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
tuff

Since 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).

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.

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..

Total replenish lead time

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,
cookie

Dear Cookie
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

Replenishment Lead Time

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.

Hello,
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,

Target and Actual Lead time in MCP1 report

Dear Experts,
In MCP1 report, what is Target Lead Time and Actual Lead Time. How it is calculated?
Thanks in advance for your valuable replies.
Regards,
Jejesh

Hi,
                                                                                Target lead time
On the operation level, it is the time period between the scheduled
    input date at the work center (target input) and the latest scheduled
    finish of the operation.
The target input date is calculated through the scheduled execution
    finish of the previous operation.
On the order level it is the time period between the scheduled start and
    the scheduled finish.
and
                                                                                Actual lead time
At operation level, the time between the input date at the work center
     and the completion confirmation date (the total from queue time,
     execution time and move time).
When calculating, the input date is determined via the completion
     confirmation date of the preceding operation. The process-dependent
     wait time of the preceeding operation is subtracted.
At order level, the time between the reported start date and the finish
     date (the total from execution times and transit times of the operations
     as well as the order floats before and after production).

Rajesh

Total replenishment lead time calcuation

Experts,
how does SAP determine the replenishment lead time for a part under the following circumstances,
- purchase part (ProcType F)
- two PIR for two vendors with diffrent delivery times per vendor.
- Source list has no fixed vendor
- quote arragement in place.
in MD04 I see the correct split acc. to quote arrangement, but currently I have the effect that the replenishment lead time for this part changes form delivery time of vendor A to delivery time of vendor B from time to time. Unfortunatly I can not see a pattern in behind.
Who can explain this behaviour ?
Thanks in advance
Jörg

Hi,
- purchase part (ProcType F)
Depending on the setup done in OPPQ (push button - external procurement), the lead times will be read from Info record first if not existing then from material master or directly from material master.
- two PIR for two vendors with diffrent delivery times per vendor.
If the vendor is fixed, then the lead time from the fixed vendor is selected. If quota based, then from the vendor to whom the quota is allocated to.
- Source list has no fixed vendor
lead time from mtl master.
- quote arragement in place.
Lead time as per info rec of vendor selected based on the quota arrangement.
Now all the above is theory... so take some examples in your sandbox & do some testing to see it n revert if you face any issues.
Regards,
Vivek

Availablity Check in Sales Order with Total Replenishment Lead Time

Dear PP Consultants,
This is regarding the TRLT field functionality during availablity check of Sales Order.
I understand the TRLT field is defined manually in Material Master MRP-3 view as the sum of the longest lead time of raw material, in-house-production time and floats.
If during the availablity check of Sales Order, the raw material which is having the longest lead time is already available in stock, can the system calculate the TRLT dynamically and propose the delivery date in sales order only based on in-house production time??
Is there any setting that can be made so that during availability check of Sales Order, the system considers the stock of raw materials and then propose the confirmed dates?
Your early respose is much appreciated. Thanks a lot in advance for your valauble suggestions.
Thanks,
Kishore

Hi,
The RLT is not dynamic, and is not related to the stock situation of the components.
It's only purpose is to give an estimated availability date for the finished material (sold) when no better information is present (like a procurement element).
The only way I know to get an availability date taking into account the availability of components, is the assemble-to-order scenario. In this scenario (MTO!), a production order is created automatically during the creation of the sales order. The system can then use the production order features like scheduling and availability check of components to propose the availability date for the finished product.
Besides that, you can get much more complex solutions for ATP using APO's ATP engine.

Mario

ASCP Yield and Resource Lead Times

Hi,
I am working on Advanced supply Chain Planning on R12. Both ERP Source and Planning are on different instances. We are also using Oracle Shop Floor Management. In the Network Routings we have included a lead time resources at step 10, 20, 30. The resources are as follows:
These resources are defined as 'Machine'
Resource for operation 10: ASSY-LT, 112 hours, Schedule 'yes'
Resource for operation 20: TEST-LT, 64 hours, Schedule 'yes'
Resource for operation 30: PACK-LT, 48 hours, Schedule 'yes'
We also have only one shift with 8 hours. The resources are not available for 24 hours.
We also have yield at each of the above operations.
Lead time rollup calculates 28 days for the item correctly.
We are encountering a problem with ASCP Plan. The start dates and yield calculations using constrained plan with Enforce Demand Due Dates constraint seems problematic. If we check 'Calculate Resource Requiremnents' option, the plan calculates yield but the lead time gets reduecd by one third and start and completion dates for a planned order (and ATP etc.) are not accurate.
If we uncheck 'Calculate Resource Requiremnents'option in the plan, lead times are accurate but plan does not calculate yield.
We are not sure what is causing the problem.
Does anybody know what options or profiles control this behaviour?
Your help is highly appreciated.
Thanks.
Vijay

