PLANNING CALENDER IN LOT SIZE

Hi
What is the function of Planning Calender in Lot Sizing procedure in SNP.

Hi
You can define the planning calendar to define the periodicity of lot size.
For example in our case we want to SNP to create requirement only in alternate month based on lot size.
So we create planning calendar which consist only alternate month and attach to lot size.
Now when we execute the SNP planning, it will create supply element only in alternate month.
I hope this will give insight of it. Please let us know , if it helps you.
Thanks

Help on Planning Calender and lot size procedure settings

Hi Gurus,
We have 2 different schedule at the moment for our PO Placing to our supplier :
1. Planning Calendar D01 --> For Seafreight shipment, PO Placing on bi-weekly basis, every Monday and RDD (Request Delivery Date) is on Thursday (11 days after PO Placing)
2. Planning Calendar D02 --> For Airfreight shipment, PO Placing on weekly basis, every Friday and RDD (Request Delivery Date) is on Wednesday (5 days after PO Placing)
Now we have required to change the SEAFREIGHT process by having the PO Placing on weekly basis, every Monday and RDD (Request Delivery Date) is on Wednesday (9 days after PO Placing).
Please let me know the step by step procedure to create a new Planning Calendar and Lot Size Procedure to accomodate this requirement?
Thanks for your help.
Regards
Brijesh

Dear Brijesh:
1. I think you are planning to change the Planning calendare D01.
2. For this go to MD26- GIVE THE plant / palnning calendar id.
3. Then in the CAlc rule for spec peroid - change the day from wednesday to Monday.
4. SAve this and generate periods.
5. Now in the maeterial master- check if you have the lot size as PK and also planning calendar as d01.
6. In the planned dleiveyr times you enter 9 days.
Kindly check this and revert back.

Planned order with Lot size and Planning Calendar in MRP

Hi All
I request your help in understanding MRP results in below mentioned scenario:
Material: A
Planning Calendar: D1 (Monday only)
MRP Type: PD
Lot size: Z1 (this is copy of PK with Period Start = Start Date)
Safety Days Time: 3
Safety time indicator: 2
In house Production time: 1
I am running MRP with
NETCH
Planning mode: 3 (Delete and recreate planning)
scheduling: 2 (lead time scheduling)
"My PIRs are:
"Date--------------------PIR   -----Receipt------Avail Qty------ATP Qty ----Actual Cover
"Friday :08.4.11" ---- "-100"   ------ "0" ----   "-100.00" ------ "0" ----   "-5"
"Monday: 11.4.11" --- "-200" ----- "0" -----    "-300.00" ------ "0" ----- "-2"
"Wed      : 12.4.11" --- "0" ---- "370" ---------- "70.00" --------"20"----- "5"
"Thursday 14.4.11" --- "-50" ------ "0" -------- "20.00" ------- "0" ------"3"
"Saturday 16.4.11" -- "-10" ---------- "0" ------- "0.00" -------- "10" ----- "1"

"Friday      29.4.11" --- "-100" ---- "0" ------ "0" -------- "0" -------- "0"
I am executing MRP on 7.04.11
As shown above the, can you please explain why the planned order is on Wed 12th and it covers 5 days requirement and similarly Tuesday 19th and covers 6 days.
I am not able to relate the relation between Planning calendar and Lot size procedure used. Also what would happen if I make planning calendar valid for two days in a week.
Thanks in advance
Rahul

Thanks dear
Yes you are right the Planning Calendar starts 18.4.11 and ends 24.4.11
Now as far as first planned order is concerned I thought it should be scheduled to start&end on Monday 11.04.11, rather it starts&ends on Tuesday 12.4.11. Also the actual coverage days goes up to 5 days even though its maintained for 3 days.
Similarly the second planned order also comes up on Tuesday 19.04.11 and covers 6 days (more than the setting and planning Calendar of only Monday)
On the whole this is confusing me on Lot size and Planning Calendar relation and how it impacts MRP. Can you please help me on this.
Also if you can throw some details on: how to restrict MRP to give planned order only on, say, Monday and Thursday, as only then it could be produced.
Thanks in advance
Rahul

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.

Difference between batch and lot size

What is the difference between batch size and lot size. How do these quantities relate to production planning & machine capacity planning.
Regards

Hi,
Lot size: Some times specific materials are not referred individually but are represented in groups or lots.
When we maintian BOM/production version/routing it is sometime convinenit to maintain compoenent qty / operaion times ect.. for speciifc lots .. we also call them base qty.
we can create different master data for different lot sizes and it is consider in auto selection of this master data in production orders.
MRP can also intiate procurement / production in speciifc lots and this lot size in size is maintained in material master ans lot sizing procedure is maintianed in MRP customiziation.
Batch Size: some times batch size and lot size can be interheprited same in busienss langauge but they have fundamental
difference from SAP point of view. .
In SAP Batch is homoginious non reproducible Unit of material. The batch zise depends on GR qty of the specific batch.

