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.

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

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"
"Sunday    17.4.112" ---- "-10" ------- "0" ------- "0.00" ---------- "0" ----- "0"
"Tuesday   19.4.11" --- "0" ------- "2000" ------- "2000.00" ------ "2000" --- "6"

"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

How to know if a MRP run element is using Quota Arrangement and lot size?

Hi all,
Two questions:
A) How to determine if a source is actually pulled from Quota Arrangement?
I am wondering if there is anyway from ABAP table or from Transaction (i.e. Purchasing Order) in which the source is pulled from a Quota Arrangement?
We use scheduling agreement, PIR and source list, and as well as Quota Arrangement for our purchasing.
I just want to know how, from system (table and transaction), to find out the source is from quota, not from PIR or others.
B) Quota Arrangement still can work properly if lot-size procedure's splitting quota indicator not Checked?
If my the lot-size procedure which I am using for a material does not activate the splitting quota indicator, it means split quota will not work during MRP run.
But does this also mean that quota arrangement will not be working for this particular material even if I have create a a quota arrangement object (via MEQ1) for this material?
Thanks
Daniel

Tomek,
If I want to use the split quota, it seems there is some pre-requisite.
If you go to MEQ1 and press F1's on the "Minimum qty split" column, and you will notice the following message.
Allocation by quota using splitting quotas is only carried out via a requirement planning run, subject to the following preconditions:
Through the appropriate entry in the field Quota arrangement usage (on the MRP data screen 2 or Purchasing screen) it must have been specified that a quota arrangement is to be applied in the planning run.
The indicator for the splitting quota must be set for the the lot-sizing procedure used for materials planning purposes in Customizing.
Hence, the quota arrangmeent still workable even if the lot-size does not have the spliting quota box checked?
Indicator: Splitting quota in short-term horizon
The indicator for splitting is used to determine that in the case of the selected lot size, the quota arrangement is to be applied using the splitting logic.
Use
If this indicator has been set, the lot is split up in the planning run according to the following formula:
quota for source X
Quantity for source X = --------------------- * requirement
sum of all quotas

Lot size procedure & MRP

Dear All,
What is Lot size procedure and how it will affect during MRP run?
Please provide some example against explanation.

Suppose,
Avaialble Stock= 50
PIR 150 on 25/06
PIR 60 on 27/06
When you run MRP,
                             Avaialble stock
PIR 150 on 25/06       100
Planned ordre 100       0
PIR 60 on 27/06         60
Planned order 60        0
For 1st PIR, The NEt requirement is 50-150=-100, So planned order for 100 is created.
For 2 nd PIR, the ner requirement is 50-150-60+100= -60, planned order for 60 is created.
In toto, net requirement = Stock-total requiremens+ Total receipts

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.

Re: Coll. req with WB lot size procedure & minimum lot size

Dear All.
I am having a material assigned to WB lot size procedure with collective requirements indicator & a minimum lot size qty.
Now still the system are creating more than one PR in one period. Please advice.
Regards
Vivek

Hi All,
What is happening in thsi case is that inspite of the desirable setting for getting Collective requirements with WB LSP. The system is creating lot of Purchase requisitions for one day.I want that the system should add up all the PR & prompt only one.
Please Advice.

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

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.

'Start of Lot Size Grouping' and 'Lot Size Strategy' parameters

Hello,
For "by period" lot sizing procedure, could anyone explain the difference between:
- "Start of Lot Size Grouping" flagged with "Lot Size Strategy": 1
- "Start of Lot Size Grouping" flagged with "Lot Size Strategy": blank ?
I have played around with both options and both produced the same result. If anyone could provide some insight , I would appreciate it.
Many thanks in advance.

Hi Datta,
Thank you for your help.
You indicated that the "The first period of the grouping horizon can be different than the period in which demand exists".
How would the first period be different? What other elements could be considered for the start of the horizon?
For example,   Periodic Lot of 4 weeks, Lot Size Strategy 1 or blank and Start of Lot Sizing Group Flagged produced the exactly same result. What is interesting about it, is that with Lot Size Strategy "blank" the group production quantity is placed in a bucket where there is no demand. The results with Lot Size Strategy "1" makes sense as I have the grouped quantity placed in a bucket where I have shortage due to Safety Days requirement and not necessarily demand.
                             w1     w2     w3     w4     w5     w6         w7            w8
Total Demand     125     42     42     41          110     37     73
Production (Planned)     223                    244
Days´ Supply     58     53     48     43     58     53     48     43
Safety Days´ Supply     43     43     43     43     43     43     43     43
Any thoughts? Many thanks in advance.

BOM explosion report and lot size

Hi all
We have created a Z report for BOM explosion . Here it gives the user the option to explode the BOM at the desired level.
We have an enhancement ticket where the user wants an additional field of Minimum lot size and Maximum lot size in the report.
Before assigning a task to the ABAP team , I request if some one explains the feasibility and its impact on this report. Thanks in advance .

MRP: lot size procedure

Hellow everyone,
I have to configure MRP for some materials. The problem is that we need to create an automatic purchase requisition when the stock level goes beyound a certain safety quantity and the proposal must be a result of the average quantity of the last three months sales plus a 20 percent. Example: the last three months sales average = 5000 kg then the quantity proposal must be 5000*1.2=6000kg. I also don't know if I can configure this in standard SAP or if we need the help of an ABAP consultant.
Thanks!
Edited by: Dean John on May 24, 2010 10:19 AM

hi,
for your requirement there is the concept of range of coverage. this is nothing but the dynamic safety stock.
please follow the link

and there are many in this regards.

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.

Relation between PO Qty and Minimum Lot size of material master

I have maintained "100" in minimum lot size ( MRP1 View, table MARC and field BSTM) for the material.
I am also succssed to create the Purchase order for 2.5 Qty for the same material. '
I wanted to know, how system is allowig to create the PO with lesser qty or is this view is maintained only for sales?
Please give your expert comments on the same.
Thanks,

Used for claculate the procurement qty during MRP and depends on the lot size procedure you select. quota arrangement also uses this lot size.

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.

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."
