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,
Laura
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..
Cheerzz..

Reg: lot size and replenishment lead time
1. please explain about lot size and replenishment lead time.
2. please also explain about consumption based planing and in steps explain how to perform manual and automatic reorder point(transc code please)You use the lot-sizing procedure to determine how the system is to calculate the reorder quantity in the planning run.
A lot size defining the lot-sizing procedure is assigned to every material master record applicable to materials planning.
The lot size is defined in Customizing by the combination of the lot-sizing procedure and the lot-sizing indicator.
Three procedures for lot sizing are available:
o static lot-sizing procedures
o period lot-sizing procedures
o optimizing lot-sizing procedures
You use the lot-size indicator to define the procedure.
The following parameters are also available for controlling the lot-sizing procedure:
o Short-term and long-term lot size
You can split the lot-sizing procedure into a short-term and a long-term period. This means that you can select one lot-sizing procedure in the near future and a different one in the distant future.
You define the periods in the section of the screen entitled "End of the short-term period/start of the long-term period".
The valid from date of the long-term lot size area is defined via:
- a periodicity
- a number of periods
The beginning of the long-term period is calculated by taking today's date and adding the number of periods in the future; the long-term planning period then starts on the next complete period.
Note
For materials that are planned using the short and long-term lot size,
it is recommended that you define a maximum MRP period. Defining the
MRP period has the effect that materials after a certain period are
included in planning even if no changes relevant to the planning run
have occurred. This avoids a situation where order proposals created
with the long-term lot size move into the short-term period because no
changes relevant to MRP have occurred for the material.
You define the maximum MRP period in the step, "Define maximum MRP
period". A material that is planned on a regular basis should also be
provided with an MRP type that contains the indicator for regular MRP.
o Scheduling indicator
For period lot sizes, you can use the indicator for scheduling to
determine whether the availability date;
o is to be set to the first requirements date in the period
o or is to be set to the beginning of the period
o is to be set to the end of the period
o or whether the period start represents the beginning of the planned
order and the period end represents the availability date (repetitive
manufacturing)
Interpretation of the delivery times
For the lot-sizing procedure, you can also define whether the period
start is to be interpreted as the delivery date or as the availability
date using the indicator, "interpretation of the calendar times".
NOTE
The indicators, Scheduling and Interpr.deliv.times are mutually
exclusive.
Indicator for the splitting quota
For the quota arrangements, you can determine whether the requirements
quantities are to be distributed to several items, that is, whether
they are to be split. With the splitting quota arrangement,
requirement quantities are not simply allocated to the smallest quota
rating. Instead, they are distributed among various sources using the
following formula:
Quantity for source of supply X = Quota of source X * reqmts quantity
Sum of all quotas
Overlapping indicator
The overlapping indicator along with the cycle time in the material
master record are used to split the planned orders into several
partial quantities whereby the in-house production time overlaps by
the cycle time.
Lot-sizing procedure for make-to-order production
In make-to-order production, you can use the indicator, Lot size for
make-to-order production to determine whether,
the order quantity is to be calculated using the exact lot size
the order quantity is to be calculated using the exact lot size and
the system is also to take the rounding quantity or the minimum and
maximum lot size into account
the order quantity is to be calculated using the lot-sizing procedure
defined for the short-term area
Maximum stock level variant
The system only displays the Maximum stock level variant field in the
lot-sizing procedure, Replenishing to maximum stock level. The
indicator only has an effect in connection with reorder point planning
taking external requirements into account and in connection with
material requirements planning and controls how the system calculates
lot sizes. -
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
JayHello
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:

Batch and replenishment lead time
Hi,
I read the following statement in SAP help portal and am confused.
Please help explain with an example.
The replenishment lead time should not be considered in the dynamic availability check for batches, since batches are not reproducible
Question: Why not? basically not understand above statement.
thanks
tuffSince a batch is created on a given date at a given time, and it has specific charactreristics and values, you cannot make anymore of that particular batch. The only available qty of a specific batch is what you have available in actual inventory. Therefor no replenishment lead time is to be considered because you can't replenish a batch.
You can use replenishment lead time in say ATP because that will tell you how long it takes to make a batch of material that meets the general spec of the material.
When a material is not batch managed you can use replenishment lead time in the availability check if you want since you can make more material to meet the customers requirement, (i.e. the general material spec).

