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.

Difference between Req with insufficient lead time and lead time const

Hi ,
1) Can anyone explain the difference between Requirement with insufficient lead time and Requirement lead time constraint exception messages. Both seems to be similar for me with the compressed time.Also at what situations these exceptions are generated.
2) what is minimum lead time required ,actual lead time and its calculation.
Thanks...

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
Roland Böhm

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.

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.

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

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..

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

How to measure time difference between zero crossing of a sine wave and rise time of a pulse on a same graph?

I have a 50Hz sine wave and a pulse signal on a same graph. The phase difference between two is between 0-90 degrees.
Now I need to calculate the time difference between (when the sine wave crosses zero volts) and (when the pulse rises). The frequency will stay approximately same for both signals.
The application is for a three phase generator. In simple words, when the time difference between the zero-crossing of sine wave and the pulse rises increases, that means that the load on the generator has increases.
I am a beginner user of LabView (version 9, 2009), maybe it is a very simple problem but I've been pulling my hair out for the last few days and coudln't figure anything out. Any help would be greatly appreciated. I am using DAQ USB-6008 to measure these voltages and pulse from the generator and a sensor
I have attached a jpg (a graph that i just made with excel to explain). The time 't' is what I am trying to measure
Cheers

Solved!
Go to Solution.

Hi
Thanks for the code but I'm afraid it won't work. Like you said the probability of choosing a value that is on both graphs may not happen. This is something that I would like the code to do automatically.
But I did use the previous code posted and made some modifications to it and it seems to work perfectly. Now the next thing is to be able to get just that one value that tells you the first time difference.
Here is what I get using that code.
As you can see from the t Values. I only need the one that is highlighted. If there is a way to filter out the rest it would be great.
I was thinking of a while loop and as soon as the value is higher than 3E-5 it would store the number and stop the loop, but I'm not too familiar with arrays in labview.
Here is the the code modified.
As you can see, it wasn't that big of a modification and it still is your code.
I will keep trying.
Thanks for the help

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!

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

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:

Differences between Oracle 8i for a UNIX Platform and Oracle 8i for a Linux Platform

Hello,
J would like to know if there are some differences between Oracle 8i for a UNIX Platform and Oracle 8i for a Linux Platform.
I know that there are some differences on Oracle 8i Parallel Server and i know that some products are not include like precompiler (Mod*Ada, Pro*FORTRAN) on a Linux Platform.
Thank you.

We have installed Oracle 8i on Solaris 8 and it had a great performance, of course that the hardware and licence invested here was costed my the office where i work. Personaly i'd installed linux reh hat 8 and oracle 8i, imagine that, it could be implemented by any individual that has the time to do so.
By buyinng from a company that has a good background you could be sure that you will have support.
Bottom line, if you have the $ to buy great hardware go for a unix platform. But if you don't a Red Hat Linux Server Licence with a 1 year sopport and Oracle data base is about 3500Dls.

DIfference Between User Exits, Screen Exits, Menu Exits And BADI

Could any one let me know the exact/practical dIfference Between User Exits, Screen Exits, Menu Exits And BADI. ? And why BADIs are more proned to use?

Hi,
User Exits:
A user exit is a three character code that instructs the system to access a program during system processing.
SXX: S is for standard exits that are delivered by SAP. XX represents the 2-digit exit number.
UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number
Menu Exits:
Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Screen Exits:
Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screens flow logic.
BADIs:
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
And why BADIs are more proned to use?
In contrast to above customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example).
All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard. A single Business Add-In contains all of the interfaces necessary to implement a specific task.
The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects.
