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.

MRP run with lot size as per prod. version and capacity levelling

Dear PP experts,
Hi, We are working with strategy 10. For SFG and FG produced inhouse we have created BOM and recipe with production version.
For example:
I have a production version with batch size as 100 Kg.
I load PIR for 500 Kg in MD61.
I have maintained lot size as EX in the material master but I have not defined mini. and max. lot size.
Is it possible during the MRP to consider the production version batch size if the mini. and max. lot size is not maintained in the system and create 5 Planned Order of 100 Kg each.
I know, how it can be done by using lot size in material master or by maintaining schedule lines in MD61 or by maintaining quota. But if nothing is maintained is it possible for the system to create 5 Planned orders as per the production version batch size.
Pl. check if this is possible and revert back.
Regards,
Prashant

Hi
No, system will not consider the size that maintained in the production version for the creation of planned order while the mrp run .
This lost size is used to validate the bom/ routing combiation for the particular pv of the material

Maximum lot size - create order manually

Hi Experts,
we are in the implementation phase of the project (PPDS) and need your help.
For the products we have the data of Maximum Lot Size, that is a constrain for the process. But when we execute manual adjustments/creation of the planned orders, this maximum lot size is not respected, because for the manual orders is used the heuristic SAP_PP_001 Change Order Manually.
We need to consider the maximum lot size even for manual adjustments/creation.
Does anyone knows a way to consider the maximum lot size when create orders manually?
Thanks in advance
Thiago Cyrillo

Hi Hans,
If as per the requirement you want the system to take into account the period of 63 days reqirement , then as my experience the lot size field should be changed from the daily lot size .......or else the setting is quite redundant in nature........in accordance to your business requirement.
Check for the period lot sizing for detail information..........incase you have any query then let me know ......
Please reward points if it is helpful.........
Thanks

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

MRP net requirement calcualtion for Lot sizes

Hi all ,
Can some one help me on this ..
I want to set up the MRP for the Raw materials Procurement .
for this i want use MRP type as PD and lot size as WB Weekly lot size .
but as per the requirement the MRP is run daily , i need clarification on certain things such as how does the system calculates the weekly lot size ? say if the requirement is converted into PR on the first day of the MRP run ,followed by that if the requirement varies does the system creates a new PR or it changes the Qty in the existing PR if its was not converted to PO .
what are the stock types considered during PR creation and how are the delivery dates determined during the PR creation ?
thanks ,
ksr

Hi Chris
You can try to set up a maximum lot size and a takt time on the material master.
Take a look on the F1 help of this field on the material master:
Takt time
If a requirement quantity (for example, for capacity reasons) cannot be procured in a single lot, you have to schedule several receipts. In conjunction with the overlap indicator in the lot size (set in Customizing for the lot size), you can use the takt time to specify that these receipts are offset, that is, that they are delayed by the takt time.
You enter the takt time in workdays.
Use
The system uses the takt time if a requirement is covered by several receipt elements due to restrictions on lot size such as maximum lot size (with all lot-sizing procedures) or rounding value (with fixed lot size with splitting).

How to make lot size dependent in Material master?

Hello Experts,
I created a Material master for a Finished product in Pharma industry and in work scheduling screen, under the section "In house production time in days", I see that "lot size independent". What change(s) in my settings in the Material Master can change it to "lot size dependent"?
Does any changes in the "Lot size data" section in the view "MRP1" have any effect on this field?
Also one more question:
Where is the Usage for BOM first specified? Is it in material Master or when creating a BOM?
Thank you.
Message was edited by: Visu Venkat

Hi Visu
No,Lot size data in MRP1 view will not have any effect in inhouse production time in work scheduling view.
You need to maintain the base qty in work scheduling in order to get the scheduling time for lot size dependant.
BOM useage is first specified only during BOM creation.
Suppose if u maintain the BOM useage in material master before creation of BOM, then still u can create a BOM with different useage. During these case, there will be always inconsistencies.
Hence Useage is always specified first during BOM creation.
Hope u r clear now.

Mixed-price variance & Lot size variance

Dears Gurus,
Can anyone give a detail explanation & examples of Mixed-price variance & Lot size variance?
(After reading sap library, I still didn't get clear idea)
Thanks
Ellie

Mixed Price Variance :- This is the variance between a standard price that was calculated in a mixed calculation for more than one procurement alternative and the costing of a procurement alternative.
For Example : Standard Cost was made for a Raw Material A purchased from 2 sources ( X and Y ) with 50/50 ratio..
Actuals it was made of a Raw Material A purchased from X and Y ( in 25:75 ratio ).
The same can happen for production versions also . Standard May have version 1 and 2 (in 50:50 ratio).. actual have version 1 and 2 ( 40: 60) ratio .
Lot Size Variance : Variance due to effect of lot-size-independent costs when the lot size is changed .
For Example : we may have consumables cost per 10000 lot size . Original Lot size during creation of standard is 10000 .
Actually lot size was 150000 .. hence due to change the lot size.. the cost has increased and its lot size variance..
Hope it clarifies..

