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.

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?
Thank you

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.

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.

Open Purchase Orders not considered as requirement for MRP Run

Hi ,
We are facing a issue of Open Purchase orders not appeared in Stock requirements list and also it is not considered as requirement for MRP Run against reservation.
As aresult for a reservation demand of 10 units we are ending with Open POs 10 units and a additional planned order 10 units.
Material Type : ERSA
MRP Type : PD (or VB)
Lot size : EX ( HB if MRP Type is VB)
Could you please throw some light to correct our settings to MRP to consider Open POs?

Can you check to see if there is a re-order point set up for this materia? That could be causing the problem too.

Sale Order MRP Run for All Order Line Items

Greetings...
I have One Sales Order , in which i have ten different Line Items .
Now I have to Run the MRP on basis of Created sales Order so that all Line items wi get consider insingle MRP Run on sales order base MRP Run.
How to take MRP Run of One Sale Order for all Line Items.???
In MD50 , we can have sales Order with Item..

In MD50 you can give only one item at a time.
Its a standard transaction meant to accomodate changes relevant for MRP after plant level MRP run related to specific sales order Item.
so either you need to do it multipal times by changing material or you need to go for MD02.
Please explain bussiness case in detail why you want to restrict your MRP run for items in a specific sales order.

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

MRP Run with User Exit key for Follow up material

Dear Gurus,
I want to run MRP only for followup materials by using User exit key. For example i have a material X(with discontinued Indicator as 1) and it's follow material is Y.
So we have a user exit key as ZFL, with coding as shown below. Now when i run MD01 with user exit key ZFL and parametre as 1, it only runs MRP for material X and not for material Y. What else we need to do so that when i run MD01 with user exit key ZFL, it shoudl consider both X and Y.
WHEN 'ZFL'.
DATA : BEGIN OF ITAB5 OCCURS 0,
KZAUS LIKE MT61D-KZAUS,
END OF ITAB5.
TRANSLATE USER_PAR TO UPPER CASE.
SPLIT USER_PAR AT ',' INTO TABLE ITAB5.
IF ITAB5[] IS INITIAL.
EXIT.
ENDIF.
CLEAR: NO_PLANNING, STOP_PLANNING.
READ TABLE ITAB5 WITH KEY KZAUS = MT61D-KZAUS.
IF SY-SUBRC <> 0.
NO_PLANNING = 'X'.
ENDIF.

Hi Kumar,
You can use either MRP Type, MRP Controller, MRP Group in this user exit to control the MRP run. For these set of Materials you have to assign any of same value or at least differentiate these material from other material. Then only you can control the MRP by using this user exit even though if you use different MRP Group and MRP Controller. In User Exit, you may have to add your dependent material's MRP Group/MRP Controller. Make sure that these set of materials are different than all other materials.
If you don't have any plan to run MRP for other materials then as per Ajit suggestion you make that material's MRP type as "ND". But, in your business case they may want to activate the MRP for all the material not now but may be latter.
Thanks

Hi
i wanted to just know about the Funtinality of Follow up material into Specialy MRP run.
Whether system will consider the parrallal Material Stock and Open PO if we are considering the
A (1 nos) FG is having X (1 nos) Material is current part and Y is followup material for the Same with Indicator 1.
Suppose X-200 nos and Y -700 nos (Open PO also 200 nos)
then after MRP run suppose for A FG requirment is 1500 than is system will consider the Y-700 + Y-200(Open PO) and give the PR for X is only 400.
