Scheduling in MRP

Hi, one fert req one roh to maufacture. we have mentioned 2 days for fert mat as in-house prod days, 2 days as pland delivery days for roh. after mrp run, how system will schedule the dates? pls explain. we know delivery date in sales order.

Dear Yadav,
As per the scheduling parameters given to OPU5 (for plan orders) scheduling takes place in MRP
There are two types of Schedulings
1) basic date scheduling
2) lead time scheduling
basic date scheduling - in initial parameters of MRP if u give scheduling as basic scheduling then system takes the data from material master i.e in-house production time. in this scheduling capacity requirments are not generated
lead time scheduling - in initial parameters of MRP if u give scheduling as lead time scheduling then system takes data from Routing to calculate dates. here cacity requirments are generated.
Coming to dates
if ur maiantaing in-house production time as 2 days for FERT & 2 days as plan delevery time (without GR processing Time)
Then system does backward scheduling as (if u maintain backward scheduling in OPU5)
so total days for FERT to be availble will be 18.07.2009 (starting from today)

Scheduling in MRP Run MD02

dear all,
i still confuse for using scheduling in MRP run MD02,
what is the use of using both scheduling type "1" and type "2"?
because if i run the MRP using scheduling type 2, after i generate the planned order, then i can see the capacity planning evaluation,
but not if i run scheduling type 1
if i run the scheduling type 1, how can i analyze the capacity planning?
until now, i always run the scheduling type 2, because i think it is more useful to run scheduling type 2,
so what is the plus and the minus using scheduling type 1 or type 2?
best regards,
MARUFAT

Hi,
In simple words:
The main difference between scheduling type 1 (Basic date scheduling) & Scheduling type 2 (Lead time scheduling & Capacity requirements) is from which records MRP reads the values.
Basic dates is more like a rough scheduling where the values are read from the material master & the exact operation times are not considered or capacity requirements generated.
Lead time scheduling is more precise meaning for each in-house produced material it reads the routing & checks the time maintained for each operation, it then calculates the exact times for each operation based on the working days, shift timings, breaks & also generates capacity requirements.
Now what is the criteria to select... it depends on the business requirement. But the data maintenance for Scheduling type 2 is higher as compared to Scheduling type 1.
What is the benefit for going for Scheduling type 2.... well it gives you a clear picture on your production planning process & how much capacity is required, whether you have the requisite capacity etc etc.
Basic date scheduling is preferred when you do not want such fine control on your production planning process.
For more info refer to SAP help, it should make it more clear.

Vivek

Planned order scheduling in mrp

hi
i selected schedule margine key with 0 flots (key000)
and chossed *LEED TIME SCHEDULING (in mrp controll parameters :-scheduling 2 at MD02 )
how the reduction strategy helps in this case ,casue i am doing lead time scheduling system has to consider only routing time ??? right ??
plz suggest how to arrest message 64
regards
sasikanth
message 64 diagnosis enclosed
64: Production finish after order finish (P4)
Message no. MD427
Diagnosis
The production finish date calculated using the routing lies after the order finish date that was calculated using the in-house processing time in the material master record.
As the system uses the order finish date in the planning run, this situation may lead to material shortages if production is not finished until the production finish date calculated by the system.
System Response
This exception is displayed in the MRP list and in the current stock/requirements list.
Procedure
Check the times in the material master record and in the routing.
Check whether the order has to be rescheduled in.

BADI or User Exit for scheduling in MRP

Hello,
I am searching a possibility to influence the scheduling of planned orders, when they are created in the MRP run. There exists a BADI which is called when creating planned orders manually, but not in MRP. Its name is MD_PLDORD_SCHEDULING
Does anybody know about such an alternative for scheduling in MRP?
Thanks in advance

Influence on lead time scheduling in MRP

Hello,

Hi,
During MRP run for single material by MD02 or on plant level by MDBT,
For MRP control parameters-
Scheduling take value as 2 - Lead time Scheduling and Capacity Planning.
and run the MRP.
With this you will get planned orders, and production rates are calculated as per time mentioned in routing.
But if you take scheduling value as 1 - Basic dates will be determined for planned order, then you system not consider lead time. Dates are picked from material master.

