Influence on lead time 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

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.

Lead time scheduling problem

Dear Gurus,
When I run MRP using lead time scheduling, scheduling is not taking place for planed orders, the start and finished dates are the same. I have already maintained the required formula for the processing time in the work centers of the operations.
What could be the reasons please suggest....
Thanks in advance!
Nilesh

Hi,
Please check your control key active for scheduling?
Then check your scheduling parameter in OPU5 and OPU3 should active for scheduling?

Need Automatic Lead-time scheduling in Planned Order using MD11

All,
Our users have a requirement that when they create a planned order using MD11, they would like system to do automatic lead-time scheduling based on the "basic finish date" entered by the user. Currently the system is taking 3 days from the in-house time maintained in material master to calculate the basic start date. But users want to use the 100 days that have been maintained in the routing.
Currently users have to click on "manual scheduling" on the planned order for system to pick up 100 days from routing which is an additional step for the users. Hence users want an automatic way in which system would do lead-time schedule when they enter the basic finish date.
Thanks,
Swapnil

Dear Swapnil,
In my understanding it is the standard SAP behaviour even if you have made the necessary settings in OPU5 for the planned
order type.
If my understanding is correct, then as per this setting the MRP behaves for the particular plant and order type combination.
Whenever you create a planned order manually you have to do a detailed scheduling and then you get the production dates
for the planned order.(This might be because generally when a planned order is converted into production order the system
carries out a lead time scheduling.- Check the same and correct me if I'm wrong)
Even if you update the material master through CA97,you will not get the detailed scheduling done along with the production
dates.So you have to perform this manual activity during MD11.
What is the reason of setting the in-house production time as 3 days,if the exact production time is going to be more?
Check and revert

MD04 dates not showing lead time scheduled dates

Hi experts,
In my MD04 screen, dates are not showing lead time scheduled dates (showing only basic dates scheduling) even after MRP run with lead time scheduling.
Please let me know if there is a way that the date column in MD04, shows the finish date from lead time scheduling.
thanks
Jay

Hello
Production dates are not displayed on MD04.
You can include additional fields on MD04 using a BAdI and you can use your own logic to add the production dates.
You will find the relevant BAdI on the following document:

Replenishment lead time & Scheduling Agreements - Please help

Hi,
I have a few questions & issues in regards to Replenishment lead time & Scheduling Agreements.
1.     Where are stock requirements & Replenishment lead times configured?
2.     What is a stock/requirements list?
3.     What is Replenishment lead time in MD02/MD04?
4.     Why do negative supply values appear under replenishment lead time in MD02/MD04?
5.     What are the differences between MD02 & MD04?
6.     How do you get to the following screen, since I canu2019t get here from MD02 or MD04 (missing buttons and Replenishment lead time information):
http://i34.tinypic.com/9hl9hz.jpg
Please help. This is very important.
Thanks,

Hi Laura,
The RLT can be set in the Masters Materials.MMR and Also in the Documnet Type Configuration.
But as per SAP standard Procedure the Prority will be the document type.
That means the RLT given in the Order document will overseed the RLT given in the MMR.
Go to material master and select MRP3 view. There see what is maintained for "Strategy group". Now go to OVZG, select this Requirement Class and tick the field "Rq" against this.
Now go to OVZH, select your Requirement Type and ensure that the above Requirement Class is assigned to your Requirement Type.
Now create a sale order and check in MD04.
Hope ethis helps u..

DIFFERENCES between BASIC SCHEDULING and LEAD-TIME SCHEDULING.

Hello SAP Gurus,
Kindly let me know the differences between BASIC SCHEDULING and LEAD-TIME SCHEDULING.
Looking for your early feedback.
Warm regards,
Kaushik.

Hi,
Basic scheduling :
1.Basic dates are calculated.
2.Exact to day.
3.No cap reqmts are generated.
4.uses the inhouse production time from material master.
5.carried out automatically during planning run.
In basic date calculation ( order start date/ order finish date ) the system always
calculates backward scheduling.
1. From the reqmts date the system subtracts the GR processing time to
calculate the order fininsh date.
2. From the order finish date the system subtracts the inhouse production time to calculate the order start date.
3. From the order start date the system subtracts the opening period given in scheduling margin key to calculate the order opening date.
Lead time scheduling :
1.Exact to second
2.ie production start date /time and finish date and time are calculated.
3. cap reqmts are generated.
4. uses times from routing.
5. carried out only if the scheduling mode in MD02 screen is kept with indicator 2.
From the order finish date the system subtracts the float after production to calculate the production finish date.
From the production finish date the individual operations in the routing are scheduled backwards to calculate production start date.
From the production start date the system subtracts the float before production
to calculate order start date.