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?

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.

MRP Type P1 & Lot size PK

Dear All,
This is REM scenario,
Client is going scheduling agreements
material master Settings
MRP Type - P1
Planning time fence - 10
Lot Size - PK
Procurement type - F
GR Processing time - 2 days, No plad delevery time maintained.
in planning calendar we are going with only one day as Friday
and we made previous day is working day if friday is holiday.
After MRP system is proposing dates for schedule lines as
16/06/2010 ( wednesday ) Rescheduling date as 07/06/2010 ( Monday ) ( Rescheduling in i.e 10 )
How system is proposing this dates
Please share your views or if required more info then revert back
i cannot upload Docs as my company policy is not allowing
Regards
Madhu

Hi ,
Bring process forward (reschedule in)
Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
It does not take in to account the GR processing time and it is purely based on the stock requirement date , parameters in Procurement and Scheduling in the Material Master
So it will consume the requirement backward scheduling and bring the Process forward.
Kumar which strategy are you using ? scheduling agreement is of weekly , daily or monthly bucket ?
How many days SA bring to Production and How many days SA for forecast you are doing ?
Are you using any Program to convert these SA in to PIR and upload ( using any program ) .

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

How to perform Data Collection on single SFC with QTY = 1 with material lot size 1?

Dear experts,
We are working with SFC qty>1 on a relaxed routing. At a given operation we want to collect the data on single quantity; i.e. SFC qty on that operation, where the collection will happen, will be 1.The corresponding material lot size is for ex 10. The operator must be able to collect data on SFC with qty=1 multiple times until the quantities will be consumed. He must be also able to collect other values on the remaining quantities on the same operation with the same DC group or other DC groups. How many times the data must be collected is dependent on the shop order build quantity. The data may be collected several time but not more than the build qty. In other words some specific data will be collected on a qty of a product while others will be collected against remaining quantity. The data collection must be also done in a serialized manner.
Here's what we have set up so far:
1) 3 DC groups, each DC group has 3 data fields.
2) Each data field has the following restrictions: Required Data Entries = 0 and Optional Data Entries = 1
3) All DC groups are attached on the same combination of operation\material\routing
4) we are using relaxed routing
Process description:
The operator must be able to collect any data field on single product. For that he will enter the operation where the data collect are attached, he will enter the SFC with qty=1 then he will run the data collection after selecting the appropriate DC Group and entering the needed information. The operator will complete the SFC with qty=1.
The operator will pick the next product, select the same SFC and enter qty 1 and collect other value against this product.
Problem is:
Once the first collection is done on a given SFC with entered qty=1, the system is not allowing the operator to do further collects on the same SFC with qty=1 or any other quantity. He cannot select any DC group from the DC group list. We tried also with the table selection menu on the DC Group list but nothing can be selected.
So we tried to play around with the DC group definitions as follows:
A) we set Required Data Entries = 0 and Optional Data Entries = 10. Still the operator was not able to select any DC group after collecting data the first time. We tried to reopen the pod and list again. But we get the same blocking behavior.
B) we set Required Data Entries = 10 and Optional Data Entries = 1. The operator was able to select the DC group after collecting data the first time. BUT operator must enter the data fields 10 times on one SFC quantity, which is not what we want. Besides again he cannot collect other information on remaining quantities on the same operation.
C) There's an option to serialize the SFC before reaching the operation where the collection is happening, then merging ofter complete. Automation is needed here; hence customization. We are highly avoiding customization now, since we expect the data collect to work well on single quantities even when the main SFC has qty>1
Questions:
1) Are we missing any kind of further configuration\setup?
2) Or the current system design does not allow collecting data on single quantities of an SFC which main quantity is greater than 1?
3) Looking at this link Approaches to Collection of Data - SAP Manufacturing Execution (SAP ME) - SAP Library, there's nothing mentioned about same SFC number with multiple quantities!!!
We are using SAP ME 15.0.3.0.
Thanks in advance for your help
Ali

Ali
to collect data for the same SFC multiple times, your system rule "Allow Multiple Data Collection" needs to be set to true for the site.

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.

MRP run on basis of lot size

Dear all
I have two different lot size routing for a inhouse product are 0-2000 and 0-1500 nos . I planned for 5500 nos , after MRP run system should create planned order as per selection of lot size as 0-2000 for 2 planned order and 0-1500 for 1 planned order .is it possible ?
thans in advanced

siva

Dear,
Quota arrangement can be used if the demand (100) is created in which is define the ratio 60:40 but it will create two planned order after MRP Run. Go to transaction MEQ1 maintain a quota arrangement for this material. In MRP 1 view choose lot size with quota splitting and in MRP 2 view maintain quota usage as 4.

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
