Lead time calculation

Dear Gurus,
I want to calculate lead time between purchase order and goods receipt.how to do that???
Am having some doubts.
Does the lead time links with
Planned Delivery Time
Goods Receipt Processing Time
Purchasing Processing Time in material master. plz explain???

Hi,
If you create PR for a material, using MRP, then the planned delivery time would be picked up from the material master, please note that there is no source maintained yet in the PIR, so obviously that rules out planned delivery time of PIR and Vendor Master( even when u convert this P.R to P.O the planned delivery time will not change and will not be taken from the PIR)
Now if you directly create a P.O then the planned delivery time of the PIR is picked up , please note this difference.
I would recommend that you change the planned delivery time in the material, mnake it different from the planned delivery time of the PIR, and then run MRP, You will see that the planned delivery time in the PR would be based on the material planned delivery time.
Even if you assign source and convert this P.O using ME59 the PDT will not change.
Then you can try and create a P.O directly with the vendor, here you will notice that the PDT flows from the info record.
Please let me know if this addresses your concern.
Regarding your soure list issue, either you can remove the source list mandatory tick in MM or add the vendor whose PIR you are using into ME01, and it will definitely work.

Shailesh

Wrong lead times calculated between activities

Hi expert,
Client has following activity flow: 1 - 1A - 1B - 2. Relationship lead times: 1- 1a: 5day, 1a- 1b: 5day, 1b- 2a: 0day, 1- 2a: 1day.
We have maintained relantionships as necessary. But lead times from activity 1 to activity 2 is still not calculated as 1 day. Lead time for actitivity 2 calculated after activity 1B.
Please advise on solution.

Lead Time calculation in process order

Hi,
I have a process order to be created of 112.6 L. i have only one phase & one resource allocated. i have maintained my OH time as 1 H in my master recipe. now for resource i have maintained scheduling formula as ZRUNA = OH.
After creating Process order the system calculates phase timing as 1:17:44. Can anyone pls let me know how did system calculate 17 min & 44 sec extra.
Thanks & Regards,
Rohan Somji

Dear Rohan,
1.Check the length of break timings defined in the resource that is assigned in the phase.
2.Check in OPUZ whether for the process order type and plant combination whether scheduling is to include the break time also
(whether the check box for scheduling with breaks) is included.
Check and revert back.

Lead Time in Item Master

Hi
Does Lead Time in Item Master respect weekends and only count working days?
Meaning, for two weeks do I enter 10 or 14?
Thanks
Franz

Hi Franz
As far as I know, NO. You only have the option to include holidays in the MRP wizard itself which will then calculate against lead times. Best would be to test on a test database with both scenarios (with 10 or 14, and tick/untick holidays in MRP) and see what the results are.
According to the Online Help the above is correct:
Consider Holiday Table for Production Planning Factors in holidays and weekends in lead time calculation, as defined in the Holiday Details window. Holidays and weekends increase the lead time interval for MRP calculations.
Consider Holiday Table for Purchase Planning Factors in holidays and weekends in lead time calculations, as defined in the Holiday Details window. Holidays and weekends increase the lead time interval for MRP calculations.

Lead time in LSP determination

Dear all,
in subcontracting, there is obviously some time constraint: I have to submit a freight order to the carrier at least x days/hours before planned loading date. As far as I can see, there is no such field in the carrier profile (where it could be associated with transportation lane or at least starting location). Another logical point would be the freight agreement (I agreed with the LSP that he can handle all freight I submit to him x days/hours before planned loading date), but nothing there as well. The only way I see to model this is via incompatibilities (do not assign a freight order to a specific carrier if the loading date is less than x days/hours ahead of actual date), but this seems not very convenient to me.
Any other ideas?

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.

How is lead time in working days calculated in 2LIS_05_QVUDN

I was wondering if someone knows how lead time is being caclulated for 2LIS_05_QVUDN. I've found the tables associated and the function module but I can't find the actual calculation
Thanks

Hello
The lead time in working days works like this
If you have 1 inspection lot for a material   -the time from Lot creation to Usage decision given is the lead time.
                                                          Lot created               Usage Decision made       Lead Time
for eg Material X , inspection lot no   14/05/2008 10: 00          14/05/2008 14: 00            4 Hours
it converts the hours in to days . =4/24= 0.16 days
For total lead time individual lot's lead time sum is calculated
Hope this clarifies your doubt

Calculating Lead time.... Help......

