Rounding in CBP using HB lot size

hi
we are using following data for a material:
MRP Type : VB
Lot size : HB
ROP= 2
Maximum stock level = 26
Current stock = 1
my requirement is as follows:
whenever i will run MRP , proposal should be generated in multiples of 10
e.g. if I run MD03 in above sitiuation, I want that proposal should be generated for only 20
tht means future stock = 1+20=21 (which is less than Max stock level = 26)
and order will be in multiples of 10.
pl suggest

Hi Mario,
Yes.....you are right...if we maintain rounding value as 10 ...it will generate proposal for 30.....we do not want the system to generate proposal (30) greater than max. stock level (26).
In this case system should generate proposal for 20 only (which will be less than 26).
Can u plz suggest?

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

Use of max stock level w/o lot size HB

hello champs..
need a help on below functionality
Can I have the functionlity of max stock level without using "lot size - HB" in material master.
my requirement..tht system should not create any procurement proposal if stock reachs at max level..
but with this i am using min lot size also..and this functionality got vanish if I use "lot size=HB" ..system dont see min or max lot size..it just create the proc proposal for the qty upto max stock level..
my requirement
for a material max stock level -100
min lot size - 50 , max lot size 80
and if my stock is 30 ,and my reuirement is for 80..system should not cross the max stock level and should create the prc proposal for 70 only..
pl share your thoughts on this..I'll appriciate wih necessary reward points..
Br
Sumit

Hi
thanks for reply..but i am not sure whther w/o using HB max stock level will be considered or not..
i yet have to test the same but as per SAP , if you want t maintain themax stock level in the plant , lot size should be EX
is this undertsnding is okie..
thx in advance

Rounding value and Minimum lot size

Hi all,
Finish material is X and Raw material is Y.
Bom- For Preparing Xu2019s 1 Qty, 1 Qty of Y is required
In Material Master of Y - Rounding value and minimum lot size is 10,
Project needs 5Qty of X.
When MD51 for Project execute u2026 PR of Y must be of 10 as per rounding value and minimum lot size, but it is creating PR of 5 qty.
Above scenario working properly if I take MRP run with MD02 for material X for 10qty, after MRP PR of Y will be created for 10qty.
With Regards,
Ashish

Dear,
By default, the lot size works as lot-for-lot quantity in the make-to-order and project scenario.
Go to OMI4 select your Lot size and define Lot Size: SOP 1 or 2Lot-for-lot with rounding. Better create new Lot size as ZX with these setting.
If you always want lots to be created for the multiple of the rounding value, you must specify a minimum a multiple of the rounding value.
Example: minimum lot size: 10 and rounding 10.
Please try and come back.

Material Cost Estimate with different lot size.

What happens if the material cost estimate is run twice using different lot sizes each time (all other parameters unchanged) for the same period?
Will the cost estimate run later overwrites the results from cost estimate run earlier (though the lot size is different)? What is the role of lot size in a material cost estimate?

The costing lot size impacts your cost estimate if you have lot size independent costs (i.e. setup cost). Those fixed costs are spread over the costing lot sizee to give you a cost per unit.. Larger costing lot sizes can also help you minimize rounding issues.
You can only have one marked cost estimate in a given period. However, you can create and save a cost estimate as many times as you want as long as you have not marked it for release. When you save the estimate it will overwrite an existing estimate. You also have the option of creating multiple estimates under different versions or with different costing variants.

Lot size creation in PP

Hi gurus,
I have 2 scenarios,
1. PIR of a product X is 56 & lot size is 10. After running MRP, SAP should create 6 plan orders of qty 10.
2. PIR of a product X is 54 & lot size is 10. After running MRP, SAP should create 5 plan orders of qty 10.
Means,
Balance qty after lot size calculation, should be round off to the next lot size if it is greater than 50% of lot size.
Similarly Qtyshould be round off to the previous lot size if it is less than 50% of lot size.
Pls help
Regards,
SamieR

Dear Samie,
Case1: As explained by our other forum member you use a fixed lot size and mention the lot size quantity as 10 and the system
will create 6 different planned orders.
Now for case2: the only possible solution will be create a copy of fixed lot size and include the check box for last lot exact in
OMI4 for this particular lot size,so that the system create 5 planned orders for 10 quantity each by mentioning the fixed lot size
quantity as 10 and the last planned order alone will be for 4 quantity.
Check and revert back.

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.

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

Lot sizes in CTM

I'm tring to use fixed lot sizes (or rounding values or min max lot sizes) for raw materials in CTM. But my CTM don't take them into account at all. Lot sizes are specified both at source and destination location products.
In CTM profile
Lot Size = "0 Use"
Lot Size for stock Transfers - tried all 3 variants - the result is the same
What can be wrong?

Hi,
CTM uses all lot sizes in the location product master except the periodic lot size and the reorder point method. However, CTM uses the lot sizes only for the main output product and not for input products and co-products. For demands in make-to-order production, CTM does not consider lot sizes.
If you are checking it at input product it doesnt work.