Lot size exclusion from planning run

Hi Gurus
My scenario is some materials are maintained with lot sizes as EX , VB, HB , when planning run executed , the system should not consider the VB and HB lot sizes ( these are not bom components) and no procurement proposal should exist , we are not following storage location MRP ,
Pl come back in full thanks in advance
Regards
Ram

Hi ramki
VB is MRP type not lot size. VB consumption based planning with manual reorder point. The planning proposal will be created based on your reorder level.
HB is lot size of " Replinishment to maximum lot size "
Normally oils and others are procured where the storage tank capacity is restricted. The max replish level will be your max tank capacity. You can define them as cosumable materials or bulk materials.

Lot size key HB with a planning calendar

I would like to be able to continue to use lot size key HB (replenish to maximum stock level), but with a planning calendar in order to specify Friday deliveries. However, the system does not appear to be capable of doing this. Does anyone know a way around the system limitation?
Thanks in advance!

I appreciate the suggestions. I would very much like to use a "Friday" planning calendar, however, if I changed the lot size key to PK - I can no longer replenish to a maximum stock level (unless someone knows of a way to get MRP behavior like lot size key HB but with something like PK).
I also tried using the "Planning cycle" field on the MRP 1 screen, but it appears to require time-phased planning - which again seems to rule out use of Lot size key HB.
Any other ideas?
Thanks again,
Ed

Select BOM as per lot size against planned quantity

Dear all
i hav prob. releated select BOM as per lot size against planned quantity , suppose i hav monthly plnned order for
1000 nos. quantity and having two alternative BOMs like lot size 0 to 500 and 0 to 200 , so after MRP run system should create planned order(inhouse prod.) as per lot size i.e. 500 x1 and 200x 2 ., how is it possible please guide me .
thankx in advanced

create a two production version , if the plan quantity is more than 200 system will take the Alternative BOM and take the BOM ( 0-500 ) otherwise system will take the BOm ( lotsize 0-200).
Or
Create a Production version, Manually change the PV as per your requirement , And rerun MRP with delete a recreate option

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."

Sequence dependent lot-size planning as a basis for PP/DS blocks?

Hi ,
I consider the following system setup for a Mill Products planning implementation .
1) In SNP one performs SOP planning with common goals to adjust sales plan, establish equipment maintenance plan, transportation plan, etc. The first month of the SNP plan is supposed to be in daily buckets. Using the SNP optimizer is a good option since the business goal is to use equipment more efficiently, let's say to minimize setup costs, and there are warehouse limitations for semifinished products as well.
2) In PP/DS we are going to use CDP and block planning since it is the best practice.
3) SNP planned orders can be used as a basis for PP/DS blocks on the resource, upon the condition that the configuration of SNP product - kmat variant and block requirements match.
In SNP i see that the SNP PDS has a duration of 1 day (that's fine), but the sequence dependent lot-size planning requires a bucket of at least 1 week long (1 month in my case) since the SNP orders are sequence-optimized only inside of one bucket. The result of such an optimization are additional counters assigned to SNP orders according to their sequence minimizing setup costs. However, orders are not scheduled according to the sequence.
So far it looks like such a combination is not useful as
- Orders in monthly buckets are not scheduled on days and cannot serve as a basis for block dates proposal for PP/DS block planning.
- If a product production volume is less than 1 day, SNP cannot create any more detailed block in principle since the minimal time bucket is daily bucket.
I searched over forums on these or similar topics, however no definitive answer so far for the question in the subj.
Could anyone bring more light on this ? Maybe I am missing something in the setup or sequence dependent lot size planning was designed for other purposes/industries?
Best regards
Vladimir

Hello Asim,
Issue one
in product selection for propagation range you can set your selection criteria which selects the products dynamically. You just have to change your report variants for planning run. Do I misunderstand your concerns?
Issue two
Changing to planning procedure 1 will not delete the PFE but will prevent APO to create a new entry after any MRP-relevant changes happen or heuristic SAP_PP_020 (which creates the initial entry and does the low level code determination) is run.
In some cases procedure 1 will still create a PFE. Please check customizing for details. Thats why I would recommend to create a new planning procedure with "no reactions".
As soon as you prevent APO from creating new PFEs you can just once delete the PFEs in /SAPAPO/NETCH by just setting the first column for these materials blank (select your materials, mark column, delete indicator).
Corresponding table to MDVM is /SAPAPO/PEGKEY. Indicator for PP/DS is NETCH_RRP.
If material is not planned in APO you do not need a PFE in APO.
Issue 3
Maybe utilize table /SAPAP/PEGKEY
As I said if you prevent creating the entry you just have to delete (set indicator blank) once.
Hope that helps.
Regards,
Uli

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...

Lot Sizes Used for Fore cast planning

Dear all,
<b>For fore cast planing and Automatic reorder point planning what are the lot sizes are use full and what are the advantages and effects for each lot size procedure.</b>
I am expecting answer for this question from all of you.
Regards,
Krishna

Hi
These fore cast planing and Automatic reorder point types are consumption based planning.
Hence for these MRP types normally, lot for lot ( EX ) will be used.
You can go through the following link for further info on lot sizing procedures.

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 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.
