MRPgenerated requisitions and MRP type =VB

Hi Gurus,
I have the following question.
IF a material has the MRP type VB=manual reorder point planning, then when the stock falls below the reorder point, MRP generates purchase requisitions. For eg, on May 1st, MRP generated a requistion of 100 units of one material. Now, if no PO is created or no goods receipt done on May 1st of that material, will MRP run on the next day will create one more requistion of 100 units? Or there will be no requistion generated by MRP, as there is already a requistion of required qty sitting there?
Thanks,
Kumar

Dear Kumar,
MRP run is as per the business requirements and it can be run daily or weekly or monthly (or individually for a material using
MD02.).In your case since already one PR for the required quantity has been existing in the system,when MRP is run on
the next day the system does not create any additonal PR for 100 quantity,and if you run with a MRP control parameter with
value 3 for planning type - delete and recreate planning data,then the system will delete the old PR and generates a new PR for
the same 100 quantity.
Check and revert

Item category (Customized )ZJT1 and MRP type for material is not allowed

Hi Guys,
When i try to create the order i see the error as item category and MRP type of the material is not allowed.
I checked in Vov5 table, i could observe that Schedule line category is maintained.
Could you please help us in resolving this..
Thanks and regards,
Rahul

Hi,
Please assign the Item Category ZJTI and MRP type (for eg: PD) assigned to the schedule line category in IMG under Sales and Distribution--> Sales ---> Schedule line -->Assign schedule line
Hope this resolve your issue

Item Category and MRP type for material is not allowed

Hello all,
I got a Error Message:
Transaction Z113 is not defined (Message no. V1347)
Diagnosis
This combination of item category Z113 and MRP type for material is not allowed.
System response
The system does not allow further processing of this item.
Procedure
Check your entry.
You can display the combination defined in table TVEPZ, which controls scheduling line category determination, and change it as required if you have the authorization to do so. The MRP type for the material may be changed in the material master.
The SD Configuration seems all right, I have:
Sls Doc Type (VOV8) ZA9 (no delivery type assigned)
Item Category (VOV7) Z113
Assigs Sls Doc & Item Ctgry (VOV4) ZA9/ZNOR/blank/blanl/Z113
ZNOR = Std Item-Av. chck Del
ZNOR defined in MM03/Sls Org 2
Define Schedule Line (VOV6) = Z7 (without delivery)
Z7 has FLAG on Prod Allocation
Assign Schedule Line (VOV5) = Z113/ND/Z7
At table: TVEPZ
I have the entry: Z113/ND/Z7
Guys, what would?
Please help me out because I am stuck in this issue.
Thanks a lot,
Barbara

Barbara, this may be tied to Strategy Group on the Material Master (I can't read enough into the detail)
Item Category determination + MRP Type for your schedule line type ties to a Sched. Line category(this you know)
New Rqmts class gets tied to a Rqmts Type
New Rqmts Type gets assigned to rqmts class
Strategy, assign the Rqmts Type to it
Strategy Group, Assign the Strategy to it
MM02 [MRP3 view] strategy group should be the one that ties together (all the other ties
It may be something in this area that you need to trace through ?

Forecast and MRP type

Hi,
I am in the process of designing a system where there is one DC which gets all sales orders and one mfg plant whihc manufactures and then STOs the material to the DC. Would it be a good thing to have the same forecast for the same material in the same preiods in the DC and the mfg plant, with the sales orders consuming the DC forecast and the STO consumng the mfg plant forecast ? I cannot think of any other way for the DC to drive the demand to the mfg plant and the mfg plant working with this demand to begin manufacturing and component sourcing.
Also I ran a forecast with the MRP type PD. I was expecting VV to be the only MRP type which will allow forecast to be run but looks like PD allows forecast as well. Is that corrrect ?
Thanks

Hello GS
It is not necessary to define the forecast on both plants, only on the plant where the sales orders will be received. Then, on the material master, you define a special procurement type such as "production in alternative plant" or "stock transfer" and MRp will automatically redirect the requirements from the DC to the manufacturing plant.
Take a look on the following link for more details:
Multi-Plant/Site Planning - Material Requirements Planning (PP-MRP) - SAP Library
Yes, PD allows the forecast. If you want to know which MRP types allow the forecast, take a look on the MRP type customizing transaction OMDQ. There is a setting where you define if the forecast is optional, mandatory or not allowed for the MRP type.

Purchase Requisition and MRP

Hi All,
When we Run MRP, system will create the requirement.
As in case of Production Order , FIRM indicator is there for order confirmation.
But for purchase requisition there is no such confirmation tab i observed.
Is there any facility there any such tab/tick available in PR which FIRM the requirement.
As my requirement is when i run MRP say today for certain SO item system give me the requirement of say 100 XYZ material code item. And creates the PR 450000010.My purchase department starts working ON THIS PR.
But next time when i run MRP, system again generate the PR 450000011 of 150( 100 from old and 50 new ) for same items XYZ..
But i observed that in this case previous PR 450000010 is deleted and new qty is updated in lates PR.
User dont want this , system should create new PR every time when i run MRP without deleting old one
Best Regards,
SAPMM

Hi,
The effect of it is that MRP won't be able to change the PR anymore.
SAP help (F1)
Firms the purchase requisition or delivery schedule line of a scheduling agreement, and determines that it cannot be automatically changed by the materials planning and control system.