MRP - Problem in scheduling of MRP created schedule lines

Hi,
I am working with single level BOM of FG and trying to generate Schedule lines for RM as per requirement coming from FG - BOM explosion during MRP run -
Material master setting of RM is as below -
MRP type - PD,
Lot Size - Ex,
Procurement type - F,
Planned dlv time - 14 days
i am getting dependent requirement as below -
06.07.2009 - 2000 EA
13.07.2009 - 1500 EA
01.08.2008 - 1000 EA
And schedule lines are generated as below -
06.07.2009 - 2000 EA
13.07.2009 - 1500 EA
01.08.2008 - 1000 EA
The date of schedule line should be after taking calculation of planned del time of the RM, which is not happening. I can't understand why?
The planned dlv time is same in all 1) Material Master 2) Scheduling agreement and 3) Pur info record
Please help.
Regards,
Amol

Dear Amol,
the date shown is the ultimate reciet date and not start date.
Since you have already converted PR into schedule lines you will not be able to see the actual start date.
If it was still a PR you can see the release date as planed delivery time days early.
If the requirements date was say 31/05/2009 and you were taking planning run today then the recieved date would come as 05/06/2009.that is 14 days from today.
if requirement well beyond planned delivery time then the planned delivery time will not reflect in recipt date.

Scheduling agreement MRP run

Hi All,
We use Scheduling agreements for purchasing spare parts. The nightly MRP run checks the warehouse requirements and creates delivery schedule line to scheduling agreement.
Now the MRP run creates unnecessary delivery schedule lines to scheduling agreement if the earlier created delivery schedule line's delivery date has been changed manually.
Today the MRP run finds requirement for article XYZ and creates the delivery schedule line, where delivery date is 2.9.2008 (determined from articles basic data).
The Vendor confirms the delivery date as 3.10.2008 and the purchaser changes manually (transaction ME38) the delivery date to delivery schedule line accordingly and prints the created message.
The next MRP run creates new delivery schedule line, where delivery date is again 2.9.2008.
After that there are two open delivery schedule lines for article XYZ with delivery dates 3.10.2008 and 2.9.2008.
Why the MRP run does not notice the existing delivery schedule line with the new delivery date 3.10.2008?

Dates for Backwards scheduling when MRP Run

Hello experts,
When MRP run, which calendar does SAP take to schedule planned orders? where could I indicate it?
Thanks in advance.
Laura

Thank you all,
I have checked the calendar that is assigned to my plant, and, as you have said, is the one that is taking into consideration to determine the dates.
In my case, Saturdays and Sundays are not workdays. As a result, every purchase requisition has its release date assigned to a workday. What I have noticed is that although Saturdays and Sundays are not work days, planned delivery time and In-house production time is taking them into consideration to calculate the release date. What I mean is that those two fields are defined as calendar days. Is that correct??
Thanks again.

Scheduling after MRP

Hi All,
I've below case:
A Finished product A has a raw material R1 as a component.
Raw material R1 has planned delivery time as 2 days.
I enter the demand for A and run the MRP.
MRP gives scheduled planned orders for material A with some order dates and creates PRs for R1.
I've situation wherein planned delivery time for R1 is changed from 2 to 10 days.
(Or consider R1 not procured as scheduled)
Now, I re-run the MRP for A and expect that the order dates for planned orders are changed.
They are pushed further as planned delivery time for R1 is increased.
But dates remain same for planned orders of A. If we check PRs for R1, the dates are changed.
Strategy group for A is : 10
MRP run parameter for Scheduling : 1 and also 2 (both are used)
How the dates for planned orders for A are changed or even production order if not planned order?
Objective is that we should not get missing parts message in production order when it is taken
at order start date.
Thanks in advance.

Hi,
The dates in planned order will be captured from the inhouse production time in the material mater and in the routing time (if it is lead time scheduling).
After creation of planned order you can run the report MDVP to check the availability of raw materials for each planned orders. Once it is available you can firm it, then you can convert it to production orders where you will not get the missing parts.
You can also do availability check in each planned order (change view / MD12). The scheduling option is to generate the scheduling dates based on the routing times.
Thanks,
JK

Scheduling the MRP run

I have configured in the system for a Re-order point planning MRP run. But I have to execute the MRP run manually through MD03 transaction. Is it possible to schedule it ,eans system will execute MRP run automatically at a scheduled day of a month?
Please advice.
Thanks
Satya

hi,
I don't see any direct solution for it...
but indirectly,
Try to remove the line item ie. source from the source ...and try again...
its not possible to do via changing the dates...nor any source doc...system still create the procurment...
also try via changing the MRP indicator in the source list to NO MRP...
let me know updates..

