CTM Planning: How to Handle Min Lot Size Daily Resource Capacity?

Hello,
I am facing a situation where the Min Lot Size values require more than a days capacity of the Resource.
Finite Planning CTM is skipping all demands.
Example:
Daily Resource Availability = 24 Hrs,
Capacity Consumption per PPM = 1000 Kgs / 1 Hour.
Min Lot Size = 50,000 Kgs
Capacity requirement for the 50,000 Kgs = 50 Hrs
Is there a way CTM can plan this?
Thanks,
Ran

Yes the time buckets in CTM profile has nothing to do with this limitation...
Nor does the infinite/finite setting.
Basically its a limitation of how the resources are stored in livecache.
You can not exceed the capacity for which the resource is stored...
The only workaround is to define the resourcde in weekly time buckets by manually defining a capacity profile.
I don't like this as every order will take a week...
I am not aware of any other workaround...
I have seen other clients take out the minimum lot size for SNP, then when cif transfer the order back to R/3, it is combined to 1 large order...

Min Lot Size and Rounding value

Hello MM Gurus
need a small help!
I m a bit confused regarding the use of Min lot size and Rounding value in material master "MRP 1" view..
can some body teach me a detailed functionlity for both..
As both serve the purpose ..for e.g. my requirement is 7 and min lot is 10 system will create proc.proposal for 10
in similar way if i use rounding value as 10 , then als system will create proc.proposal for 10 only even if requirement is 7.
grateful if you could pl expain me the functionality of both...
another query..if I use Min lot size in material master will the same will serve the puspose of <b>min order qty ( maintained in PIRs)</b>
i'lll appriciate with good reward points...thanks in advnace

Sumit

Helo Guys..
Thanks for valuable inputs..
i have assigned the appropriate rewards ..
pl clear my this doubt also
e.g. for a materials
Min Lot size - 40
Rounding value 25
requirement is for - 35
will it be 40 or 50 ..i understand 50..
j
ust anothe rquery..pl treat this separate issue..and separate rewards will be given
<b>can I use max stock level w/o use of lot size "HB"</b>
e.g. if my max stock level is 80
and min lot size is 30 and current stock is 60
what'll be my proc proposal created by MRP , i dont want system to cross 60 stck,,
Thanks in advance

MRP planning Purchase REQ per fixed lot size

Folks,
I have materials which have MRP type PD with fixed lot size of 20 pieces. Safety stock = 200 pieces. MRP run results in 10 preqs of 20 pieces each. I would like to have 1 Preq of 200 pieces. How can this be achieved?
Regards,
MdZ

Hi,
This is because of Lot size "FX" you maintained as 20.
For FX lot size system will divide the total qty as per the fixed lot qty & throw that much of PR for that stock.
So Safety stock = 200, FX =20 so PR will be 200/20 = 10 PRs
If you want 1 PR for your safety stock, then change the Lot size to "EX" then system will throw 1 PR for 200 qty as per your Safety stock

How to handle a lot of menuitems.

Hi,
I am in need of a solution that can handle a lot of menuitems on a mobile device.
My vision:
At the bottom of the screen there is always a Menu button. When clicked a list pops up above it and the background fades.
Looking for something like the windows start menu but when clicked the active screen fades. (Like an alert popup does in a regular air desktop application)
What is the best way to achieve this?
one of my thoughts;
- click on first tabbar menuitem with the name Menu
- take a snapshot of the current screen
- launch a new view
- put the snapshot as a faded background in the view.
- above the first item in the tabbar (menu) draw a list with other menu item buttons that lead to other views when clicked.
I'm building my first mobile app.. so exiting.. but a bit of a pain to get the right help.. Is there a page with help on only the things you can use on a mobile project? And skinning... what about that?? Flex 3 was so easy to layout the look and feel of your application..
Off topic Note for someone from adobe;
Is there a style explorer that outputs a skin? For example style a button the way you like with sliders, color pickers and stuff.. and it outputs a skin for it to copy into your project. Would be verry nice to have.

Why not just have a hidden solid color box over the whole background that you set to blackbox.visible = true when the button is clicked and set its transparency to 50% so the background looks darker now and the user can focus on the pop up. Or set it to white so the background looks light and washed out, depend on what look you want. You can also tween it to the 50% and make for a cool effect. Then when the user selects a menu item, or taps outside the pop up menu, simply hide that box blackbox.visible = false or tween it to an alpha of 0 and then hide it.
I have something similar in one of m apps, pm me if you want a link.

How to handle different screen sizes?

