Fixed Lot Size and Assemby Scrap

Hi Gurus,
I've an issue using a Material with Fixed Lot Size (MRP View) and Assembly Scrap.
The system doesn't increase the base quantiy (creating a Process Order) with the Assembly Scrap defined in the Material Master, if you change manually the quantity in the COR2 quantiy will be recalculated correctly.
Anybody can help me?
Thanks
Marco

dear marco,
One changes in my earlier post
IF fixed lot size is 1000, and assemby scrap as 10 %
if the pir is for 900
after running MRP system will create a plan order for 1000
In MD04 , you can see the receipt reqmt as 900 and scrap as 100
i.e System will allocate the scrap with in the fixed lot size
Once the plan order is converted in to process order you can see
the total qty as 1000 and scrap 100
for other lot size system will add the PIR reqmt +assembly scrap %,
Yes you can change the qty in COr2, system will update as per the scrap qty , i.e system will allocate the qty for scrap
for ex , if you are changing the total qty as 10000, system will propose 1000 as scrap,
when you save the order and see the mD04
you can see the receipt/ reqmt qty as 9000 and scrap as 1000
i.e system will allocate the 1000 qty from total qty
Hope you are clear how the fixed lot size is working for assembly scrap

Fixed lot size and Minimum lot size

Dear senior,
My client has the following scenario. His supplier provides the item in a fixed lot size of 100. The minimum lot size to be ordered is 300.
The supplier is a fixed vendor.
I tried to maintain this information in the Material Master MRP views. Lot size - FX, Fixed lot size - 100, Minimum lot size - 300.
However, everytime, the minimum lot size will get reset.
Is there any way , I can maintain this scenario via configuration or any other method?
Thank you.

Hi,
Fixed lot size - 100 means for every 100 quantity system will create one purchase document.
If you selected Lot size - FX - Fixed order quantity , then no need to maintain Minimum lot size & Maximum lot size fields.
Then you have to maintain Fixed lot size filed only.
Ex:
Lot size = FX
Fixed lot size = 100
There is a requirement of 300. Then system will create 3 PO's with quantity of 100 each.
If Lot size is Ex - Lot-for-lot order quantity, then only need to maintain Minimum lot size & Maximum lot size fields in the MRP 1 view.
Ex: Lot size = EX
Minimum lot size = 60
Maximum lot size = 100
There is a requirement of 250. Then system will create 3 purchase documents, two documents with the quantity of 100 and third one with the quantity of 60.
That's why, in your case system is reseting Minimum lot size every time.
If you want to maintain Minimum lot size, then maintain
Lot size as EX
Minimum lot size = 100
Max lot size = 300
It will solve your problem.

Combination of Fixed Lot size and Period lot size

Dear all
I have scenario as follows:
1. My supplier's standard packing size of a raw material is 1000 EA.
2. I want to follow period based lot size to optimise my order and inventory cost. But I don't want to use dynamic lot size which will propose dynamic quantity.
So my requirement is like I want to fix lot size as 1000 at material master and Period is Week. My proposal quantity must be 5000 EA for the following demand pattern:
Week 1:1200
Week 2: 1000
Week 3: 1100
Week 4: 1000
System must consider period as well as fixed quantity.
Kindly throw some light on this.
Advance thanks.

Hi
1.As you are looking for Weekly demand demand quanityt , you have to assign Weekly Lot Size : WB.
2. Goto OWD1 and Create a Rounding Profile which will rounds into Weekly Demand quantity for that plant and simulate .
3.Assign this rounding profile in MMR in MRP1
3.DO NOT assing rounding valu as 1000 .Rather keep it blank
Hope this will solve the problem

Report for Reorder point, safety stock, current stock and fixed lot size

Hi,
Purchasing Dept. is looking for a report which can give list of materials falling below the reorder point, so that they can go ahead and create procurement proposals for those materials.
They also want to see the Reorder Point, Safety Stock, current stock and fixed lot size in the same report.
Let me know if there ia any standard report availbale which displays the same or any approach to get the same.
Thanks in Advance.
Regards,
Shankar Goud.

Hi,
There is no standard report because this is meant to be managed by the MRP run.
The MRP lists show all materials that have a problem (such as stock below reorderpoint) but MRP generates requirements for these anyway and so all you need to do is to look for the MRP generated requirements (requisitions?) and you have your list?
Are you using MRP?
If so then please use the standard functions in MRP to get this.
If not, then WHY NOT?

