Background mrp in mdbt

i want to run mrp in background for my new plant.
i created variant for that plant and sched weekly and also i defined parallel processing in MRP. but mrp happened without selection of material???
there is no error msg in list of scheduled request...

Hi Prakash,
In MDBT transacton choose the variant & then click the "Display scheduling" tab. Check the status against the date, if it is "Finished". Then choose this row & click results.
Now choose the ABAP List icon under "Type". Here the MRP run result will be displayed.
Check the processing key used, If this is the first time then use NEUPL, else set as NETCH & then run.
If MRP is active for the plant & planning file entries exist, then the materials in the plant are to be considered during MRP run.
You can check the MRP run results for a single material using transaction MD02/MD03.

Selection screen in background MRP

Hi all,
Can anyone please tell me what is the meaning of 'selection screen', in background MRP variant? What does it contains and what is its significance?
Thanks in advance
Sumeet

Hi,
In a variant there are several fields in the selection screen, the variant is saved with a set of these field values.
In the case of MDBT, you can create several varinats for different materials or Plants and then execute those varinats whenver you need.
Basically the varinat caoncept is associated with Back ground jobs and also user specific entries.
Suppose every time you do not want to repeatedly enter the same field values , you can use these varinats.
Reward if you like it.

Problem with Back ground MRP Run (MDBT) or MD01

Hello SAP Experts,
Issue :- Material is not considering during Automatic back ground MRP run ( MDBT or MD01)
But when we run MRP in forground (MD02) system is considering the material.
we have checked both the selection parameter are same for MD01 and MD02 .
can you help us on this issue ?
Regards
Mahesh

Hi,
Problem is due to entry in Planing File is missing for that Material.
Go to MD21 and check whether Planing File entry is maintain for that Materiel.
If not then maintain it by T.code MD20 (Manual) or you can do it by using back Ground JOB - OMDU.

Reg:Background MRP Job

Hi friends,
i want to set background MRP job for my client.(Scenarion-MTO)
when they recieve the sales order then only the design people will prepare the BOM (TAKES 2 to 3 days to prepare BOM).
Now if the sales people create the sales order today..design people take 2-3 days to prepare BOM.
if i set daily MRP, the system wil genrate Planned order for incomplete BOM.
can we change the incomplete planned order BOM to our requirement...?
or is there any option in background tto restrict the creation of planned order for sales orders without complete BOM.
let me know.. thnx for everyone.

Dear ,
It is possible , if you keep the Schedule Line Item categoery in VA02-SCheudle lIne -CN-No MRP.
Or you can goto Reason for rejection option in Status field in VA02.
Just to add on that , in case of MTO cycle ,there are following steps :
1.Logging Enquiry for customer -VA11
2. You will logg Quotation-VA21 frist and will carry out the Unit costing if you do not able to finalise the BOM till the design gets approved or customer finalise
3.Then you will logg sales order based on the approval from custmer with refernce to quatation .At that point , you will be having BOM and routing based on design so that Sales Order will capatured the planned cost estimate .
4.Now , if you run MRP with out having any BOM , there will be any componenet planning execpt the header material .
But , if you have prepared you BOM after running MRP frist time and go back to sales order -VA02-Carry out Costing ( Sales Order -Extras -Costing -All green Flag ) and then finally realse the Dynamic credit check in vkm3 for next MRP run in MD02.
Here in the next time , you need to run MDO2-NETCH , 2,1,3,3 ( Delete and Re-create planning ) so that BOM will be updated with relevent planning of depedent .

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.

Any difference setting background MRP run in MDBT and SM37

Hello,
Just wander if there is any differences setting up MRP run in MDBT or in SM37 to run RMMRP000? This is to run MRP at plant level in background.
Thanks,
Lin-Lin

Hi,.
Both MDBT & SM37 are having same program (SAPLBTCH) . MDBT is Foreground job as well as Background job.
SM37 is only for Background job only.
Pls let me know any further clarification.

Current stock was 5 then system generate PR for 95 Unit as I expected. I have test this scenario in DEV server.
Same scenario I have mapped in Quality server. But when I start sheduling immediate in MDBT, system do not generate any PR
even if stock falls below min. level
Where is prolem?
Please help.

Dear ,
Thanks for your reply.
Can you please tell me what setting & MRP parameter has to check. Because I run same scenario in DEV server and did not found any problem. System had generate PR.

