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.

Difference between DB CPU and DB Time

Hi,
What is the difference between DB CPU and DB TIME in AWR report?
Br,
Raj

Hi,
Thanks for your valuable reply.
1,DB CPU is time spent on CPU. It means only ACTIVELY working on CPU. WAIT TIME is not includeed.
In 10 Minute interval with four CPU, Is the Maximum DB CPU 40 Minutes?
2,I read the below document about DB time. http://www.perfvision.com/docs/JB_AAS.pdf
I unable to understand at page 6.
It says that DB Time = Includes CPU Time + IO Time + Wait Time
I understand about Wait time.
CPU also involved to do I/O Time? Is it RIGHT?.Hence, Why did seperate CPU Time and I/O time in the document?What is the purpose of it?
Is it possbile to further divided the CPU TIME ? Like parse etc.....Which view provide it?
3,If you had four sessions actively working or actively waiting 100% of the time in that 10 minute period, then your DB time would be 40 minutes.
In a given interval,Where can i find NON Idle wait time in AWR?
Plese help me out it

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.

Stock transfer between storage locations and lead time

Hello,
We use stock transfer orders between different storage locations. Is it possible to maintain the transport lead time between storage locations somewhere or do in need to use routes and scheduling?

Difference between Basic Component and Standard Component

Hi Iam just learning JSF, at the same time I try to learn to use Sun Java Studio Creator at the same time. May I know what is the difference between the Basic component and the Standard component in the IDE.
I have been using the Grid Panel, each time I need a header I manually t ype
<f:facet name="header">
</f:facet>
in the JSP source code. How can I do this visually?
Thanks,
james

The Standard section in the Palette contains the JavaServer Faces reference implementation components. The IDE provides the standard components for backwards compatibility with projects that were built with earlier versions of the IDE. Because the standard components provide less functionality and require more programming, you should use the visual components from the other Palette sections.
I do not know the answer to your second question.

What is the difference between an archive and a time machine backup?

I would like to save a lot of video to an external hard drive and have the drive fill up until it is full and then I'll use another drive to continue to save video. I do not want to backup my entire hd on my mac, just the video. Then when I want to access the video I want to be able to fetch it off the external drive and view/edit it in imovie.
How do I do that?

If you want the videos directly available to iMovie, do the move within iMovie.
Open the Event Library if it is not already, then click on the Hard Drive icon (highlighted in blue on the screen shot).
Then drag your events from the iMovie Events that are under your Macintosh HD onto your external hard drive in the Event Library list. There is some more information in the iMovie Help, under Lesson 7, for organizing your event library.
When you import video from a camera, you can choose to store it on the external hard drive instead of the internal.
Be careful not to select the external hard drive when you are looking for clips. Nothing bad will happen, but iMovie will load all of the video on the drive into the clip window. That takes a bit of time if the drive is full.
Now, you should back up that external in some way since you don't want to lose all your video if the drive crashes. I have been considering a RAID setup with mirrored drives, but I haven't looked that deeply into the idea. Right now, I just copied from one drive to the another as a stopgap solution until I implement a better, incremental backup system.

Exchange Rate difference between PO , GR and IR

Hi All,
I have a question, Does anyone know how to handle the PO exchange rate difference between PO , GR and IR time.
For example
1. PO creation on Jan 2009 - exchange rate = 1.2
2. GR creation on Feb 2009 - exchange rate = 1.5
3. IR creation on March 2009 - exchange rate = 1.7
Should GR and IR use the PO exchange rate # 1 for posting or use the current exchange # 2 for GR and #3 for IR ?
Thank you
Alex

Hi Alex,
The exchange rates in PO and GR and IR will be different as if you have are updating the rates per month in system so it will changed.

"difference between sales order and scheduling agreement "

hi,
i want to know difference between sales order and scheduling agreement and where use scheduling agreement & where sales order ?
please help
amit

Hi Amit,
Its not hard to find this info at help.sap.com
Sales Order
Definition: Request from a customer to a company to deliver a defined quantity of products or provide a service at a certain time. The sales area that accepts the inquiry is responsible for completing the agreement.
Scheduling Agreements
Purpose
A customer scheduling agreement is an outline agreement with the customer containing delivery quantities and dates. These are then entered as schedule lines in a delivery schedule. You can either create schedule lines when you create the scheduling agreement or you can create them later.
You fulfill a scheduling agreement by creating the deliveries in the schedule as they become due. You process deliveries for a scheduling agreement in exactly the same way as you process a normal delivery. After you have carried out the delivery, the system updates the Delivered quantity field in the scheduling agreement item with the delivery quantity. The following graphic shows the document flow for scheduling agreements.
Integration
You would use this component if you had outline agreements with the customer that contained future delivery quantities of materials that would be sent at certain times within a fixed time period.
If you work with scheduling agreements for the component supplier industry you also need to choose the "Electronic Data Interchange" (EDI) component.

