SNP Discrete Opt .... Lot Size is not correct

Dear Experts ,
I need some help with SNP Optimization execution ...... Actually i am executing discrete optimization , using weekly buckets.
For i.e
I have a demand with 100 pc ..... minimum lot size is 60 and max lot size is 62 .....
SNP should create two lots with 60 pc each one , but it is creating one lot with 60 and a second lot with 40 ..... It is considering last lot exact to fulfill demand .....
All PDS have discretization flag and the relevant parameters for discretization are set on OPT profile .....
I some setting missing ?
Please i need some help asap .....
Kind Regards
Mauricio

Dear Nandhu ,
Thanks for you help.
At OPT Profile , Discret Constraints tab at Minimun PDS Lot Size and Integral PDS i am maintaining 90 D ..... and when i execute the optmizer i am using 60 days . The Planning Book Horizons is 3 months in weekly buckets.
Kind Regards
Mauricio

Problem on Mac OS [ColorSync/Profiles/EW-sRGB Tag 'desc': Tag size is not correct. Could not be fixed.]

Problem on Mac OS [ColorSync//Profiles/EW-sRGB
Tag 'desc': Tag size is not correct. Could not be fixed.]
My screen contrast has gone awry and the ColorSync Utility is unable to fix the problem. In searching the wisdom of the web, I found a response from 2009 on another forum, which referenced this forum. But the thread is gone. The information was in regard to the Color Profiler. Can anyone help? Has anyone had to deal with this? I found a lot of people looking to fix this, but not a lot of follow-up replies with answers. I have tried reinstalling the file from a back-up and re-booting, but to no avail. Some have suggested a problem with the Epson software. But without any detail, I don't know what to look to change. Any help, advice, cures, etc. would be greatly appreciated. Thanks!

Sorry, I thought you asked what course of action to take.
It means the data for that "tag" in the profile is not the size expected - I know, that's obvious too. The 'dmnd' tag contains the manufacturer's description.

[Photoshop CS5] Optimize to File Size working not correctly.

******BUG******
Concise problem statement: Optimize to File Size working not correctly.
Steps to reproduce bug:
1. Open any photo.
2. Draw a slice
3. Save For Web, choose Optimize to File Size, type 10KB (Current Slice).
4. Save "selected slices" only
Results: File result larger than expect (over 10KB)
Expected results: <=10KB filesize.
I uninstalled whole Adobe CS5 Master Collection (Trial) & tried to reproduce the bug in Photoshop CS4, but it was not happened, it's ok on CS4.
Finally, Windows 7 is not reason, it's a bug of Photoshop CS5. Please fix, I don't want to buy a bugged software.
I really need the feature "Optimize to File Size" in my works.
P.S: I tested on 4 PCs, and the results is the same.

In the SFW dialog change the Metadata dropdown to None

Tag 'dmnd': Tag size is not correct msg in Colorsync Utility

When I press the verify button in the Colorsync Utility, I get the path to my ICC Profile

and then Tag 'dmnd':Tag size is not correct on the next line.
After that, Verify done - found 1 bad profile.
The printer works ok in Photoshop, though prints maybe come out a bit on the dark side as compared to my calibrated screen.
Is this something to be concerened about, and if so, what exactly is the course of action I should take?
Thanks

Pass on lot size" function not supported in costing runs

hi when i am doing cost estimate through ck40n i am getting following error.
Pass on lot size" function not supported in costing runs
Message no. CK463
Diagnosis
You have selected costing variant PPC1 for the costing run. The Pass on lot size indicator is set in this costing variant. Costing variants in which this indicator is set cannot be used by the costing run.
System Response
The costing run is not created.
Procedure
You have the following options:
Reset the Pass on lot size indicator in costing variant PPC1 so that the lot size is not passed on.
Use a different costing variant in which the Pass on lot size indicator is not set.
if any one had found any same king of error please help me in fix it.
thanks
kareem

Probably this might be the cause
Sales order by Costing
Check out the below
Pass On Lot Size
Definition
If this indicator is selected, the system determines the costing lot size using the lot size of the highest material in the BOM and the input quantities of the components.
Use
1) Do not pass on lot size
If this indicator is not selected, the materials further down in the structure are costed in accordance with the lot size in the costing view of the material master record. When the materials in the next-highest costing level are costed, the costing results of the semifinished materials are converted to the lot size of the finished material to calculate the material costs for the finished product.
2) Pass on lot size only with individual requirement
In the MRP view of the material master record, you can specify that a material is planned as an individual requirement. If such a material is added to another material, costing uses the lot size of the highest material.
3) Always pass on lot size
Here, the costs for all the materials in a multi-level BOM are calculated using the costing lot size of the highest material. This function is used principally in sales order costing.
If you are costing sales orders using product costing for a material with a multilevel BOM that is produced in-house, choose 2) or 3) . For those individual requirements materials, from a business management point of view it is recommended that the order lot size be used when costing the material components going into the finished product. On the other hand, materials subject to collective requirements are generally costed using the costing lot size in the material master record.
Thanks

SNP Heursitic run - Lot size of Purchase Requisitions

Hi,
when we run network Heuristics we get Preqs with decimals. As far as I can see we have maintained the lot size correctly and even the rounding value. Still I get Preqs with 0,054 EA, but I'm expecting to get 1 EA.
Has anyone experienced something similar?
Thanks,
Lars

