Compute manufacturing lead time
Pls tell the detailed computing lead time in oracel.
Thandks
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.

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.

WO scheduling based on lead times defined in item attribute
I wanted WIP to consider the fixed & variable lead times specified for the item - where I am not rolling up mfg lead times using BOM.
Has anyone been able to automatically schedule WO start date based on the lead times inputted in Item attribute.
nullDear Bimal,
The manufacturing lead times (setup and operation) are resource specific, and to declare them at item lead time attribute level is not practical (you need to define too many item levels in BOM to reflect every manufacturing step). The other work around is when routing is defined, you define two resource steps for each resource and make the first step lot basis and give setup time as usage rate and the second step item basis and operation time as usage rate. This gets reflected in manufacturing scheduling irrespective of quantity limitation (to define lead time at item level you need to define lot size also). I hope this takes care of your needs. -
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
ksrDear,
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,

Lead Time for Purchasing Material & Manufacturing Material
The query is related to the process of Material Requisition planning.
I need to know from where exactly the system picks up the lead time for generating Purchase requistions?
- For purchased material (lead time from placing order to actual recipt of material, time needed for QC checking till its release)
- For own manufactured material (lead time at each work center in the recipe along with actual time required for a particular process)Hi
for your information for any material the data for the lead time comes from the material master
http://help.sap.com/saphelp_46c/helpdata/en/fd/45b7ee9d6411d189b60000e829fbbd/frameset.htm
if you click on the link you can get the entire process.
as you can see SAP picks up the deatil from the MRP2 view of the material master.
hope this is helpful.

How to store lead-time and price per MPN for a single Item
We are probably one of the only CEM's that use Oracle Applications in a one-to-one MPN-IPN (Oracle Item Part Number) relationship. We do not currently store multiple Manufacturers under a single Item. Rather, we use the Customer Item Cross Reference to rank the customer's AML, with each IPN tied to a single MPN.
We are looking at moving into a one-to-many "world" in Oracle but are not sure how we can handle different pricing, lead-time, preference, status (prototype, production, obsolete, do not use), etc. for each Manufacturer's Part Number under a single Item. How are other CM's handling this???Hi Greg,
Unfortunately, DIAdem Datafinder doesn't really support much in the way
of Date/Time search outside of the File Level Creation Date property.
In order to make the creation time of the Channels searchable you would
want to create some custom properties (or use the existing RegisterInt1
- RegisterInt6) to define your own searchable properties.
For example, since you know that you have one TDM file per day, you can
start your search by find the desired day on the File Property Level,
searching the "Creation Date" property. When you store your TDM
properties, you could store the hour creation as an integer (and
thereby searchable) in one of the RegisterInt properties of the
channel, or create your own custom "Hour" channel. You could similarly
save the minute and second property in their own custom properties.
Then, since you're saving integer values, you can then search those
values to determine the time that the channel was created.
I realize that this isn't ideal or elegant, as in total it requires 4
searches (date, hour, minute, second). But that is the most
straightforward way of searching your channels by creation date/time.
Hope this helps Greg, let me know if you have any other questions.

Lead time reffering to open SO- - -***** URGENT ***
Hello
When we create a brand new PO, the materials due date should be automatically
calculated using the materials standard Lead Time. For example, if we are to create a PO on 10/1/07 for a part that has standard Lead Time 65 days, the materials due date shouldbe automatically calculated as 10/1/07 + 65 days = 12/5/07 and the PO shouldshow that the part's statistical due date and delivery date is 12/5/07.However, recently SAP has been checking a pending sales order's furthest duedate and stretch the PO's due date to match the sales order's due date. Forexample, in the previous example the PO's due date should be 12/5/07 but if there is a sales order that is not due till 3/7/08, SAP calculates that the part
on this PO is not due till 3/6/08. This new function is affecting our PO
creation and its due date. Could you advice so that POs automatically use a
part's standard LT to calculate the part's due date instead of using SO's due
date?

I had read that Lead time for Purchased items is calculated per 7 working days / week, by default. However, when I checked this, I found that the MRP planned orders were always considering our mfg calendar that has 5 working days / week.
Anyone tried this.Industries & Product which have stabilsed have the same measuring yard and standards. This is also applicable for calendar working days, otherwise we need to device the 'interface' because the results would be weird, specifically when we speak of 'supply chain'.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by erik anthonsen ([email protected]):

Dear friends,
Is there any report in SAP LE which can give the total lead time for delivery of materials from the plants to the destinations(customer)
Your valuable reply is highly appreciated.
Regards,
SampathSampath,
I am not aware of such a report.
The duration of time scheduled in a Sales order between the shipping point and the destination is carried in the Sales routes (configuration transaction OVTC). The routes that your company uses can be determined in a number of ways. Information (including duration) can be seen in Table TVRO. Information concerning determination (which route is associated with a source-destination pair) are usually contained in table TROLZ. This configuration is in IMG>SD>Basic Functions>Routes>Route Determination>Maintain Route Determination.
If you actually interested in the 'lead time', which also includes manufacturing/procurement time, Pick/Pack Processing time, etc, this is a bigger task. More data needs to collected.
In either case, I believe you will have to commission your ABAPers to create a Z report.

How to influence lead time from vendors
Hi All,
I am trying to figure out how I can consider the impact of the Chinese New Year on the lead times of finished goods manufactured in China and sent to plants in the USA. I set up a special data range to account for this in the Calendar which was then assigned to the Time Stream ID.
My initial thought was to assign the Time Stream ID to the Shipping Calendar at the Vendor location (location master) but this does not seem to have made an impact on the lead time. I also tried using the Production Calendar, but this was also without success.
Does any have any recommendations that would assist me here.
Kind Regards,
PaulHi Paul,
If you are using APO PPDS means production planning heuristics from PPDS Scheduling will be done based on Planned delivery time in external procurement relationship. Planned deliver time will be considered based on production calender mentioned at vendor location.
You may be facing problem because transfer to R/3/ ECC will consider planned delivery time in calender days. Check your setting in CIF that you are not retransfering planning results from ECC back to APO.
For more information go through below link

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,
cookieDear 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

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. -
Lead time and Route time estimation used for deliveries
Dear Friends,
Can anybadyu let us know how to estimate lead time and route times for deliveries, and what is the exact meaning of the these two with differences
if possible can you please give me the configuration steps, as i know at this movement route times are maintained in the route and lead times are maintained in the material master MRP view.
what was these field impacts in the delivery..
requesting your view as soon as possible
Thanks
raju.Hi there,
Lead time is the time in which the material will be available. It is called Replenishment lead time RLT. It is maintained in MRP view of material master. RLT can either be inhouse processing time for inhouse manufactured goods or order time + goods receipt processing time for externally procured goods.
Whereas time mentioned in route is used to calculate transit time during delivery scheduling. That is the time taken for the goods to reach customer from shipping point.
Both the times are imp for delivery scheduling.
When the customer places an order, if the material is not available, then the system will take end of RLT as material availability date. From that date, it will carry forward scheduling & propose a new confirmed delivery date.

Sivanand