Difference Between Basic Date Scheduling and Lead Time Scheduling.
Dear FRndz,
Kindly help me out the difference between the Basic Date Scheduling and Lead Time Scheduling.
Regards,
SRiniDear,
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.

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.
Regards,
Ravindra DeokuleCheck out
http://help.sap.com/saphelp_scm50/helpdata/en/99/ed3a981d0f11d5b3fc0050dadf0791/content.htm
particularly the section "Which functions of the operations relevant to scheduling are supported?"
It will give you a flavour of what can lead to difference in planning. -
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!
NileshHi,
Please check your control key active for scheduling?
Then check your scheduling parameter in OPU5 and OPU3 should active for scheduling?

I am going through TSCM60 and am facing a problem understanding the concept of Replenishment Lead time. I will explain what problem I am facing grasping the concept.
As can be seen, Replenishment lead time according to the manual:
Only the inward and outward movements that take place within the replenishment lead time are included in this check.
Now this seems in contradiction to checking the box: Include Sales requirements because this considers the requirement from the already made sales orders. On the other hand the RLT only the time till the product (from inhouse production or external procurement) becomes available.
For example,
For an already confirmed Sales Order requires a Material Availability Date of 7 October for a delivery on 10 October. Now, an order comes along later that requires a delivery on 8th October and hence a MAD of 5th October. The problem is that if using the RLT, the required MAD is to be provided to the system for the latter Sales Order (5th Oct. MAD), the full amount of the material is not available on 7th October for the former Sales Order.
So what is the system going to do if both RLT and Include Sales requirements are being employed?
The graph in the manual makes it look as if the system is going to commit the full amount for the 5th October MAD and snub the customer requiring the delivery on 10th by sending him/her the remaining material i.e. a partial delivery on requested date of delivery.
Edited by: shabie on Sep 26, 2011 7:52 AMHello,
Thank you for the appreciaton.
Yes. Your understanding is correct - that it is generally advisable to not activate it but it can be activated for in-house production and materials that are easily available.
For your question regarding points:
For it's use in real life - You just appreciated me & that is the genuine example of use of points in real life. It is more about feeling of satisfaction - to give back something to the forum from which I have got so much. I remember of so many instances in past when client was bombbarding me with issues & I did not had ready solutions. SDN Forums & it's memers have always helped me during those times.
I don't know whether I am selfless or not... but one thing I can say for sure, contributing to SDN forums has help me a lot in learning SAP SD. Also there are many other senior contributors in the forum who are really selfless since last couple of years...
Thanks again,

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
Swathiany help is appreciated

Lead time scheduling- schedule result
hi all
in lead time scheduling, i go to CA02/3, then choose the "schedule",select "forward schedule" and put the base qty and the start date, the machine setup time display after runt he schedule is NOT same as when click the "schedule result ". it show 2.33 days...but my calculation is 2.03 days...
Anyone encounter same problem ?solved

Hi gurus,
anyone can explain why this field (total replenish lead time) is designed to enter manually instead of system automatically calculate from BOM for a manufactured part? and how does it work according to the following scenario:
product X is produced in plant=1000 from material A and B (both A and B are procured externally for plant 1000, to simplify the case)
in plant 1000, PO processing time=1day
A: planned del.time=3 days, GR. processing time=1 day.
B: planned del.time=5 days, GR. processing time=1 day.
to make X need 2 operation: 1st operation need 1 day to assemble A and B together, after assembling, 2nd operation need 1 day to paint, 1 day to dry
what's the total replenish lead time we should enter for X?
thanks,

3.if it's only for availability check, does that mean the MRP would not be affected by this field, then what would be the lead time feed into MRP? what's the relationship between MRP and availability check? why they use 2 different sets of data?
1) MRP will not take this field into Account for Calculating Dates
2) MRP for in-house materials - in-house production time & GR Procesing time ( Lead time )
3 ) For external Procured materials - PR processing time , Planned delevery time & GR Processing time
4) MRP Net Req. Calculation Concept is different from Availbility check Concept

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,
SwapnilDear 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
Regards
