/7d3f9344af11d182b40000e829fbfe/frameset.htm.
We can evaluate the PR and PO by providing the authorisation object for the multiple plant to the respective users.
Revert me back in case of clarification.
Thanks

Converting material PO text from Plnd order to Preq after MRP run

Hello;
I would like to know how is it possible to convert material long text to the Preq after the planned order is converted into Preq after MRP run.
I've checked in the text linkages in SPRO but didn't the option for copy rule for plnd orders to Preq.
Can someone tell me if it's possible, if so how.
Ibou

Hi
There is no settings in standard for this, but this can be achieved by development. SAP does not provides this functionality in standard SAP because of performance issue. Please refer to SAP note 27136 on this.
To get the text copied, you can ask ABAP programmer to implement Badi MD_CHANGE_MRP_DATA and put a logic to read text from material and copy in PR.
Hope this will help.
Thank you

Order of delivery schedule line counter at schedule agreements from MRP run

Currently we are using schedule agreements for our long term external suppliers, but we are facing a problem with the order of new delivery schedule lines created during MRP run.
Because of master data settings like, lot size, rounding value, plan delivery time and planning time fence to set as firm new requirements, multiple schedule lines are created with no order for schedule line counter.
Does anyone is aware of a BADI, user exit or customizing control to have this schedule line counter in order?

Effect of manually created proposal on MRP Run

if there is any proposal which might have been created by the user manually & not via MRP run, does it have effect on the results of MRP.
will the system ignores the requirement as it has been covered already via manually created proposal.

Dear Geetika,
if there is any proposal which might have been created by the user manually & not via MRP run,
does it have effect on the results of MRP.
Yes definitely it have effect on MRP
MRP checks All Firmed Receipts & creates procurement proposals
will the system ignores the requirement as it has been covered already via manually created proposal.
Say for example demand is there for material as 50 PCS
Now manually user created Production order for that 50 pcs
Now if run MRP than system will not create any plan order as already Production order consists for 50 pcs
Again we have add demand for the same as for another 50 pcs
so now total demand became for that material is 100pcs
Now Run MRP system will create plan order for 50 pcs
As we have already 50 pcs of production order which is created manually
Hope the above clarifies

Purchase order status in MRP run

Hi Gurus,
I have a doubt in MRP run.
While doing the MRP run, can there be any open PO s or is it mandatory to close them.
Can you also please suggest me on how to run the MRP.

Hi,
MRP Run
Purpose
The Material Requirements Planning (MRP) function enables you to plan material requirements for complex manufacturing processes. You use the MRP Wizard to create and run MRP scenarios. The MRP Wizard generates recommendations for the production and purchasing orders required to produce the final product on time and in the required quantity. You then use these recommendations to create production and purchase orders in the Order Recommendation Report.
The order recommendation cannot be issued for requirements that happened in the past (before the present day). Since the purchasing or production process cannot be completed in time, the MRP does not mix the real past data with new recommendations for the same period.
Prerequisites
●     You have defined the
○     Planning system
○     Procurement method
○     Order mutliple
○     Minimum order
○     Lead time
See also: Item Master Data, Planning Data Tab.
●     You have set the time interval between orders. See also: Define Inventory Cycles.
●     You have defined the appropriate items as non-production bills of materials (if required). See also: Item Master Data, General Tab.
●     You have defined default warehouses. See also: Define Warehouses.
●     You have defined forecasts. See also: Forecasts.
●     You have selected the Consume Forecast option to make the system exclude existing sales orders from the forecast. If this is not selected, the forecast considers existing sales orders as an additional requirement. See also: Sales Order.
●     You have set the planning definitions. If you chose Consume Forecast, you have defined the consumption method, days forward and days backward. See also: General Settings, Inventory Tab.
Process Flow
       1.      Start the MRP Wizard.
       2.      Create a new MRP scenario or select an existing one. (See also: MRP Wizard: Select New or Existing Scenario.)
       3.      Define the parameters for your scenario, such as the planning horizon and item details.
You also choose your display preferences. (See also: MRP Wizard: Scenario Details.)
       4.      Define the data sources for requirements that you want to include in your MRP scenario.
For example, you define whether you want to consider the existing stock or the minimum stock level. You can also include a predefined forecast. (See also: MRP Wizard: Data Source.)
       5.      Save the scenario or run it.
After you run the scenario, the system displays the MRP Results.
If there are red figures in the result table, solve the problem and re-run the MRP.
       6.      Analyze the MRP results. You can display the final stock quantity before the MRP run or after it.
       7.      Save the recommendations and exit the MRP Wizard.
Result
After completing the MRP Wizard, you still need to create the purchase and production orders in accordance with the MRP recommendations. See also: Order Recommendation Report.
Hope this will help.

Raja

Is there a report to track the exception messages after a MRP run ?

We have a scenario at our client site where MRP run is not optimized to the fullest.
The planners are not trained on how to interpret those exception messages.
They are not trained on how to reschedule / expedite planned orders resulting from an MRP run.
Is there a report out in SAP that keeps track of
1) History of number of exception messages by type ( Expedite/Reschedule/Cancel)
2) History of number of exception messages that were acted on or ignored by the planner.
This is to create metrics on the usage of MRP exception reports by planners.
Appreciate your inputs..

Hi
The exception messages are dynamic and time dependant. You cannot have history of exception message.. If your user is feeling difficult to use standard MRP reports. Create a new report using a function module MD_STOCK_REQUIREMENTS_LIST_API
It gives all MRP data including exception messages.

Antony