Hi,
I have a couple of 2D 180X180 png images. I used them for splash screen, backgrounds etc etc. How do i ensure that my splash screen and background (using these fixed-sized images) can cover the device's displayable area? For example, if a device is 200X200, how do i stretch my 180X180 images?
I'm currently using lcdui's Image class to display the images, and there isn't any method that i could use to scale the images for different device sizes. :-(
Thanks for any help!! :-)

The way this is usually handled is with different versions containing graphics fro different screen sizes.
You can resize images using MIDP 2.0, but this method is a memory hog, and with an image as big as 180x180 there is a big risk of running out of memory during the process.
Or you can work out a way so that the screen resolotion doesn't affect you. Like centering the image over a background of the same color as the image's background, using tiles to create the background, etc.

HOW TO DEFINE THE LOT SIZE THAT CONSIDERS MAX STOCK AND IN FIXED LOT

Hi Gurus,
I have a requirement where the client wants to procure the material in fixed lots of 125. they are using manual reorder point VB with reorder point of 100. The maximum allowed stock is 400.
When the MRP runs they want to generate a PR that is close to 400 and also a multiple of 125. I tried to use FX and it is only generating procurement proposal for 125. When I use HB it is considering the max stock but not generating the proposal in multiples of 125. Can anyone help me out with this.
Regards

Hi,
I think your problem could be solved by using rounding profile but not using
fixed lotsize.
In rounding profile you have to give threshold value and rounding value
For the threshold value 1------- Rounding value 125
            threshold value 126------Rounding value 250
            threshold value 251-------Rounding value 375
            threshold value 376 -
Rounding value 400

Reorder Level Planning with Min. Lot Size

Hi All,
I am trying to configure MRP Run. I am maintaining following Data
1. Reorder Level
2. Maximum Stock Level ( stock beyond which PR cannot be raised or stock cannot be maintained.
3. Min Lot size (lot size of which PR should be raised.
can anybody please help.

Hi
Max.stock level can be use with lotsize HB not with VB. But you can use max.stock level and minimum lot size with reorder point planning.
Ex. Reorder point -10
Max. stock level - 20
Stock -9
When the stock level goes below 10, system will create a P.R to topup the stock value for 20.
Ex. Reorder point -10
Min.lot size - 5
Stock value - 9
When the stock level goes below 10 ie, 9 , system will create a P.R to topup the reorder point. But the min lot size is 5. So P.R will generate with quantity 5.

Planning time fence and Lot size

Hi,
MRP type=P3, Planning time fence=28 days, lot sizs=EX and all 28 days are working days.
so today =05/112009 and i check the MD04 End of planning time fence is 03/12/2009
But when i change the lot size to =ZC(3 Months lot size) keeping the rest all same as above.
and when i check MD04 The planning time fence moved to 01/01/2010
What should be done to keep the planning time fence as 03/12/2009 and i don not want to change either MRP Type or lot size
Regards

Praveen,
I think your Lotsize Indicator is based on Planning Calendar. Please check the period definations of the planning calendar assigned to the material in the MRP2 view.

Fixed lot size key has no effect on planned orders generated for VC PIRu2019s

Hello gurus,
does anyone have an idea why the fixed lot size key is not having an effect on the planned orders that are generated for the Planned Independent Requirements (PIR) for MTO configurable materials. My client is using planning strategy 56.
I have copied & customized the Fixed lot size key FX to suit the MTO production (u201CLot size as in short-term periodu201D activated) that works nicely even with configurable materials when a planned order is generated for a sales order. But the planned orders in the preplanning segment, i.e. that were generated for PIR's, are still created equally to the PIR quantity.
Is this behavior an error or an SAP feature? Though, I have reviewed the OSS Note 437098 that might be related to this. Can anyone tell me if it is related to this issue?
Regards,
Mikko

Got the answer fro SAP:
Please consider the following note, which provides the explanation about this behavior of the lot-size, when VSE requirements are used:
125498 - MRP/Docu: Planning segment and lot-for-lot order quantity
The following section of the note describes your scenario in detail:
"The planned independent requirements for a material are in a separate
planning segment (planning strategy planning without final assembly,
requirements type VSE, VSEV).
You enter a rounding value or a rounding profile or an lot size that is
not exact in the material master.
Material Requirements Planning:
In Material Requirements Planning, planned orders are generated for the
planned independent requirements. The lot size settings (such as fixed
lot size or minimum lot size) are also not taken into account."