Thanks for your help, Aparna.
Seems like I forgot to specify that the issue was related to the PReqs in R/3, created by the Heuristic run in APO.
However, I think we found the problem. The rounding value from Material Master was not CIF'ed over til APO. When we maintained the rounding value manually in the product master in APO we got the result we wanted.
Thanks!
Lars

Material set to lot size TB not summing up orders when covering

Hello all. I'd appreciate any input on this problem we're seeing.
We have a material that has lot size set to "TB" (Daily lot size). This leads us to expect that demands on this material will be covered by purchase orders summing up all the demands for this day.
For instance we currently have 10 orders for 11. sep in different quantities from 1 to 3. Since the material is set to lot size TB we would expect to see a purchase order for 19 pieces which is the total.
But instead we get a bunch of small purchase orders, the system doesn't appear to sum up as expected.
Has anyone any ideas about why this may be so?
Regards
Simon Pedersen

Thanks for the answers so far, It's not letting us make much progress though.
The material is a trading good (HAWA). It has no BOM. The Collective indicator on MRP4 is not maintained (as far as i know it should not be since there are no dependent requirements involved). The demand is triggered by Sales Orders.
The purchase requisitions get generated by the MRP run based on these sales orders. That is what we don't understand, since the material is set to TB the MRP should make a single bigger order instead of many small ones.

Periodic lot size PR not covering the requirement for the periods

Dear Experts,
I am using customized monthly lot size size key with Periodic lot size procedure and number of periods 3 months.
The MRP is creating one purchase requisitions for all the requirements for the first month only. The second and third month requirements are not included for the purchase requisition quantity. The second and third month requirements are kept opened without any PR.
The planning harizon is 100 days which is more than 3 months. There is no maximum lot size restrictions. But still why the purchase requisition quantity is not included the second and third month requirements.
Please give your valuable suggestions.
thanks and regards
Muru

Well, to start off with:
Your title on your post has nothing to do with what you are asking in your question,
2nd-your question does not reflect what you ask in your title
Try printing the results out to your console: System.out.println(), I believe you'll find your calls do not return anything to show.
Use your debugger to trace through your project to visually see and find what is happening.
BTW: if you want to fix the displayed size problem with your JFrame: make a JPanel and setPerferredSize to what you want add it to your JFrame and then add all of your other GUI components to your JPanel. When you pack your JFrame, it will take the size of your JPanel.

Font Size is not correct in the exported PDF-File

In the Report is the Font Arial Size 8, but in the exported PDF-Fildethe size is only 7,15. The Fontsize in the PDF-File is always smaller then in the Report.
I use Crystal Report XI. With Version 9 is everythink ok.

In Crystal Reports 10 and 11, exported fonts are shrunk by 5% to avoid field truncation.
For version 11, create the following registry entry and then set the value to 1 to maintain the font size:
HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\Export\PDF\ForceLargerFonts
Please back-up your registry before editing.

CK727 -Lot size cannot be passed on in combination with mixed costing

I get below error.
We have KMAT materials and scenario is Non Valuated Sales Order Stock.
in our PPC4 - we have below settings. (Both are SAP recommended)
Qty Structure tab we have Pass on Lot size "1" with individual requirements (must of Non Valuated Sales) and
Transfer Control "PC03" has "Current Std Cost" with "Transfer only with Collective requirements"
I just created a mixed cost qty structure. In it I even added Costing type "01". Sales order costing type is "18".
Mixed costing works as expected. However we are unable to create any Sales Orders.
Lot size cannot be passed on in combination with mixed costing
Message no. CK727
Diagnosis
For costing variant PPC4 and costing version 01, it was defined in Customizing that a mixed cost estimate should be created for quantity structure category M0001. At the same time, it was defined in the costing variant that the Pass_on_lot_size function should be active.
System Response
Mixed costing cannot be carried out simultaneously with Pass on lot size . Costing cannot be proceeded with.
Any help is appreciated.

Hi Kala,
system's response is correct
In the standard program the combination of mixed costing and
simultaneously pass on lot size is not possible.
Please review SAP Notes 402440, 584420 and 749128 .
In particular the SAP Note 402440 describes the determination of the
costing lot size at a mixed costing in detail.

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

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

MRP lot size?

HI All,
Guys i configured M.R.P Type and M.R.P Controller, but I am unable to understand the M.R.P Lot size?
while i am creating a material in mm01 lot size is not allowing me to chose any other option except EX-Lot for Lot Order quantity.. could any one suggest why is it so..?
Thanks and Regards,
Chinta

> while i am creating a material in mm01 lot size is not allowing me to chose any other option except EX-Lot for Lot Order quantity.. could any one suggest why is it so..?
Do you mean you can see all the lot sizes but system is not allowing to select or you can see only EX? Because only "EX" lot size doesnt require further data. But if you select any other lot sizes like "FX - fixed lot", you also need to enter the fixed lot size value in fixed value. if you are dealing with CBP, below are the important lot sized to use.
Lot-for-Lot Order Quantity
Fixed Lot Size
Replenishment up to Maximum Stock Level

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
