MRP Questions

1) A specific SKU (Material number) is used by 2 different parts of the business (it is sold as a spare part and it is used to repair units in house). Hence, this part has primary and secondary requirements (Independent & dependent demand). The inventory is kept separate in 2 different bins/locations. The challenge is to plan the replenishment of this material in MRP. MRP will look at the combined requirements and generate one Purchase Requisition that in turn is converted to a Purchase Order, which then is received (in bound). The problem is that if we want to keep them separate in storage we need to somehow separate the inventory. Is there a way to get MRP to plan this material separately depending on the source of the requirement? I would not want to create a separate Plant to do this.
2) The other question is as follows:
I have 3 plants, I have inventory for a given SKU at each of the plants. The forecast however is at a u201CPlanning Plantu201D (4th plant) at an aggregated level for all 3 plants and I want to carry out a MRP calculation at the planning plant to determine how much I need to buy (purchase Requisition) for all 3 plants combined.
I would really appreciate your input on this.
Thank you.

Hi,
For your first question, can you carry out Storage Location level MRP?
For example, The independent requirements (Spare Sale) generated through Sale Order will be triggered at Finished Goods Store. For Dependent Requirement, the requirement will be triggered at General Store.

MPS and MRP question

Hi all,
There are two kinds of planning run (i.e. MPS and MRP). I have few questions on this.
1 - Do I need to setup two background jobs, one for MPS job, and another follow by MRP job, in the system?
2 - Can I just run MPS using MD40 (total MPS run) without perform MRP run (i.e. using any of the MD02)?
3 - Does MPS ONLY plan one level only? in another word, all the second level onward will require another separate MRP run to show all the subsequent level dependent requirement?
4 - if there is one FG, and it has 2nd level of semi-FG bom compenent, the semi-FG has another level of semi-FG and subseuqently Raw material level. In this kind of scenario with many level, it is good practise and it SHOULD use MPS to first plan for the first level FG? and later subsquent level use MRP to plan? Am I correct?
thanks.

Hi,
No,
You can MD40 and then MD02
Usually Only those materials which affect companies profit will be taken for MPS, hence few materials will be available for A importance, so you run level by level for MPS, rest will run under MD02, it depends on the business process.
When running MRP using transaction MD02 and MD41, what the difference should be?
There is no difference in the processing logic as such. The only difference is that MPS only acts on materials with an MRP type relevant to MPS (e.g. M0, M1, etc...), and MRP acts on materials with an MRP type relevant to MRP (e.g. PD). How the materials are processed is exactly the same.
This functionality allows you to run MRP for 2 sets of materials separately (and with a different frequency).
For example, some businesses may do planning for their finished goods once per week, but would want to run MRP for their
components daily (although this is generally not necessary with SAP). So, for this example, you would define all finished goods with an MRP type relevant for MPS, and all components with an MRP relevant.
Basically, MPS is a form of MRP that concentrates planning on parts or products that greatly influence the company profits or those that require critical resources. Items marked as master schedule items can be finished goods, assemblies or raw materials. These items are selected for separate MPS run that takes place before the MRP planning run. MPS run is executed without any BOM explosion. This is to allow the MRP controller to ensure that the master schedule items are correctly planned before any detailed MRP run take place.
As you can see, there are not too differences if you review MRP and MPS isolated, but lets think the BIG PICTURE, and can find the difference is just an procedure stuff:
1: RUN MPS (tcode: MD40). SAP do the planning run multilevel, also considering the MRP materials.
2: Do the the necesary MANUAL changes in your MPS materials Planned Orders, remember that the planning run is "JUST AN ADVICE" and never can replace the human decision. Here, you have your MPS Plan, and also the consumtion Plan (dependant requirements)
3: Then, with the dependant requirements OK (acording to MPS's Materials Planned Orders), do MRP RUN (tcode: MD01). The MRP run dont change the MPS plan.
The idea of MPS and MRP is to "separate" materials, in order you can run "masive process" in order. The algorith of mps and mrp are the same. Both work with the PlanTime Fences and Fixation types, rescheduling is the same, and so on.