Difference between Bucket capacity and Time continuous capacity

Can somebody explain the difference in functionality between "Bucket capacity" and "Time continuous capacity" as used in field "Finite capacity" in "PP/DS bucket capacity" tab in Resource?
How will above above two settings work when you have "Block planning" in "Bucket definition" tab in same tab?
Thanks,
Srini

Hello,
The difference between Bucket capacity and Time continuous capacity are:
Time continuous capacity is basically the capacity which is infinite continuous duration in time and you can define the shift intervals and breaks to adjust as per business process e.g. everyday 8 hrs or 16 hrs capacity with lunch time and breaks in between whereas bucket capacity is a discrete capacity and is specified bucket wise. Bucket capacity can be in PPDS as well as SNP. In PPDS it is used specifically for CDP planning or block planning. In SNP it can be used for bucket capacity references as Transport resources, storage resources , bucket planning etc
With respect to Block Planning:
You maintain the blocks using the entire validity of the available capacity of the resource. If you defined buckets from block planning for validity periods in which no blocks are defined, the buckets correspond to technical intervals in which the system schedules on a time-continuous basis.
You can check out the below link for the Block planning with Bucket capacity:

Any basic differences between AT&T and Verizon, & other questions

I am thinking of buying an iPad mini with retina display (32gb). This would most likely be the only iPad I would ever own. I would use it mostly at the house with wifi, but would like to have one with cellular for when we travel in the US and Canada, and for when the electricity goes out. We currently live in a location where both AT&T and Verizon are viable options, but sometime in the next year we hope to move. The state is rural and mountainous, so as we drive around, my spouse's iPhone (with an AT&T plan) often loses service, but so does my Jitterbug phone, which is not tied to any one carrier (as far as I know). A phone can get a signal in one locaton, but then lose it a few feet down the road. So, there is no way I can choose between AT&T or Verizon based on coverage because both are options right now and there is no way to predict which one(s), if any, might provide service to wherever we end up moving to. Therefore, I'm wondering if there are any basic differences between AT&T and Verizon (or any other of the possible carriers) in what they offer or how they work or what they charge and so on that can help me decide which one to choose since it is my understanding that once I pick one of them for an iPad, that decision can never be changed without purchasing a new device. (e.g., I had read somewhere that Verizon does not allow for voice and data at the same time, but since an iPad is not a phone, is that even an issue?) Also, will the iPad work if there is only regular 4G or 3G service? And will a cellular iPad work without signing up for a data plan since I expect to start with only wifi and then add a data plan later? Thank you.

Alfred DeRose, Thank you for answering the second and third questions. Judging by what you wrote, I am assuming there are no differences between what AT&T and Verizon offer that affects iPads, other than looking at coverage area and the cost of "pay as you go" plans. And, as noted, coverage is not something I can base a decision on at this time. So, I either flip a coin to choose between AT&T and Verizon and hope the result is the right one after we move to wherever we end up finding a place to live, or I continue to wait for another year or more until we actually find a new house before I buy an iPad (or maybe a Kindle Fire HDX 8.9"to save money, but I think I've probably settled on an iPad mini retina 7.9" despite its smaller screen). That does not move me along the decision-making process at all, but it is what it is.
Greatcall has not answered my question about what carrier(s) the Jitterbug Plus phone uses. If, in fact, it uses just the Verizon network, I will try to pay better attention to any possible differences in service areas between that phone and my spouse's iPhone as we travel around the state to see if that helps at all. But coverage is so location specific here that I don't think it will.

Difference between Periodic scheduling & deadline Monitoring.

Hi Gurus,
i want to know the difference between Periodic scheduling & deadline Monitoring.
its gud if u explained with short example.
Thanks in Advance..
regards,
Amol.

Hello,
If you enter the start date or initial counter reading in the scheduling parameters, then you can start the automatic deadline monitoring directly for the maintenance plan (see Scheduling a Maintenance Plan automatically).
If you do not enter the start date or initial counter reading in the scheduling parameters, then you must start the scheduling for the maintenance plan manually before you can start the automatic deadline monitoring (see First-Time Scheduling).
For More Details about Schedulin you can refer below Link [http://help.sap.com/saphelp_nw04/helpdata/en/3c/abb350413911d1893d0000e8323c4f/content.htm]

What is the basic difference between Hyperion Planning and HFM

Hi GURU'S,
what is the basic difference between Hyperion Planning and HFM and when do we choose them.

On a high level the difference is this:
1. HFM is best for global collection (collecting data from scattered entities), group consolidation and for easily structuring financial reporting (mainly consisting of financial data)
2. Planning is best for modeling your business, starting from a demand forecast and arriving to capacity planning and finally to financial statements, by utilizing business drivers (non-financial data like volumes, prices, productivity rates etc)
Of course, differences may be analyzed at several levels down to technical, but the discussion may turn out to be too long, yet adding little value to the question: "when do we choose the one over the other". Bear in mind that your requirements may turn out that you need both.