The problem about running MRP by MDBT

Hello everydody,
I encountered a strange problem in SAP system when I runned MRP by using MDBT.
Usually running MRP has two ways.First running MRP by using T-code MD02 ; second running MRP by using T-code MDBT in the background.In my SAP system,I used T-code MDBT to run MRP, and the MPR parameter is below:
Scope of planning
Plant                             2000
Processing key             NETCH
Create purchase req.      1
Schedule lines                 3
Create MRP list                1
Planning mode                 3
Scheduling                      1
Planning date             2010.06.30
Normally if I choosed the Planning mode 3 Delete and recreate planning data,then after running MRP ,the Plan orders' number and purchase requestions number should be changed and produced new numbers.
But I used T-code MDBT to run MRP, the Plan orders' number wasn't changed,the purchase requestions' number was changed. If I used T-code MD02 to run MRP, the parameter is the same as above.After running MRP,the plan orders' number and the purchase reequestions' number were changed.
I don't know how caused this happening.
Is there anybody who can help reslove this problem?
Thanks & Best regards!

Hi,Nikolai
I was spending vacation, i can't get that now, and i will send it to you as soon as possible,i think maybe that error occured beacause I updated the metadata from V 9.0.2 and imported it into the new version of Builder?

Change in background MRP time with EDI scenario for sale order booking

Hi All,
              I have a scenario where Sales orders are booked through EDI. Now because of some reasons duplicate orders are getting booked in SAP. Now users are manually deleting the duplicate sales orders.
          Now MRP is running at Night with duplicate orders in background. So users wanted to run MRP after deleting the duplicate SO.( i.e. during office Hrs)
         Should i change MRP timings to suit the user requirement? what will be the pros & cons if change MRP timings.will it throw errors in EDI.
Thanks & regards,
dev

Dear,
If you change the MRP run time for periodic job in MDBT it would not affect any where only system will create the procrument after MRP run only.
Please try to find out the reason why duplicate orders are getting booked?

How to stop Background MRP ?

Dear All,
I have run Plant MRP in background by MDBT for every minute.
that's why system is taking MRP run at every minute.
I have tried to stop it but it doesn't stop & caring out the MRP in background for every minute.
Please give me valuable input to stop it.
Thanks in advance.
Vijay Mankar

Vijay,
Use transaction SM37, in the intial screen input the program name and job name and execute the transtion with "Scheduled" status check box active. Once you get the scheduled job go to change mode from menu bar Job--->Change or Ctrl+F11. In the change job screen hit the "start condition" function button and here you change the frequency of this the periodic job.

Background MRP Run Some times Planned orders are not generating.

Dear All,
We run MRP in the background at plant level once in a month. Some time we do not get planned order for the material in MD04. Than we run MRP (Selected material only) manually through MD01 considering MRP control parameter 13132.Than only we get planned order. Plesae let me know why it happens? Please give your comments on this.
Thanks & Regards
Kundan Kumar

Dear Kundan Kumar,
First check the output list or the results of MRP run in SM37,find out for how many materials it has
throwned out error,I hope in this list you can find out the materials.
Then the next step you have to check once again the material master settings.
Instead of running in MD02,first check whether was there any issue in master data,or if this happening
repeatedly for the same materials and work around.

Unfirmed purchase reqs not getting cancelled in the background MRP run

Good morning,
The system has created Purchase requisitions for 2010 due to the setting in the MRP run. we want to change it to planned orders outside the Vendor lead time and when i run a REGEN MRP with setting 2 (Purchase requisitions in opening period) its not happening. When i run indivudual MRP with MD03 with the same setting its alright, purchase requisitions are deleted and its converted into Planned orders. Can anyone please throw some light on to make backgrouond MRP run delete the Purchase requisition and create planned orders.

Jags,
You must delete the offensive PRs first. Regardless of the MRP settings, MRP will still decide that the PRs are valid and will leave them alone. It will not 'change' them into planned orders.
Run Regenerative MRP with your new settings (Create purchase reqs as '2') but also run your MRP in planning mode '3', delete and recreate planning data. It will delete all existing unfixed purchase requisitions, and then run MRP.

MDBT : MRP RUN Problem

I have one storeage locaion for which i want to tun MRP run in backgruond .
Now i have cerated MRP area (STORE) as stoarge location asssigne th erespective storge location there.
Now i created scop of planning & i assigne tthat MRP area as "STORE"to scope of planning.
Now cerated varaint as "CONSUMPTION"and in scope of plalning i selcetd the scope of planing as my MRP area and saved the variant .
Now all material under this area are cinsumption baed material means everyone has MRP type as VB, reordre point and lot siza as HB, max lot qty and STORE as MRP area in material master.
NOw in MDBT i selcted the variant and click on start inmmediate i m getting mesage as "Request with variant CONSUMPTION Started"
If i see MD04 til no requirenment is genrtaed with this Run ??
1. Please tel ..where i ned to corect
2. Is there any mesage after background MRP executed ;like in MD02 planning result screen .

