Forward Bacward Scheduling.
Dear All,
For material-A
I run mrp using MD02.
For material A i set master data as below:
MRP TYPE:PD
LOT SIZE: EX
PROCUREMENT TYPE : E
IN HOUSE PRODUCTION TIME:2 Days.
GR PROCESSING TIME: 16 Days.
Strategy group:10
Consumption mode:1
Fwd consumption per. :45 Days.
Insert requirement 08.03.2009 -10,000 quan.
After MRP run i got result
In Planned order Hdr tab with following dates :
BasicDates Production dates Other dates
Ord.finish 15.03.2009 17.03.2009 10:12:46 Available for plng 31.03.2009
Start 13.03.2009 17.03.2009 00:00:00 GR processing time 16
Plnd open. 13.03.2009
And in planned order Det Scheduling Tab contains:
Parameters :
Scheduling type:1 Forwards
Reduction:NO reduction Carried out
Scheduling margin :Z05
So,can any one explain In planned order last tab Det Scheduling.
Scheduling type:1 Forwards How it comes?
Bcz i already define in my master Consumption mode:1 Backward consumption only
So,its how trigger with Forwards.
Is it any relation with master or its come with any customizing setting?
and also plz explain in master we define consumption mode when it trigger?
Plz help.
Hi,
I suspect the Start in past check box is not ticked for your plant.
So go to
spro - pp - mrp - planning - scheduling & capacity parameters - parameters for determining the basic dates
Here tick the check box for start in past.
You can do the same via OPPQ as well. After making the settings, re-run MRP with plng mode as 3.
Check & revert if it resolves the issue.

Vivek

I'm wondering if it's possible to set up call forwarding with schedule? For example, calls received at the Skype Number will be forwarded to phone number A from 12am to 12pm, phone number B from 12pm to 4pm, and a Skype contact from 4pm to 12am.
Thanks!Hi, Jimliu, and welcome to the Community,
Fabulous idea! Unfortunately, the Skype Number feature does not provide such facility as you describe.

Forward and Backward Scheduling
I have a couple of related questions.
1. Where can I configure if I want Forward/Backward Scheduling in Customization? and if I leave it blank will it do forward or backward scheduling?
2. Does the system not perform backward scheduling if Replenishment Lead Time (RLT) is setup? If yes why?Hi,
Backward scheduling is the calculation of deadline dates: the arrival time at the customer site is calculated as the earliest
possible goods receipt time at the customers unloading point on the requested delivery date. All four of the delivery and
transportation scheduling lead times are subtracted from the customeru2019s requested delivery date to determine if this date can
be met.
The transit time, loading time, and pick/pack time are subtracted from the customeru2019s requested delivery date to calculate the
required material availability date.
The system calculates backward scheduling as follows:
Requested delivery date minus transit time = Goods issue date
Goods issue date minus loading time = Loading date
Loading date minus transportation lead time = Transportation scheduling date
Loading date minus pick/pack time = Material availability date
Forward scheduling is also done if no product is available on the material availability date calculated by backward
scheduling. The system does an availability check to determine the first possible date when product will be available. This
new material availability date forms the starting point for scheduling the remaining activities. The loading time, pick/pack time,
transit time, and transportation lead time are added to the new material availability date to calculate the confirmed delivery
date.