MRP Type VV - Forecast Based Planning

Hi all,
My company would like to look at MRP Type "VV" - Forecast Based Planning (under Consumption-based Planning) for FG production materials.    I've read quite a bit about the concept and some based set up to how it works.   We would like to base Planned Orders > Production Orders based on this type of forecast planning.   It seem that SAP advises this kind of plannig for Raw Materials but not FG.   Anyway, what I really need to know are the specifics of how you set up the master data (in the Material Master) to properly execute this type of MRP: like....
MRP Type: VV
Lot Size: EX
Period Ind: W
Availability Check: 02
Forecast Period:   12
Periods per Season: 12
Historical periods: 60
other fields I'm not sure......
RP Profile: ??
Forecat Profile: ??
what else......?
Also, what is the recommended approach to convert this forecast plan into Planned requirements to be converted to Production Orders?
I appreciate any further information I can get on MRP Type "VV" and how it works.   I appreciate your input!

Thanks for the info nudratmaab.    Can you provide further data on what to expect given this forecast.....say I pick MVGA (Moving Average Forecast)? So I enter some consumption (say last 12 months) and run forecast (MP38).    The MD04 shows the average requirement per "W" bucket:
02/23/2012     ForReq     W 08/2012                16-
02/27/2012     ForReq     W 09/2012               116-
03/05/2012     ForReq     W 10/2012               116-
03/12/2012     ForReq     W 11/2012               116-
03/19/2012     ForReq     W 12/2012               116-
03/26/2012     ForReq     W 13/2012               116-
04/02/2012     ForReq     W 14/2012               116-
04/09/2012     ForReq     W 15/2012               116-
04/16/2012     ForReq     W 16/2012               116-
04/23/2012     ForReq     W 17/2012               116-
04/30/2012     ForReq     W 18/2012               116-
05/07/2012     ForReq     W 19/2012               116-
The next part is where it is a little foggy for me.   For "VV" do I run WRP1 (Replenishment) or do I run MD02/ 03 (MRP) and then what is the ForReq converted to (or does it even convert)?   I'm looking to implement this for Production Planning Requirements for Finished Produced products (I need them to convert to PldOrd (Planned Orders) to be converted to PrdOrd (Production Orders) by production scheduler.
The second part of this is the Raw Material (BOM component) associated with these Finished Goods. THese BOM components are set up as MRP Type "PD" and Lot size "EX" and I was hoping that the FG MRP run would also do BOM explosion and drive requirements for the Raw Material as well.....I'm not seeing that.
I need professional / expert to tell me how this works:    So MRP Type "VV" & Lot Size "EX" for the Finished Goods.......and MRP TYpe "PD" & Lot Size "EX" for the Raw Material (BOM Component).....
THanks again!!

Default lot size for MRP type

Hi,
Can we set default Lot size for MRP type ?
Regards
Karthik

Dear,
Yes you can do it by creating material master with MRP Pofile.
First you need to create MRP Pofile in MMD1 where you need to define the LOT SIZE and MRP TYPE which you want then make these value as Fix Value.
Then Create material master MM01 with this MRP Profile and check your result.

Difference between MRP Type

Hi Experts:
Anybody can explain me about Types P1, P2, P3, P4?
Thanks.
Diego

Please check this..
[http://help.sap.com/printdocu/core/Print46c/en/data/pdf/PPMRP/PPMRP.pdf]
And
MRp Type P1 or M1:
Ans: THe order proposal that lies within the planning time fence is firmed automatically as soon as its date lies at least one day before the finish date of the planning time fence. The date of new order proposals that are actually created in the planning time fence are rescheduled out to the end of the planning time fence. Therefore, these new order proposals are not firmed
MRP type P2 or M2:
Ans: An order proposal that lies within the planning time fence is automatically firmed as soon as its date lies at least one day before the end of the planning time fence. The system does not create any new order proposals within the planning time fence. That is, the shortage situation is not adjusted within the planning time fence.
MRP type P3 or M3:
Ans: Order proposals that lie within the planning time fence are not firmed automatically. The order proposals required to cover the requirements are moved to the end of the planning time fence
MRP type P4 or M4:
Within the planning time fence, the system creates no order proposals automatically. That is, the shortage situation is not adjusted within the planning time fence.
M4 is to classify the MS parts and P4 is for normal MRP items. BOm will be exploded in both cases to lower levels if procurement proposals created within or outside the time fence.