Dear,
Please check whether planning file entry exists in MD21 also check MDAB & MDRE ?
or run program RMMRP000.
Please note With MRP type VB (Manual Reorder Point Planing) system will not consider Dependent requirement or any other reservation.
It will take care about only Reorder point.
If You have set reorder point of 100 Nos.
And dependent requirement is of 35 Nos , and available stock is 90 Nos. then at the time of MRP run system will generate PR of 10 Nos only just to cover that less qty than the reorder point of 100 Nos.So there is nothing wrong in your case.
If you want to concider Dependent requirement also during Planing run then you have to change MRP type VB to PD then check.

MRP Background & Online

What is MRP Background & Online? MRP i.e. MD02/MD01 is background or online?

Hi
You can run MRP either online or Background
MD01 - online for the total plant
MD02- online for material wise
Online planning
The system carries out total planning for the plant selected or for the scope of planning you have defined. The individual plants or MRP areas are planned in the sequence defined.
When you have completed the planning run you receive statistics with information on the scope of planning, exceptional situations and terminations. You can also see how much time is required for the planning run in total and for planning the individual materials.
To limit the scope of these statistics you can set the number of materials used, in Customizing for MRP under Activate runtime statistics.
Background planning
Tcode MDBT
If you carry out the total planning in the background, you can print these statistics.
If you have selected the field Display material list in the initial screen of the planning run, the list of the materials planned is displayed above the statistics. If you position the cursor on a specific material in the list and choose MRP list or Stock/ requirements list, this takes you directly to the appropriate list and from there you can test the planning result.
Starting from the Material Requirements Planning node, choose Planning ® Total planning ® As background job.
The Total planning: Variants screen appears.
Choose Create variant.
The variant contains the control parameters for the total planning run.
Enter a name for the variant and choose Create.
The system displays the Variants: change screen assignment dialog box. The system recommends the BATCH structure for MRP run screen.
Choose Continue.
The recommendation is copied and this takes you to the initial screen for the total planning run.
Enter the control parameters that the system is to use during the total planning run (see Control Parameters for the Planning Run) and, if you work with scope of planning, select the Parallel processing field.
Choose Attributes.
The ABAP: Save Attributes of Variant XXX: screen appears.
Enter a description for the variant in the Description field and choose .
This takes you to the initial screen for the total planning run again.
Choose Variants ® Exit.
The Total planning: Variants screen appears again.
Position the cursor on the variant and choose Schedule job.
The Total Planning Scheduling: Start Time screen appears.
You define whether the variant created is to be scheduled just once or periodically.
Result
If you choose Schedule once, the planning run is carried out once on the date that you have specified and with the control parameters that you defined in the variant.
If you choose Schedule periodically, the total planning run is repeated at regular intervals.
If you run the total planning run in background mode, you can print out the protocol and the resulting statistics.
Hope you are clear
If so, Pls reward your points
regards
Vijay

MRP issue -reg

Hi Friends,
The quiery is like this
MD01 is scheduled as a background job using MDBT transaction . Here values are maintained for MRP control parameters which appear on MD01 initial screen like
Processing key
Create purchase req
Schedule lines
Create MRP list
Planning mode
Scheduling
Planning date   .
Though here it is given that no schedule lines , MRP output is giving schedules for BOM components
quiery is which control parameters are preferred while system is executing MRP   ,
1.The Plant parameters which are maintained at plant level
   thropugh OPPQ
2. The Plant parameters which are maintained at MRP Group
     level thropugh OPPR
3. The MRP control parameters entered in MD01 initial screen
4. Master data maintained like planeed delivery time , etc... for
    material in material master
another doubt is while running how the system considers the MRP control parameters pertaining to the BOM header parts and BOM components
regards,
Madhu Kiran

Hi,
For MD01, system will check MRP group parameters for particular material. MRP group creation indicator overwrite the initial screen of MD01 creation indicator.
If MRP group not found system will use initial screen of creation indicator.
For MD02, system will overwrite MRP group creation indicator. MD02 initial screen indicator has priority over MRp group.
For your last question also system will work as above.
Check the following taken from SAP Help.
The creation indicator for purchase requisitions is only valid if the MRP group does not override it. The creation indicator for scheduling agreement schedule lines is only valid if the MRP group or the plant entry in Customizing does not override it (see Creation Indicators in the Initial Screen and the MRP Group ).
In single-item planning the creation indicators in the initial screen overwrite the creation indicators in the MRP group (see Creation Indicators in the Initial Screen and the MRP Group).
Regards,
Dharma