Scheduled start and Finish date .
Hi Everyone,
I am facing a problem in dates in creating a process order in Production .
In the tcode COR1, when input the BASIC START DATE manually, the BASIC FINISH DATE ,scheduled start date and finished dates should get calculated automatically as per standard SAP.
The problem that I am facing is that , if I input the BASIC START DATE in future , the scheduled start date and finished dates are always coming as the system date.
whatever date I input in the BASIC START DATE the scheduled start date and finished dates are always coming as the system date.
But this is not happening in quality and development server .
Please help me if you have any solution
Thanks
BijayDear ,
1.Scheduling parameter for new process order type and plant combination, to be defined at OPUZ . U can copy the settings at standard order type PI01.Here you should keep Backward Scheduling as Scheduling Type and Keep the adjustment Scheduling as Adjust to Basic Date , depenent requirement Date .
Now Order Basic finish date = Order Basic start date + float before prod + Lead Time of Operations (operation time from routing )+ float after prod.
These floats are predefined in SMK and assinged to material master .It comes through Planned Order after MRP run andcoped to Production Order .
.2.Check and Define Scheduling Margine key in MRP -Carry All over all palnt paremtres (OPPQ)
If you are MTS process , then Keep the Scheudling Type as Forward .Enter the Basic Start date and Scheduling Margine Days ( Opening periods , FBP, FAP) and then hit the Scheduling Indicator .It will calcuate all the dates based on the SMK and operation setup and propose you Basic Finish Date .
So adjust the Flaots in SMK tab in process order , enter Basic Finish Date , Choose Bacward Scheduling to arraive Basic Start or Go in reverse direction by choosing Forward scheduling .
Hope its clear

Best iPad app for Job Timing, "To Do" & Scheduling
I'm contracted to a company as a computer tech, graphic designer and administrator of their computer and accounting systems. I also design and layout their brochures, catalogues and pricelists ready for print. I need to keep track of tasks requested, plus how long each task takes to complete.
Therefore I am needing an iPad/iPhone app that will do the following:
• Quickly enter tasks with a date/time deadline. Input is available to specify priority (e.g +Urgent, High, Medium, Low, When-you-can+ etc). An iCal-like layout would be good. Includes the option of alarms and push emails to be assigned to each task.
• The option of setting as a template a recurring set of tasks for each day. e.g. Daily meeting @ 9am, Process invoices @ 9.30, Update stock levels @ 9.45am etc. These tasks happen everyday, and is set as a customizable template of recurring events, just like iCal's repeating events. Tasks in the template can be edited and will affect all consecutive days recurring tasks.
• Once I begin a new task, the app begins a timer to keep track of how many minutes it takes to complete. It allows for pausing (if I have to answer phones etc, but keeps that task open.) Once task is complete, it automatically marks the task as complete, notes the total time spent on the task and moves to the next prioritized task.
• If a task can't be completed that day or at that moment, you can choose to carry-over that task to another time or even re-schedule to the following day/week/month. When returning to the re-scheduled task, the timer continues from where it left off. e.g. Weekly sales reports couldn't be finished Friday, continued Monday.
• At the end of each day, a +task report summary+ can be exported to A4 PDF and either printed or push emailed, showing each task title, short description (if entered), the time opened, closed, total time taken, and if it is carried forward/re-scheduled.
*Can anyone help me?*
I know this is really specific, but I would be ecstatic if someone, somewhere, had an app that suits!
I'm just so overwhelmed with the variety of GTD and "To Do" apps. I don't want to outlay $ on an app that just doesn't "float me boat."
Any advice from anyone would be very welcomed.
Thanks.It doesn't do everything you are looking for, but I would look at Timewerks: Mobile Billing. It does a lot of what you are looking for.

I have used both. I started out on iTimeSheet and moved to Timewerks because it works better for me to keep track of time spent on a project. -
Scheduling start date and end dates
Hello Gurus,
I am trying to understand the schedule start date and schedule end date functionality in Plant Maintenance. I do understand the basic start and end dates. Currently I set up u201C3.Do not adjust basic dates, dep rqmts to order startu201D and set the scheduling type as u201CForwardsu201D . Please note we donu2019t do any capacity planning or leveling.
So my question is, why the scheduling start date is defaults to the basic start date for forwards and scheduling finish date defaults to basic finish date for backwards ? I tried adding couple of operations and save the work order. It did not change anything in schedule dates.
Do we really need to care about scheduling dates if we donu2019t use capacity planning ?
Please advise
MaheeHi,
As per priority, final dates would be calculated as we will define the duration based on the priprity. Either current date or basic date only applied to Scheduling start date.
You can change the scheduling start date so that based on priority, final date would be calculated.