Generating alerts in Purchase Requisition = 3*Lot size of material

Hi Experts,
We want to create alerts in SNP.
Below is the condition.
Heuristics for multiple product-location will run in background.
After the Purchase Requisitions are created, we want to compare the quantity of created purchase requisition at each time bucket with lot size maintained for that product-location.
Alert should get generated if the PR qty is >= 3*lot size of that product-location.
is there any user exist or function module avaialble to call the tabel which contains rounding profile/lot size details in APO?
Thanks for looking at it,,
Rgds/
Jay

Jayprakash,
You can extract the Lot Size values using the macro function MATLOC()
MATLOC( 'FIELD_NAME' ; <'product'> ; <'location'> ; <'version'> ) returns the content of a numerical field in the location/product master record of the specified product and location. The arguments for product, location, and version are optional. If you do not specify an argument for the product and/or location, the system uses the current product/location. However, it is better for performance reasons to use the functions ACT_LOCATION and ACT_PRODUCT. For example, MATLOC( 'BSTMA' ; ACT_PRODUCT ; ACT_LOCATION ) returns the maximum lot size for this location product.
In your case you can use:
MATLOC( 'BSTFE' ; ACT_PRODUCT ; ACT_LOCATION ), assuming you are using Fixed LOT Size. You can store this value in a layout variable 'V' and raise alerts based on condition:
IF ( KF for PREQ > 3 * Layout Variable V) RAISE Alert
Hope this helps
Cheers!

Lot size EX with Minimum lot size

Hi all,
I have a query like how will the material behave if the following settings are made
MRP type:M0
Lot size:EX
Minimum lot size:100
Rounding value:100
Maximum lot size:300
My main question is is it right to use lot size EX along with mimium lot size value,rounding value,Maximum lot size defined.

Hi Anshul
Ex is lot for lot order quqntity. It will put lot size exactly what is required from MRP run. During MRP run after net requirement calculation the system will look for Lot size,Rounding value and Rounding profile before making procurement proposal.
You can use EX with Rounding value
If you requirement is 180 Nos and the rounding vaule is 100 the lot size for this will be 200.
Hope this will clear your doubt.
Regards

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,
Vikas

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

Lot size dependent / independent

Hi, please advise when the system uses this lot size times data in mrp4 view? Where we need to specify that whether lot size dependent or independent need to select? When the system uses this data and when the system uses the planned delivery days and in-house production days which is in mrp2? Pls advise.

Dear,
Planned Delivery Time use for external procurement Like raw materials.
In-house production time use for in house manufacture materials like HELB and FERT.
In-house production time is independent of the order quantity.
Lot size depnendent timing calculate from the routing. It is calculated byadding the lead times of all operations, the float before production, and the float after production.
You schedule the routing for a base qty The in the scheduling results screen click the button" scheduling results"
You will get the results screen in days.
In that screen at the botton there is abutton update material master.
After this go to CA96 There update the material master.
Please refer this link,

Lot size Key without splitting Quota

Hi,
Can any one explain me what is the use of Lot size Key without splitting Quota.
We had created a lot size Key - XY with following seting:-
1) Lotsize Proceed = P
2) Lotsize indicator -K
3) Scheduling =2
4) No of periods = 1
5) Splitting Quota = Not checked(blank)
If we had configured this lot size key, what is the benefits of the above setting, What testing need to be done to know whether this lot size key is working perfectly after configuration?.
Thanks in advance

Hi,
If splitting quota indicator not set, then qouta arrangement is not used during planning wrt to selected lot size.
Lot size procedure you selected, it is a periodic lot sizing procedure. Here the system groups several requirements within a time interval together to form a lot.
Lot size indicator Determines how the lot size is calculated for a certain lot-sizing procedure during material requirements planning. For your selection system creates lot size by refereing to planning calender defined in the system
Scheduling -
This indicator defines the time in the period the system is to create the availability date or the start date for the lot for period
lot-sizing procedures.
The availability date is the date on which the material, including the goods receipt processing time, is available again. In the MRP list, the availability date is equal to the MRP date.
In in-house production, the start date is the order start date, in external procurement the start date is the release date.
according to your selection - Availability date at period end
No of periods - 1
Run a complete MRP cycel to check whether it is working properly or not.
Post the results what you get.

Pavan

MRP Lot Size Difference

Hi All
In OMI4 ie. MRP lot size procedure i see several MRP lot sizes i.e. EX, WB etc....
But only major difference i find is in terms of scheduling i.e.
Blank (Requirement date = delivery date), 1 (period start = delivery date), & so on i.e. 2, 3, 4
Can anyone tell how it works?????? What is its significance
Example would be very good for me
Please suggest
Rgds

Hi Vicky,
Requirement date = delivery date
Planning or procurement proposal will create on req date
Period start = Delivery date
Planning or procurement proposal will create on period start.
ie, if you use period lot size WB,MB.
WB means weekly lot size ie, on Monday cumulated requirement will create for that week. Same for MB, month end planning proposal will create.
Period End = Delivery date
ie, if you use period lot size WB,MB.
On Saturday cumulated requirement will create for that week if you use WB. Same for MB.
This concept will not work if you use planning time fence.