MRP question (make To order)

Hello all,
We have a case where Finished Goods are required directly for a Sales Order. MRP runs for the Finished Goods, planned orders create for PP and the relevant raw materials will need to be procured. There are cases where some of those materials are already in the warehouse as they are procured on a constant basis since they are the basis for many finished goods. There is a safety stock MRP running for them.
Any suggestions as to what is the best way to manage this scenario?

Dear Ioannis,
Yes maintain safety stock in MRP - 2 for ROH
Also maintain indi/coll indicator as 2 in MRP - 4 view

MRP question

I have created a batch job to run MRP, I have noticed that the MRP run is not planning some materials!
I have a material with a contstant demand, this is called off via schedule lines, if I run the Batch Job MRP I get no planning, if I run Single item Multi level it works.
The Planning time fence is OK, does any one have any suggestions?
Kind regards

What do you mean by "called off via schedule lines"?
Please check the MRP parameters in both transaction MDBT and MD02/MD01
Scope of planning
Plant
Processing key
Create purchase req.
Schedule lines
Create MRP list
Planning mode
Scheduling
Planning date
Display material list
Parallel processing
User exit key
User exit parameters
Am sure there will be difference.

Planning time fence and MRP question

Good morning,
We have the following requirement:-
1. We want the Planning time fence to move once a week (by 1 week)
2. If we have a schedule line at the end of the Planning time fence, we want this to move inside the planning time fence (as per step 1)
3. Put a fixing indicator on anything that falls into the Planning time fence (as per step 1).
Thanks in advance

Material type questions and fields on the MRP tabs

Hi Gurus,
Can anybody please answer these questiosn for me?
1) material types determine what views will be created in the materil master right?
2) for materail types can we have procurement type as F, E or both?
3) MRP controller and purchasing group fileds on the material master, what are their significance? like which field will take importance in what ccase is my questions?
Can anybody please help me in answering these
thanks
Anmusha

All the materials which can be produce inhouse that only can have Procurement type E and The materials which can be procured externally always can have F.
The materials which can be manufactured inhouse as well as procure from external source can have both type procurement
eg. Raw material will always have F
Finish goods will have E
and SEMI finish can have both procurement type
the reason you can prodice inhouse, procure from outside or you can do sub contracting.
Yes, the material should have MRP controller to pull in MD07

Question on MRP lot size.

Greetings Gurus
I have a question on running MRP and lot size. We would like to run MRP for our horizon period of 4 months.
Basically, we want SAP to create a single purchase requisition for any requirements that falls within this 4 month period,
But any requirements that fall outside of this, we want SAP to exclude (horizon MRP group set to 4 months)
I am having difficulty making this happen.
I think it may have to do with my lot size definition. Icopied lot size MB and changed the no of periods to 4.
But when I run MRP (@MD03, Processing key = NETPL, Create PR= 1, DelScd = 3, everything else = 1),
it creates 2 requisitions, one for theimmediate 4 month horizon period, but then it creates another requisition for the next 4 month period.
When I set my lot size to MB, it creates everything within the single 4 month horizon period as I expect, but it breaks it up into
requisitions by month.
Any advice on how I can accomplish this?
Thanks in advance
Regards
Ken

Hi Ken,
Txn Code OMI4, make a copy of lot size MB to say Z3 & give a description as required, then change the value of No. of periods to 3 & save. Now you can assign this in your Material Master.
you need copy as Z3 from MB and also assigned to material master (view MRP1), and the short term parameters as per below:
- No of period = 4
- Lot size proced = P
- Lot size ind = M
- Scheduling = 1, else <blank>
For further any issues pls share with us.