Maheswaran. -
Hi experts
I'm having issues in the scheduling of PM work orders.
I'm using unplanned WO. They are created from the notifications. Upon indication of operations ( with time for each operation) and components, i set the work order as planning complete (user status). At this point, the system status is created and material availability not check.
When i hit "schedule button" on the WO, i get the message:
Scheduling log does not contain any entries
Message no. C7119
My WO type is configured with the following:
: Ajust basic dates, adjust dep. reqmts to operation date
* Scheduking type: Forwards
* Automatic Scheduling
The control key has the following sets
* Scheuling
* Det. Cap. Req.
* Print
* Print time tic.
* Confirmation required
* Print confirmation
My work center has the following:
* Work Center category: 0005 (Plant Maintenance)
* Capacity category: 002 (person)
CAPACITIES
Operating time: 6h
* Relevante for finite scheduling
* can be used for several operations
* long term planning
On the other hand, when i analyze CM07 and CM25 i always get the following message
There are no capacity requirements for the current selection and
settings
Message no. CY144
I have created 2 profiles to analyze WC loads/Work order leveling - 7 day and 30 day
Even when I use tcodes like CM02, i get the message that no work orders are selected.
So I'm either missing some config or some step.
Can you please provide some clarity on this?
Thanks in advance
JoanaHi
I'm still having doubts.
So, just for my understanding, what should you get from "hitting" schedule button in the WO?
Let me elaborate on my questions (mostly the second one)
I create the the WO. based on the basic dates defined, and the work center capacities, and operations durations, the system will define in the operation detail the dates.
when i n going through CM07 and CM25 i should be able to get the full picture, right? work centers capacities, what is compromised, in which WO?
I get nothing like that. So it seems that althoug i indicate a WC in the WO (it is set for finite scheduling), there is no place where i can get the full picture.
my assumption is that with this info in CM25 i would be able to adjust the scheduling made "automaticaly" by the system (based on my config), to better adjust the work to be done.
Can you provide some clarity on the steps, cause i'm missing something for sure.
Many thanks

Hello everybody,
Our project structures consist of WBS elements only -no networks-. I configured the WBS scheduling profile with "scheduling type = Forwards", and "Schedul. method = WBS determines dates". I configured the project profile with "sched. scenario = Top-down scenario", "planning methods = top-down"
When I create a project, I enter a start and finish date in the project definition area. The project structure consists of 1 WBS element in the first level, and various WBS elements in the second level.
When I try to schedule this project (from the project definition area), the following message is displayed: "
There is no operation for scheduling
Message no. C71462"
I even entered the basic start and finish date in the first level WBS element and perfomed scheduling; I expected to see the start and finish date in all WBS elements, but this didn´t happen.
I appreciate your collaboration,
Nat.Hi RAJ.
The data object J_OBJNR is a CHAR22 field and would leave open many othe possibilities. I have never seen a system with more than 1 Billion (!!!) projects though.
What happens at creation of a project or a WBS element is that an internal object number is triggered and stored in SAP memory. Especially when you do validations or substitutions at time of creation you have to read out this internal number.
Best regards.

Capacity leveling, after Deallocate scheduling dates getting changed.
Dear Experts,
I have a issue in Capacity leveling using transaction CM25 - Online. I have created some production orders (using forwards/backwards scheduling) for overloading of WorkCentre's. When I dispatch orders it’s getting scheduled perfectly, but when I Deallocate same orders scheduled dates are getting changed.
Even after deallocation production orders schedule dates should be the same. Can you please help me in this regard?
Thanks in advance.
PrashanthHello Prashanth,
From SAP help Date Determination in Dispatching and Rescheduling - Capacity Leveling (PP-CRP-LVL) - SAP Library
The current dispatching data is cancelled. The status "dispatched" of the operation is reversed. The order is rescheduled.
If further operations exist for an order which has already been dispatched, the system automatically carries out midpoint scheduling. If no other dispatched operations exist, the system carries out lead time scheduling.
If order date is in past then it schedules to current date during de allocation if you do not have enter number of past days allowed to start date in scheduling parameters.