We have two field in qals
QALS: Lot created     (ENSTEHDAT)
            Time                (ENTSTEZEIT)
Similarly we have two field in QAVE
QAVE: UD Code Date
            Time            (VEZEITERF)
I need to calculate the lead time
i.e.
Lead time = (Lot Created date & time - Date of UD & Time - Holidays as per factory calendar) / 24:00:00 hrs.
How to proceed????

hi Uttamagarwal,
Please check the below sample Code. You need to do declare the Appropriate Variable and ITAB.
"as NSTomar said , First use the FM to get the Date and Time difference
call function 'SD_DATETIME_DIFFERENCE'

Different Lead times for supplier in MRP calculation

Dear All,
We have different suppliers for a material. Different suppliers have different lead times and Min.lot size. Our requirement is when we run MRP system should suggest Pld.Order quantity for the supplier and also take lead time accordingly. I have done splits for suppliers by using Quata arrangement but system is only taking planned delivery time from material master record.
I also defined info records for the vendor and define lead time but still system is taking Pld delivery time from materials master.
Please help
Majid Ali khan.

Hi,
Go to OPPQ, enter your plant then click on External Procurement, there tick the check box Scheduling: Info Rec / Agreement.
This will ensure that the PDT is read from info-record if it exists.
Hope it clarifies.

Lead time values are not appearing in the report for current year.

Hi friends,
Iam checking a report in production. where lead time values are displayed as 0 for 1 key figure lead time3 (w/0 dim) . i found there is a formula for this it shows like NODIM ( 'Lead Time 3' ).and there is a value for cal.lead time
how can i get values in the report.
Thanks ,
VRV.

Hi,
Although your question is not clear, I understood that the formula built on that KF is NODIM. Basically it means, units of measurement is not considered when calculating.
Eg: 5 Minutes + 5 Kilograms = 10
You please try to analyze your KF by the above logic. Then you would be able to figure out why the data is not appearing in the report..
Assign if helps...

Sales order is not taking shipping transit lead time into consideration

Hi,
We have following scenario -
1. Sales order is created in AT organization.
2. There is no onhand in any of the organizations including AT.
3. The scheduled ship date for sales order comes as order creation date + item lead time = 15-Sep-2011.
3. PO for sufficient quantity is available at UK org with need-by date as 01-Jun-2011.
5. Post processing item lead time for this item is 1 day.
4. intransit shipment is setup between UK and AT.
5. Shipment Transit lead times are also set up at 3 days between locations of UK and AT.
6. ASCP plan is run.
7. Sales Order is unscheduled and rescheduled via API MSC_ATP_PUB, which takes the ATP details from UK (based on the sourcing rules). The sheduled ship date comes as 02-Jun-2011 (PO need-by date + 1 day of post processing).
8. Expectation is that API should also take transit lead time into consideration while calculating the ATP dates and hence the Expectation is that scheduled ship date should come as 05-Jun-2011 (PO need-by date + Transit lead time + 1 day of post processing).
Please let me know
a. if this is standard functionality of oracle or not.
b. if this is standard functionality then what setups are missing required for the same to be achieved.
UAT is held up for this issue. Please help urgently.
Regards.

Oracle is supposed to take the in-transit time into consideration.
Are you running a constrained plan or an unconstrained one?
Make sure you defined the inter-org network as described in http://download.oracle.com/docs/cd/A60725_05/html/comnls/us/inv/shipne01.htm.
or go to Inventory > Setup > Organization > Inter-Location Transit Times and enter it there.

Lead time only optional

Hello,
would like to setup lead time comming from catalog only as optional without check.
Now system is transfering lead time during creation of shopping cart. If the approval is not performed on the same day when shopping cart is created, system is issuing error message that delivery time is less that lead time.
Any hint?
TIA
GOrdan

Hi,
What is your SRM version? I think the delivery date is re-calculated based on lead time.
For example, Lead Time 3 days.
SC create. 2008-03-20 -> Delivery date is set 2008-03-23
Manager Approval 2008-03-22 -> PO delivery date will be 2008-03-25
You may change the mesage to warning. Please check the Message Control customizing.
You can also clear the lead time by BADI BBP_CATALOG_TRANSFER.

Masa

Lead Time recalculation/update

Hi,
The requirement in my project is the following:
I have a lead time for one material of 10 days. After two months I have recieved 2 PO's, one with 14 days and other with 12 days. The new lead time should be 13 days.
There is any way to calculate this and update the material master?
Thanks in advance,
Guiza

Guilherme,
WPDTC is the TCode that you run to calculate the planned delivery time. This transaction is available as of version 4.7. Currently we are upgrading from 4.7 to ECC 6.0 and it still exists in 6.0. There is a good description at this link in the SAP Help Library.
[http://help.sap.com/saphelp_47x200/helpdata/EN/f3/41b53c4d36265ce10000000a114084/frameset.htm|http://help.sap.com/saphelp_47x200/helpdata/EN/f3/41b53c4d36265ce10000000a114084/frameset.htm]
This program gives you a report of what the planned delivery times are in the info record, material master, vendor, and the calculated PDT based on documents and actual deliveries in the system. You select the items you wish to change and click the Change Planned Delivery Time button. You get a pop-up to verify you want to change the values. Basically, this is a mass change tool for planned delivery time similar to physical inventory transaction MIBC - Set Cycle-Counting Indicator that calculates and changes the material master indicators.
Hope this helps,
Paul