Generate Delivery Schedules via MRP Planning run

The company wants to create Scheduling Agreements and generate the Delivery Schedules from the MRP Planning run - MRP 2 view via JIT.
Can you generate Delivery Schedules from Schedule Agreements if the company does not have an EDI server or APO set up?
Thanks,

Shirley Globe,
You seem to be putting the experts to the test.
As it was told you, you can generate schedule lines via MRP run. MRP run can be done (e.g.) trough MD01 /MD02 / MD03. Of course, you have to use the proper selection parameters to achieve your goal.

MRP is not generating any schedule line in my vendor's scheduling agreement

Hello all,
My question is: why the MRP is not generating any new line in my vendor's scheduling agreement?
This is the scenario:
I have created a vendor's scheduling agreement with transaction ME31L
I have created a customer's scheduling agreement with transaction VA31 and those characteristics:
- Forecast scheduling lines
- JIT scheduling lines
- MRP to DS type assigned to type C: Requirements according to forecast delivery/Deliveries according to JIT
I have run MRP with transaction MD01
MRP is generating some purchasing requistions, not purchase orders because we have set up a release strategy which requires 2 approvals, but those purchasing requests are not generating any new line in the vendor's scheduling agreement.
Any idea why it could be? Please do not hesitate to ask for further explanations. Thank you

Hi,
Check if stock is available for the material in that plant.
Also check the requirement date for the material and compare it with the planning horizon for that plant.
Check your material master MRP view.
Create source list(for material and plant in question) with MRP indicator 2.
Thanks and Regards,
Maheshwari

Schedule Line(Delivery Schedule) generation stopped

Dear Experts,
We are using Scheduling Agreeements to procure materials from Vendor.We are using MRP(type PD) to generate our requirements.We have noticed that ,for a Schedule Agreement- MRP generates Delivery Schedules accordingly,but if user will try to interven the process by entering a manual schedule line with some quantity,and Fix Indicator is getting fixed,after that MRP is not able to generate Schedule Lines,henceforth.
We had done the same things earlier,but MRP was able to generate Schedule Lines even after manual intervention by user.We have not maintained Fix indicator in Source List also and the particular material and the Agreement both have been marked as MRP relevant against that Vendor in Source List.
If we will remove the open delivery schedules having Fix indicator fixed ,after that we run MRP,then the Schedule Lines are getting generated,but for those Schedule Lines(Manual or thorough MRP) having Fixed Indicator fixed and have GRN transaction completed,we would not be able to delete those and also MRP will not be able to generate Delivery Schedules.Please advice what is the reason behind this and share the full concept of Fixed Indicator against the same?
Regards,
Soumick

It looks we encountered very similar problem,one item line in our Scheduling Agreeements can't be driven by MRP MD02/MD41,but if we add another same line item under this SA, this new line can be driven by MD02,and generated delivery schedule line.
I don't know why. Please give me some light! Thanks!

Donot want to fix the schedule lines at an Early date even P.O is the creat

Hi ,
If a material is sourced via a Scheduling Agreement, then MRP automatically creates schedule lines for this to meet MRP requirements.
However, if a separate PO is raised for the same material (irrespective of the supplier) at a date after one or more of the scheduling agreement schedule lines, MRP creates a message to reschedule in the PO in front of the schedule lines even if this is known to not be possible. the result is that the schedule lines for standard supply are not put in early enough.
And We don't want to fix the schedule lines in a t an early date to over come this.Is there any settings for the same.

Hello,
If you want to control MRP messages for rescheduling you can make settings in tcode : OMDW either at plant level or MRP group level.
You can introduce Tolerance value forward & Tolerance value for displacemt in No. of days here.
If system finds requiremnts within the tolerance no of days it will not create MRP Exception messages. This way you can avoid unwanted messages.
Thanks,
Ram