Different fix lot size depending on the production version

Hi all,
I have the next scenario:
2 production versions. 2 different fix lot size por each. So:
Prod Version 1 - Fix lot size 200
Prod Version 2 - Fix lot size 300
I created the Quota Arrangement just to make SAP to take my favourite version. And trought the quota, I can define the lot size for each version. BUT.
If I change the version in the order or in the planned order, the quantity don't change.
So: How can I manage 2 different fix lot size for 2 different product versions? If I change the version once the order is created, how can I do the system change de quantity to the right one?
Thanks in advante
<< Please do not offer points >>
Edited by: Rob Burbank on Oct 1, 2010 2:53 PM

I have n't tried this scenario,
This is my Idea
Create a two production version
for ex: lot size 100 to 1000, set the rounding profile qty as 1000
for lot size 1001 to 99999, set the lot rounding profile value to 5000
BY this way u can get the two lot based on the rounding profie
Expert; please correct if i am wrong

Fixed Lot Size

Dear Gurus,
I am simulating the functionality of Fixed Lot Size so I enter Lot Size = FX and indicated Fixed order Quantity = 40,000 in Material Master. We are using Ind./Coll = 1 and I want to generate fixed quantity of planned order equal to 40,000. But when I run MD42, the system still generated planned order equal to the shortage/required quantity. Our requirement is to generate fixed quantity of 40,000 per planned order regardless of demand requirement.
Please help. Thanks in advance.
Regards,
SD

Hi,
Please find my reply below,
Use MRP Type VB:Manual reorder point planning:Here you need to define reorder point in material master in MRP view.When the stock level reaches the re order point then system will create a procurement proposals.

SNP quota arrangement with fixed lot size

Hi all,
i have a question regarding quota arrangement for external procurement in snp heuristic. Whe have 2 sources of suppy created by info record. The quota is 25% for the first and 75% for the second one. In product master there is maintained a fixed lot sice of 500.000. Im wondering that the snp heuristic creates 2 requisitions of 500.000 for each sos at the same day. So we get an serios excess. Any ideas?
Kind regards,
Christian

Hi,
thanks for reply. Ok, normally net requirement calculation works properly. In case of a shortage the heuristic shall apply an receipt with the fixed lot size wich is maintained in material master. However, in out particular case it generates the double receipt quantity which is not needed at the receipt date.
The heuristic should do the following:
Day 01 Stock 100
Day 02 DepDmd 20
Day 03 DepDmd 20
Day 04 DepDmd 20
Day 05 DepDmd 20
Day 06 DepDmd 20
Day 07 PurReq 100 !! Source 1!!
Day 08 DepDmd 20
Day xx PurReq 100 !! Source 2!!
and not:
Day 01 Stock 100
Day 02 DepDmd 20
Day 03 DepDmd 20
Day 04 DepDmd 20
Day 05 DepDmd 20
Day 06 DepDmd 20
Day 07 PurReq 100 !! Source 1!!
Day 07 PurReq 100 !! Source 2!!
Day 08 DepDmd 20
In this example 100 would be the fixed lot size from material master.
Best regards,
Christian

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."

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.

Default costing lot size and price unit as 100 in material master

Hello,
The costing lot size and price unit is "1" by default in material master. Due to this in CK11N the costing lot size is coming as 1.
Then we go to MM02 and change the master by making costing lot size as 100 and price unit as 100.
Please advise how can we make this default as 100 instead of 1 in material master. So that everytime we don't need to change.
Is it coming from BOM?
Please suggest.
Regards,
Tapan

Hi Tapan
No doubts, it is ABAP's responsibility to develop it.. It requires ABAP code to be written
The functional specifications need to be given by you.. This BADI is called during Mat Master Creation/Change.. Your Func Specs should cover
1. Which Mat types it should be used for
2. The costing lot size and price unit to be defaulted...
I used it to check Plant = Profit Center and it worked... For whatever checks and validations required during Mat Master creation, this badi needs to be used

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.

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

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
Br
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

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"

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

QR Code capacity with fixed rendered size and dynamic data

There's a paper forms barcode and symbology is QR Code, layout is 46mm x 46mm, error correction level is M, module width is 0.592mm, and max capacity is Chinese(UTF8) x 88 or number x 627 or uppercase A x 380 or lowercase a x 263, and QR code renered size is about 30mm x 30mm when max capacity.
So, my question is, if I want to ALWAYS keep this QR code renered size is same as max capacity(30mm x 30mm), but my daya is dynamic and mix numeric, alphanumeric and byte mode, is there any formula to calculate how may character such as space should be appended?
thanks

The more data you stuff into the barcode, the bigger it will be. I am not sure that there is a formula you can use to calculate how much buffer space you need to keep the barcode the same size. At least I have not seen one.
For Designer, we offer these guidelines when using paper forms barcodes: http://help.adobe.com/en_US/livecycle/9.0/designerHelp/index.htm?content=000342.html
