Please help me how to consider.I am running first time MRP , what are the things are to be taken into account while running MRP also.
Thx
Bhupendra Singh

Dear Singh,
I would suggest you to first check your master data,
1. MRP type,Lot Size,MRP controller,Time in days related to purchase and inhouse production,procurement type,Scheduling
margin key value.
2.MRP related settings in OPPQ for the plant.

Regarding MD01 MRP Run

Dear SAP Gurus,
The issue is PR is getting created for engineering during the MRP run of either Production / Materials. MRP controller for Production is 001 & material is 003 where as MRP controller for Engg. is 004, and we are not running any MRP for engineering items. Somehow PR is getting created for engineering items in the system.
Thanks,
Ramesh

HI
did you mention any MRP controllers in th exit key .
if you haven't mentioned any thing then system willplan for all materials.
if you doesn't want to plan for engineering materials
, then you remove the procurment typa or remove the MRPtype

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

Re: MRP Run

Dear All,
I have queries regarding the MRP Run Subject.
1. How is the periodicity fir MRP run is decided.
Is the Change in the plan ( Forecast ) changes is the criteria Or we look for some other criterias as well.

Hi,
The MRP is executed to plan the procurement, production etc.
Now for deciding the frequency will depend upon:
1. How much stock of Raw Materials you want to keep when you place the purchase orders.
2. How much stock should be there when you start production.
Ideally these should be zero, but in practical scenarios you keep some buffers for fluctuations.
3. For how long you want to plan with the MRP. Suppose you are running MRP to plan the next 3 months, then MRP should run before these 3 months get over or your stock falls below required level.
4. Lead times & Delivery times are taken into consideration, as stated above.
5. Consumption pattern for RM and other materials is also considered. If it is more, you would need MRP early. You can otherwise increase the order quantity but that will increase the inventory levels. So its a trade-off.
5. From SAP point of view, if it takes too much of system resources for longer times, then it should be used less frequently.
Moreover, the frequency should be decided by keeping the business in mind. When do the business requires the planning.
Hope that clears some points.
Regards,
Rohit.

Regarding MRP Run

Hi All Gurus,
Can anyone of you tell me what is the outputs of followings?
1) Suppose we put MRP Type PD ,Lot-size- EX,Min.Lot size -5, Availability check 01,then what is the o/p after MRP run?
2) we put MRP Type -ND,lot size -EX,Remaining same as above .
3) we put MRP Type -PD, Lot size-FX,Fixed Lot-100,Remaining things are same as above .

Hi Narayan,
Please find the answer as below
1.The MRP will generate Procurement proposals for the order quantity.i.e the effect of EX-lot for lot order . If the order quantity is less than 5, then also the procurement proposal will be for 5nos.i.e effect of minimum lot size.
2.Since MRP type ND no planning i.e. no requirements generated.
3.The MRP will generate procurement proposals for quantity 100. If more nos required, then many procurement proposals each for quantity 100.
Hope is is clear.
Thanks and regards

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

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.

When MRP run through background process in MDBT open PR and PO not comming?

Hi,
When MRP run through backgroung process in MDBT open PR and PO not coming in MDBT result.
Pls advise accordingaly.
Regards
rk

Ram,
Either I am totally misunderstanding your statements, or your business people are misinformed.
The output of MD01 (MRP total run in foreground) and the output of MDBT (MRP total Run in Background) ARE IDENTICAL, provided you have selected the same parameters.
Neither output contains a discrete listing of open Purchase orders and Purchase requisitions.
Standard output of both MD01 and MDBT are:
1. List of materials processed, with exception messages
2. Statistics
In addition, both of these programs also write MRP records to the MRP databases, provided that the "Display Material List" parameter is set. In this case, both of these programs will produce data that can be further reviewed and managed in MD05 and MD06. MD06 is the tool that most planners use to process the MRP database info.
If you wish to see a listing of the entire MRP results (either MD01 or MDBT), then execute transaction MDLD. This will produce either a spoolfile or a printed document.
For the PO or PR listings, review my earlier suggestions.