Planning time fence with Lot size MB

Hi Friends,
I am facing one issue as below,
I am using MRP type P3 , Planning time fence is 20 days , Lot size is MB (Monthly). I am not using MRP group.
Planning time fence should be calculated as Todays date+Planning time fence on MRP1 but if the calculated date with this formula is going in next month system takes first date of next following month as Planning time fence (effect of lot size MB).
WIth lot size EX , it works fine.
Can we avoid shifting of Planning time fence to first date of following month with lot size MB?
Thanks.
Sandeep

I got a workaround , I have used 2 lot sizing procedure in a sigle lot size. Daily lot size (for Short term) and Monthly lot size for Long term. For short term requirements are grouped for 28 days. Closing the thread. Thanks.

CTM planning related conceptual questions

In an attempt to understand the CTM functionality for master planning I have the following questions
1.In real implementation where is the safety stock planning done by the standard methods and the where are the service levels considered.
2.when is the lot for lot/fixed lot/reorder point and by periods?
3.when is the planning mode strategy like the replan all orders or orders with fix pegging used. is it based on the replenishment lead times of the products?
4.when is the delete only the un firmed orders used?
I understand that it is industry specific but an explanation with reference to the industry would be helpful. idea is to understand the business logic behind this configuration.

typically service level based Safety Stock planning would be used in situations where replenishment leadtimes are variables. there could be SLAs with the supplier as well. standard Safety stock planning would be used under relatively static conditions of leadtimes. One would use days' of cover in situation where net requirements could be varying a lot with time. One could also use quantity based static Safety stock quantity, in situations where the product has high volume net requirements. One could use time-phased quantity safety stock/days' of supply where conditions are dynamic throughout the year in terms of demand and supply.
Regenerative planning is to do planning from scratch by getting rid of all unconfirmed and confirmed planned orders/requisitions. Non regenrative planning would be doing incremental supply planning based on increased/decreased demand.
Lot for lot will be used when the planned order quantities do not have any size restrictions. so they may go from a certain min lot size to a max lot size. So there is just one planned order to meet the demand. In fixed lot size, there are possibilities of multiple planned orders of same size to meet the demand. Reorder point method will mean that planned orders get created when stock and scheduled receipts fall short of an expected level of projected stock.

Rounding Value,Minimum Lot Size and Maximum Lot Siz parameters

Hello Gurus,
Please explain me the what is the use of the parameter Rounding Value
,Minimum Lot Size and Maximum Lot Size parameters in the product master and how does it in impact during the Heuristic Run?
Thanks.

Rounding value is the incremental quantities in which the order can be produced/procured. Eg. if orders are possible with quantities 40,60, 80, 100 etc..then rounding value is 20.
Min lot size is the minimum quanity in which order can be produced eg. 40 in above example
Max lot size is the maximum quanitity in which the order can be produced/procured. eg. 100 in our example
Impact on Heuristic run: heuristics takes all the above parameter to plan supply order. eg. if requirement is 55, it will supply plan for 60. If requirement is 120, it will produce two orders - one for 100 and the other for 20. if the reuqirement is 10, the order size will be 40.
Hope this helps.

Rounding Value is not considered for MB lot size

Hi
I have a scenario where MB (Monthly Lot size) lot size is used with rounding value. Example as below:
Lot size: MB
Min Lot size: 15000
Rounding Value: 20000
DEMAND: 16000
When MRP run, System is creating the 16000 as P Req instead of 20000 which is the rounding value.
Pl let me know, if I need to apply OSS note / any other solution for this.
Thanks,
JK

Dear ,
Are you using any Rouding Profile in MRP1 view ?
What is the Setup in OMI4 for MB-Lot Size .Remove the tick mark in Last Lot Exat if it is marked .By specifing the rounding value, the system will determine during lot size calculation that lot size qty is a multiple of of an order unit(eg : pallet size if mtrl is delivered in entire pallets...).
Please check what is the Lot Size Indicator or Lot size procedure assinged to it ?
2.you can use rounding profiles...its used to define the setting of rounding up or rounding down the order proposal qty into deliverable quantities...rounding profile maintenance the t-code is OWD1. Here for static rounding profile
Rounding profiles are defined under:
spro-> purchasing->consumption based planning->planning->lot size calculation ->maintain rounding profiles...
it consist of threshold value and rounding value...
the threshold val is the value from which the system rounds the value of the next deliverable units upto...
the rounding value is from which the systemshd round up to as soon as threshold value is exceeded...
Otherwise , Check FM MD_ROUNDING_VALUE

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.