MRP is not generating purchase requisitions consistently for MRP type VB

Issue: When executing consumption based MRP in ECC 6.0 using the following parameters; purchase requisitions are not created for all material with stocks below max stock levels. In other words requisitions are created incase of some materials and requisitions are not created for others.
u2022     MRP type VB ( manual reorder point) with reorder point qty
u2022     Lot size HB with Max stock level
u2022     Procurement type F (external procurement).
Additional info: Some of these materials are batch managed and results are inconsistence whether it is batch managed or not.
Regards
Sai

I checked that and planning file entry is created.
Example 1: MRP is not working.
MRP type = VB
Lot size =HB
Procurement type= F
Material # = 1200045
Reorder point =30
Max stock level = 300
Available qty = 139
No PRs are existing before MRP.
MRP is expected to create PR for qty 161 (300-139= 161)
Example 2 : MRP is working.
MRP type = VB
Lot size =HB
Procurement type= F
Material # = 1200052
Reorder point =100
Max stock level = 1000
Available qty = 87
MRP created PR qty of 913 and results are as expected.
MRP is expected to create PR for qty 161 (1000-87= 913
NOTE: I am directly creating Purchase requisitions by selecting creation Purchase Requisitions Indicator =1 during MD01/MD02 trxs . Not creating any planned orders.

MRP Type P1 and late firm schedule lines

Hello All,
     We are using MRP Type P1 which firms our schedule agreement schedule lines within the planning time fence (as desired). However, sometimes the supplier is late on delivery and the firm schedule line goes into the past.
     Is it possible to have MRP move the firm schedule line delivery date to today instead of going into the past?
     Thank you,
     Jerry

Hi ,
Bring process forward (reschedule in)
Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
It does not take in to account the GR processing time and it is purely based on the stock requirement date , parameters in Procurement and Scheduling in the Material Master
So it will consume the requirement backward scheduling and bring the Process forward.
Kumar which strategy are you using ? scheduling agreement is of weekly , daily or monthly bucket ?
How many days SA bring to Production and How many days SA for forecast you are doing ?
Are you using any Program to convert these SA in to PIR and upload ( using any program ) .

MRP type for two different types requirments( Sale order and PIRs)

Dear All,
We have requirment some materials we have sales order and PIRs. For sales order we want to consider with "MRP type" as PD and PIR we want to consider "MRP type" as VB manual reorder point planning.
Is there any stadard solution.
If standard solution not possible also poivde some inputs on enhancement.
Regards
Sailendra
Edited by: nivedita yadav on May 7, 2010 2:31 PM

Sailendra,
your post is confusing, how you want to different MRP type for same material?
and why its needed?
1) you can use MRP type PD , and incoming sales order will search in existing stock or will create procurement proposal ( depends upon what strategy you are using)
2) If you are using VB then when ever you stock will fall below the reorder point you maintained in material master , system will create new procurement proposal, here the manual means the value you need to maintained manualy for reorder point and safety stock.
In automatic reorder point planning, both the reorder level and the safety stock level are determined by the integrated forecasting program.
The system uses past consumption data (historical data) to forecast future requirements. The system then uses these forecast values to calculate the reorder level and the safety stock level, taking the service level, which is specified by the MRP controller, and the material's replenishment lead time into account, and transfers them to the material master.
hope it will help you.

Delivery type "LB" and MRP

Hi All
I work on the APO side and iam not thorough with MM . I have a question about the subcontracting scenario .
We provide components to the subcontractor who then makes the finished products and ships them to our plant. Let us assume we have a subcontracting requirement for 100 CS. We now create a delivery (ME2o) to the subcontractor for 100 CS ( delivery type LB) . When we look at MD04 the delivery created for 100 CS is not offsetting the subcontracting requirement of 100 CS. So we now have a demand of 100 + 100 = 200 CS which is actually not the case. Is this a standard SAP behaviour ?
I believe whenever we issue goods to the vendor the stock at subcontractor location (MatSub) increases and the dependent demand gets offset by stock at subcontractor location . But why doesnt a delivery to the vendor offset the dependent demand ? Please help
Thanks
Saradha

Hi ,
I think planning strategy group plays a role in consuming the requirements along with MRP type (defined at material level)
check out MRP3 view -> Planning , Strategy group.

Best MRP type and strategy to run MRP for component using PIR and forecast

Hi Experts,
I want to run MRP for Component parts. I need to run MRP based on Planned independent requirements and Forecast Data.
Which is the best suited MRP type and strategy.
Please help to share bestpractices if any. thank you.
Rayudu

Hi,
is the components you are talking are Semi finished materials or Raw materials and Packing materials which are procured from vendors ???....
It is not a good idea to maintain planning strategy for Components which are part of BOM...these materials are automatically planned when the header materials of these components are planned....
If these components are not part of any BOM then you can try the option of using forecast based planning.. MRP type VV and maintain the forecasting view in the material master
You can also explore the option of consumption based planning like manual or automatic reorder point planning...
Thanks
Kumar

MRP Type and procurement type tabs in mmd

Hello Experts,
I was trying to check the MRP Type for a material master.
In MM01, I could not locate such a tab. I think I have seen it before.
I have entered most of the selection info like Material code etc.
Or is it that MRP type is not visible from material master?
What if its blank?
I check the MARC table for the material code and the MRP type is blank.
Also, in which tab can I maintain the procurement type? Could not find such a field in mmd.
Have a nice day everyone.
regards
Bass

Hi,
MRP type and Procurement type are under tab MRP 1 & MRP 2 respectively in material master.
Check MRP1/2/3/4 tabs all information you need is there.