Production orders not to be considered during MRP run

Dear SAPeers,
i want to know how to ensure that open production orders are not considered during the MRP run.
the following is the scenario.
PIR for march after MRP run creates a planned order. this planned order is converted to production order. now this production order is processed but not completely confirmed and TECOed after a certain quantity has been produced.
now we delete the old PIR and create a new PIR in the next month. now we revoke the TECO status of the production order and run MRP. I want to know how to avoid MRP from considering the open production order and create planned order for the complete PIR quantity.
Thanks and Regards
Srinivasan

Srini,
what i am worried is shortfall of raw materials in case they were to open the production order in the current month after the planning has been done. how do we allocate raw materials for both the plan as well as the open production order?
Okay, you presumably had RM available for all of your production orders (and those RM were balanced by the reservations from the production orders). Now, you TECO the production order. In effect, any un-issued RM are now released and freely available for other orders/planned orders. Now you plan the following month. Those RM that were freed can and will be used for the new plan. Odd business process, but OK. Now, you re-open the production orders, and, yes, you will have a shortage unless you run RM MRP again. This is, ah, inconsistent with any business process I have ever seen.
The question that jumps to mind is, "Why re-open the old production orders at all? Alternatively, why were they TECOd in the first place?" If one knows that he intends to complete an order in production, one does not normally TECO the order, and then later reverse the TECO.
With respect to my name, I must unfortunately keep a low profile. Ever since I escaped from the mental institution, the thought-police have been hunting for me. I do not wish to be the recipient of any further electroshock 'treatments'.

Discontinuation Material in MRP run

Hi,
In our scenario, we are using Discontinued parts with (Discontinuation Ind - 1, Effectivity-out date - Nil) with follow-up material in MRP4 view of MM.
It is observed that whenever there is no sufficient stock exist, dependant requirement is not transferred to the follow-up material during MRP run. However is the same is happening during Material Availability check.
Is there any IMG setting for this to happen during MRP run also.
Thanks in advance.
Parthasarathy P

Hi ,Parthasarathy,
if an item to be disticontinued item , the following must be true.
1. you have to define Discont ind= 1, and followup material in MRP VIEW,
2. Both Discont item and followup items should have same base unit of measure.
3. When BOM of Header Material creation, discontinuation data is maintained for the discontinued item and follow-up data is maintained for the follow-up item -in CS01.
4. Then you have to assign some value for Discontinuation Group in "Discontinuation Data" for your Discot item in BOM. -in CS01
5. Then create a followup group with same value of Discont Group for yourFollowup item -in CS01.
During the MRP run the Dependent requirements of header material will be transferred to Followup item if it is not enough stock of Discont item.
Please check your Discont data has defined in BOM. The value of Discont group and follow group should be same.
please letus know for further doubts...

Consideration of stock of discontinued FG or trading material during MRP Run

There is an functionality of follow up material for component. I would like to know if there is any similar option available for finished goods or trading materials.
I am doing procurement planning for externally procured Trading materials. Now my previous material A is being replaced by material B. Therefore all the planned independent requirement is available in system only for B. But still there is some stock available for material A. How can it be considered during MRP run for material B.
Example,
Material A:
On Hand Stock = 100
Planned Independent Req. = 0
Material B:
On Hand Stock = 300
Planned Independent Req. = 1000
In this case if we run MRP for material B, how we ask system to plan Purchase Requisitions for 600 instead of 700 for material B, considering stock of material A.

Hello
Please refer to the following SAP note:
43636 - Discontinued parts
This note provides a detailed explanation of the system standard design of the usage of discontinued parts with material requiremenst planning and the most common questions about this issue.
The following information is provided on this note regarding the PIRs:
2. Planned independent requirements and forecast requirements are not redirected.
Explanation: Planned independent requirements after the effective-out date are not redirected but are provided with an exception message in the MRP list stating that they cannot be included in the availability check. Planned independent requirements and forecast requirements are therefore displayed in the MRP list and in the stock/requirements list. However, they do not influence planning