Questions Regarding MRP

I had a couple of questions regarding MRP. Will be glad if you could answer these:
Is it possible to remove the 'in house production time' & 'planned delivery time' from MRP?If it is possible, what will be the impact of removing the above?
Can we change the start/end date of the factory calendar, with or without removing the above?
Please answer the above.
Thank you very much.
Regards

If we keep inhouse production time and planned delivery time as zero, will this have any other impact?
Secondly, is it possible that we can manually change the start and end dates which are suggested electronically by SAP?
As I said earlier if you keep in house production time as zero system still would allow to create a material master record and based on this MRP calculates the dates required for any planned order in basic scheduling.
If you keep this as zero you order basic start and end basic date would be on same day.
It is recommended to maintain the no days required for in house produced material in MRP2 or in WS view or you need to enter the setup, tear down, processing, and inter operation times so that based on these values, the system determines the in-house production time on the basis of lot size.
Same way for Planned Delivery Time, only the difference in both of these fields are In house Production time considers the FC where as Planned delivery time considers the calendar days.
For your 2nd Question if you change the system proposed dates in any planned order based on the scheduling type start and end dates would be changes accordingly.

Question on Schedule Line category in Sales Order not relevant to MRP

Hi experts,
I want to know whether the sales order having any schedule line category like CP, CN, etc will not be relevant for MRP. In other words, If I do the MRP run for the Sales Order Requiremnt having any Schedule Line Category in particular will not generate any procurement proposals like Planned order/ Purchase Requisitions. Please advice me on the same.
Regards
Brijesh

Dear Brijesh,
Please find some info related to scheduled lines below,
The various schedule line categories are controlled in different ways:
The schedule line AT in inquiries is used only for information.
No requirements are transferred and no availability check is carried out for the schedule lines BN and CN.
Requirements are transferred and the availability of the material is checked for the schedule lines BP and CP.
No stocks are managed for the schedule line categories BT, CT and CX. No goods issue is posted for the categories BT and CT. However, goods issue is posted for CX.
The schedule line categories BV and CV are controlled in the same manner as the categories BN and CN. However, requirements can be passed on for analysis purposes.
Goods receipt is posted for the schedule line DN in a returns document.
The schedule line categories CN, CP, CT, and CV are relevant for delivery; the other schedule line categories are not.
*Control Elements for Schedule Line Categories
Different schedule line categories are permitted according to the sales document type and item category you are using. You can use control elements to tailor the schedule line categories to meet the special demands of your installation. You can also define new schedule line categories.
Hope this helps.
Thanks

A question about MRP.

Hello everybody
My Enviroment:
Primary and Physical Standby 's O.S: SLES 10 SP2
Primary and Physical Standby 's Database: Oracle 11g R1 U7
How can I start MRP on physical standby of automatic way after a database startup??
I 'm asking because when I restart standby 's server, Database start up without problem, but MRP doesn't start.
Thanks for helping

I already have a similar trigger.
CREATE TRIGGER CHECK_ERNIE_START AFTER STARTUP ON DATABASE
DECLARE
V_ROLE VARCHAR(30);
BEGIN
SELECT DATABASE_ROLE INTO V_ROLE FROM V$DATABASE;
IF V_ROLE = 'PRIMARY' THEN
DBMS_SERVICE.START_SERVICE('ernie');
ELSE
DBMS_SERVICE.STOP_SERVICE('ernie');
END IF;
END;
This example for a listener.Because I think you only want to do this on the Standby database. However its kind of catch-22 if you stop and think about it.
If the database was started I could determine the role before I started it!
Not sure I like the script idea with some sort of ROLE check first.
Best Regards

Mrp, mps questions.

1.Is it possible to increase a companies output by increasing the MPS. if not, why?
2. How does the system coordinate the individual item records and provide back schedule information?
3. What are some of the reasons for wanting to process the records in and MRP system frequently? Provide examples and consequence of delaying the processing of the information.