Hi Vijay,
important for your lead time calculation is the setup of the calendar and shifts and what shifts are assigned to the resource.
You say you do not have enabled the 'Available 24h' option. We are also using leadtime resources in certain cases, for example LT for Assembly. But in these cases we enable the 24H option. Next to this we set the Resource capacity to 'unlimited' by setting units to a very high number (1000 etc.) on resource level, to prevent that the system gets into capacity conflicts here.
And the yield calculation indeed should be quite independent of the leadtime resource.
best regards,
David.

Check without RLT (Replenishment Lead Time) not working as expected

Dear All.
We're seeing a sales order ATP situation for externally procured materials, in wihch RLT is not checked. Or at least we've flagged the checkbox in atp config to not include RLT.
However, RLT is still picking up the planned delivery time and GR time.
And if I blank out the GR time and planned delivery timie, then it just confirms it.
It acts like RLT is still being used in the check even though RLT is turned off in the availability control (OVZ9)?
Ideas? Anyone see something like this? Does it only work on internally procured materials?
Many Thanks!!!

RLT is turned off in the availability control (OVZ9]
Make sure, the box is checked in OVZ9 to avoid RLT in the availability check. You can do more analysis, by highlighting the sales order line item, then clicking the display availability button. In the next screen click on scope of check button, which shows the OVZ9 details.
Did you check other parameters like Route, pick/pack time?
Regards,

Replenish Lead time effecting Materials

We have issue in Sales orders, For some materials confirmed qty is getting 0. Availability check codes and material determination are maintained correctly .
It happens once a week, then user have to edit order manually. Its happening for different materials at a point of time(Ex: Item 1002876 unable to get confirmed qty, after some time we test creating order with same material and there is no same issue)
Can any one faced this kind of situation before, please share thoughts on same. Does RLT enhancements effect orders?

Hi Guys
Thanks for looking into it.
Yes the material i have listed above is a BOM that has 6 products under it with item category: L (stock item). The BOM products have item category as NORM and 4 products are material type: HAWA (trading goods) the rest two are FERT: finished

Splitting Replenishment Generated PO by Delivery Lead Time

Dear Folks,
When I run replenishment, I would like the auto generated PO to be created based on the replenishment lead time/planned delivery date.
Is that possible?
For example, I have 2 SKU, one with planned delivery time of 2 days and 1 with planned delivery time of 1 day by the same vendor for same plant.
When I do a replenishment run, I would like to have 2 PO created.
Best Regards
JW

Dear folks,
It could be that my original question was not very clear.
In each PO line items, there is this field 'Delivery Date', this date is usually derived from the Planned Delivery Time from the material/article master. I am using SAP retail.
Basically, what I would like to achieve when I run auto-replenishment is:
- different PO created with each PO containing on the items with the same 'delivery date'.
- if an item has a different delivery date from the rest, a separate PO will be created.
Assume that the requirements/demands are already triggered - reorder point etc.
Any advice would be appreciated. Thank you.
Best Regards
JW

Lead Time for manufacturing and its corresponding Quantity in Material Mast

Hi all ,
Do we have any feilds in SAP Material Master
which are useful for
1) Lead Time for manufacturing
2) Manfactured Lead Time Quantity
if the mateials are produced inhouse.
thanks
ksr

Dear,
There are no such a fields in material master, But in MRP 3 view you will get theotal replenishment lead time field.
Which use for the produced in-house if the replenishment lead time is included in the availability check:
This is nothing but the in-house production time and, if available, the goods receipt processing time.
Also refer this link to calculate the in-house production time correctly,
Total Manufacturing time for assembly