Lead time scheduling Vs Takt time scheduling

Hi Experts, we are planning to implement sap in one of our plants..below is our business structure for your understanding..
OEM - Mini bus Manufacturer which is the customer
Bus seat manufacturer - Our plant (we already have sap here) - we already have sap repetitive here
bus seat components manufacture - our plant (we are planning implement sap here)
based on bus seat forecast the component plant will drive their production and will be send it to assembly plant which is seat manufacture.
I have two questions
1. what should we do in our component plant discrete orders or repetitive? I know you cannot tell me without seeing the plant but that my question. what questions should be ask our business to make this decision? how do anyone make the decision of going either repetitive or discrete? pleade do not point out the link to rep vs dis.. I have already those but I need something more in detail..
2. I was reading a lot of help.sap.com and I have a question on below statement
Basically, you can use two different types of scheduling:
Sequencing with takt-based/rate-based scheduling
The system schedules the planned orders using the number of takts and the takt times/rates of the line hierarchy. You define the line hierarchy in Line Design. In this type of scheduling, the system does not create any capacity requirements and only schedules the main lines. The system does not schedule the feeder lines.
Lead time scheduling
In lead time scheduling, the system creates capacity requirements and also schedules the feeder lines. The system uses the operations from the rate routing or the standard routing for lead time scheduling.
what does lead time schuling will also do feeder line scheduling and take based does not schedule feeder lines means? can some explain with an example?
Thx

any help is appreciated

Difference between r/3 planning( lead time scheduling) and APO planning

Hello APO Gurus,
Please let me know the difference between the R/3 capacity planning by using lead time scheduling and APO capacity planning for a work centre.
Both in both cases you can use the lead time from routing OPERATION.
Please let me know where the planning differs.

Is Oracle MRP efficient enough to reduce Inventory?Role of Lead time setups

Gurus,
I started understanding MRP these have the following questions,appreciate your inputs on below items
1)Does Item Lead time setups play a role in MRP?If Lead time setup is blank for all items,,does MRP work efficiently?
2)We just use MRP..not using any other inv rep. techniques like Min - Max etc.Our inventory is 3/4 times more than our monthsly revenues?exmaple our one month shipments are like 1 Mil.our inventory is like 4 Mil..Is it ok?how to reduce inventory?
3)how to improve our planning?
we are on 11i and discrete mfg.
thank you.

1)Does Item Lead time setups play a role in MRP?If Lead time setup is blank for all items,,does MRP work efficiently?
Lead times do play an important role in MRP. If lead times are blank, MRP will assume that all items can be procured / made in no time at all. The recommendations you get in MRP will be based on this incorrect assumption.
2)We just use MRP..not using any other inv rep. techniques like Min - Max etc.Our inventory is 3/4 times more than our monthsly revenues?exmaple our one month shipments are like 1 Mil.our inventory is like 4 Mil..Is it ok?how to reduce inventory?
Some companies have 52 inventory turns a year; some companies have 2. You are somewhere in between.There is no way for us to tell if you have too much inventory or too little. It highly depends on the industry you are in and on your business model. The best way is to compare yourself with other companies in the same market segment.
Inventory reduction is an art; not science. You can start looking at your excess and obsolete inventory and identifying patterns that lead to perceived excess. You can start looking at procurement practices. You can start analyzing MRP recommendations and acting upon them as required.
3)how to improve our planning?
You need to define what you mean by "improve". Oracle MRP is but a tool to improve planning. You need to implement a proper S&OP process to improve the planning component. You need to have a good review of your processes to "improve planning".
Sorry this is nebulous and may not help, but your question is quite generic.

ICal Week view, Date is not aligned with the Time(schedule) of each date

Well, just like it says over there (`` ). I've recently been to China for a business trip, and I suppose the different time zone may have had something to do with the problem. Now I'm back home, changed the time zone back to normal, still the iCal shows in the weekly view that the Date on the above is not aligning with the Time and schedule. Any suggetions would be grateful!!!

Hi,
i omit the scheduling maergin key in material master,
the result of MRP is
BASIC DATES
Finish 15.10.2009
Start 14.10.2009
PRODUCTION DATES
15.02.2010 14:33:25
14.10.2009 07:00:00
scheduling type i planned order is still "backwards"
so in MD04 it is say that the goods is available at 15.10.2009 same with requirement dates.
this seem not right.
it seems that order finish date is not adjusted by lead time scheduling on "today scheduling".
Is there a way so order finish date is adjusted by lead time scheduling on "today scheduling" ????
Best regards,

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
iam trying to run MRP at my client place
facing problem in planned order dates
i choosen tequirement type BSF and strategy group as 11
in md 61 pir was given in a month of june2008(monthly)
after mrp run at modo4 iam getting planned order with
execption message 64 called order date in past
means iam getting planned order START DATE AND END DATE IN THE MONTH OF JUNE
where as i need to my planned order satar date in MAY MONTH and
end date must be 1st of june
means i given PIR which is my start of my june month
checked scheduling parameters which says backword scheduling, and i choosed planning mode 3 and leddtime scheduling
plz suggest which setting effects the planned order start and end dates??
regards
sasikanth

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.

Manufacturing Lead time, milestone operation wise

Good Evening to All !
I have a scenario. I am explaining this scenario through 1 example.
We have a material 'X'. Inhouse production time for this material is 6 days, which is maintained in MRP2 view.
Now in Routing of this material 'X' there are total 10 operations starts from 1 to 10. Operation No. '4' & Operation No. '10' are milestone operation. The workcenter for both milestone operations are different. Now in house production time which I maintained in material master is total lead time for material 'X'.
The requirement is: Workcenter of Operation "4 "wants to know on daily basis that what quantity should be delivered from their workcenter.
Now my question is that can I maintain this lead time(6 days) in 2 parts as:
Till operation "4" my lead time is 5 days &
From operation "5" to Operation 10 lead time is 1 day.
Please suggest all possible solutions.
Can APO help in this scenario.
Thanks in Advance.

If you run MRP with "lead time scheduling" (instead of "basic dates"), it will schedule the order by the routing, and let you know the planned workload for each WC in advance.