Concept of just in time in Scheduling Agreements
hi ,
can any one pl help out the concept of "JUST IN TIME "(JIT) , in Scheduling Agreements .hi,
Schedule agreements allow you to have 2 different sets of schedule lines (VBEP-ABART).
In Standard SAP you can have two sets of schedule lines. One Forecast & the other JIT(just in time)
Forecast forwards the schedule lines to planning (seen in MD04) and JIT passes them to shipping (VL10).
They can be identical or different. Typically these are used for component supplier customers (namely Automotive).
The customer will provide you 4-10 weekly buckets (usually a Monday date) of future forecast qtys. Also send you 1-2 weeks of individual FIRM ship dates - which are entered on the JIT.
It comes down to the customer not knowing exactly what they need next week, but they don't want to suprise you with a large order qty, where your lead times are 5+ days. The forecasted qtys they sent last week should account for this.
(2) Cumulative Quantities are tracked and influence how the schedule agreement passes requirements to both forecasting and shipping.
These qtys are sometimes requested by the customer on ASNs. Cumulative qtys reset at year end unless you've got a customer calendar or you've modified standard SAP userexits to not reset.
pls reward points if the answer is helpful

Hi Dears
Please explain in greate details "what is schedule agreements" , "contracting", "How to use Scales in standard PO" and what is scales.
I couln't find the proper explanation in our Forums.
Bye
RajkumarHi
(1) - Schedule agreements allow you to have 2 different sets of schedule lines (VBEP-ABART). Standard SAP you should have two sets of tabs - of schedule lines. One Forecast & the other JIT. Forecast forwards the schedule lines to planning (seen in MD04) and JIT passes them to shipping (VL10). They can be identical or different. Typically these are used for component supplier customers (namely Automotive). The customer will provide you 4-10 weekly buckets (usually a
Monday date) of future forecast qtys. Also send you 1-2 weeks of individual FIRM ship dates - which are entered on the JIT. It comes down to the customer not knowing exactly what they need next week, but they don't want to suprise you with a large order qty, where your lead times are 5+ days. The forecasted qtys they sent last week should account for this.
(2) Cumulative Quantities are tracked and influence how the schedule agreement passes requirements to both forecasting and shipping. These qtys are sometimes requested by the customer on ASNs. Cumulative qtys reset at year end unless you've got a customer calendar or you've modified standard SAP user exits to not reset.
Schedule agreements are very nice when the customer sends EDI data (830s = forecast or 862s = JITs). Outside of that they can really cause trouble regarding daily maintenance, missing requirements, *** qty corrections, year end processing, etc.
One alternative would be to use customer independent requirements - entering the weekly, monthly forecasting qtys and entering standard sales orders (with or without multiple schedule lines) to represent the true firm qtys.
Refer below
http://www.sap-basis-abap.com/mm/gr-creation-for-schedule-agreement.htm
You can fix a price in the info record for a say qty from 1-100 price RS150 & if the order qty is 101- 500- the prices is 140 . Scales cannot be used directly in PO but can be pulled into the PO from various master data like info record, quota arrangement.

APO Sequencing - preventing Takt Scheduling from moving firmed orders?
In the Sequencing transaction (/SAPAPO/SEQ1), selecting the takt scheduling pushbutton will move all planned orders up to the earliest available capacity. I would like to override the standard system logic, and prevent the system from moving any FIRMED orders forward. Has anybody implemented this sort of restriction?
Hi ,
Please refer to oss note 627377 Consulting note: Model Mix planning and Sequencing.
" MMP and Sequencing do not consider in a special way the input fixed and ATP checked orders. No checks are performed whether an order in input fixed or ATP-checked. MMP and sequencing consider such orders as usual orders in the planning processes."
Model mix planning always uses a strategy with forward infinite scheduling, no matter how you define your resources.