Deear,
LTP is used for plnning the production for comming year and budget cost for comming year. i.e. std cost restimation is calualted.
MRP/MPS are used to planning material/plant/multi plant level.
After demand is put in DC's then if the special procurement key is maintained in DC's so that when run MRP in DC's the requirement will be passed to production plant in the form of sto planned order.
Now we can run MRP/MPS sequencially in MD01- using scope of planning in which you can set the parameter such that which DC's MRP is run first, then which Manu plant MRP is run....
In DRP, after running MRP you can run DRP to see that that push pull scenario is run so that load balance is done in such a way that DC's requirement can be met by another DC or a manu plant. If stock is not avaialbe in one manu plant it will go to other, if not available then systen will create a planned order in one of the manu plant.
In APO we can optimise the whole cycle of push pull so that amany other constraint like cost also takne into account.
pl come back if required.

Question about MRP

Hi
In my company we have two plants 1000 and 1100. 1100 is assembling parts into end product, 1000 is producting the assembly parts. In 1100 we have set up SOP and in MD04 we have the LTP items. In 1100 we are using MRP for creating purch req. for parts that have the procurement type F and special procurement type set to have the stock transport order from plant 1000.
In 1000 we want to also use MRP to generate planned orders which we could convert to production orders. But we would want to have the MRP run to generate planned orders only according to created purchase orders (STO from 1000 to 1100). Currently when we tried to start MRP in 1000 we got planned orders for all purch req and Purch Ord.
I would be grateful for any hints and links that could help me to set up this MRP run to work as we want in this one plant (1000).
BR
Gracjan

Gracjan,
Easiest way is to remove the special procurement key in the material masters in the destination plant.
You can still create the STOs manually, once they are set up.
This way there will be no Purchase reqs sending demand from your 1100 plant to your 1000 plant, only STOs.
If this is unacceptable, then you will need a custom solution.

DB49.

Question - MRP

Hello Experts,
                      When running order recommendation for production orders,iam getting a error.

hiii Mansoor
             check your material for which you are running MRP Wizard , BOMS are available?
            check in bill of materials
                                                       Good Luck

MRP and Factory calender question

Hi all,
When MRP runs to replenish stock from planned orders using production planning and/or Purchasing (Planned orders to Requisitions or production orders), is it replenishing stock based on lead times in a 20 day per month (excluding SAT and SUN and company holiday) format or full calendars days? This would also be an input to contracts/agreements etc.
Please advise.

Hi ,
While planning MRP takes inhouse production time for inhouse materials and is calculated in work days which referes to actual working days from factory calendor.
normally for purcahsed parts, planned delivery time ( PDT) is maintained in material master and this is actual calendor days. This does not consider the actual holidays from factory calendor.

PP MRP order consume fcst question

here is an example:CTO1 and CTO2 has the same structure(history reason)and we plan on both CTO
         CTO1    CTO2
fcst    100       100
after get orders:
         CTO1    CTO2
fcst    100       100
order   150       10
since CTO1 order will only conusme CTO1's fcst..how can CTO1 orders consume CTO1 fcst first and continue to consume CTO2's fcst once CTO1 fcst are less than CTO1 oder(CTO1 fcst < CTO1 order)
Not sure if we can make it in SAP...Pls feel free to bring your comments...thanks very much..

CTO1 and CTO2 are a configurable materials (super BOM)..and the customer require model(MTM) orders will consume the fcst on these configurable materials(63 strategy Planning w.plng material w/o mke-to-ord)..
for example,CTO1 have 10 building block(like,HD,SP..)BB1,BB2,..BB10 while cusotmer order may only require BB1,BB2..and this customer order will conusme the fcst on this CTO1's BB1,BB2 fcst...
         fcst
BB1   100
BB2   100
BB10 100
customer order arrive:require BB1 10,BB2 10
           fcst     order reserve
BB1     90         10
BB2     90          10
BB10 100
We will only plan on CTO(super BOM)..and orders have detailed requirements..
Not sure if I make u understand...
Now we plan on CTO1 and CTO2(CTO1 has the same BOM structure as CTO2)
if a customer order comes,we hope the order will consume the fcst on CTO1 first,then consume CTO2...
