upper limits

[Former Member]

Hi all

I´m trying to run a SNP optmization, but for the first bucket period stock transfer, purchase requisition and production planned are not allowed

I´m using a time bucket profile of 3 months with 2 months display in weeks. I have a demand of 1000ST for the first bucket (first week) and the tool is suppose to plan production orders for this first period because the stock on hand in this location is bellow the demand (stock on hand < demand)

The tool is showing the followed message:

Production process model PPM_10008_1160 cannot be executed from bucket 20090831->20090906 to bucket 20090831->20090906 because the upper limit for the number of executable lots was set to 0.

How can i fix this in order to SNP optmization start planning production orders, stock transfer and purchase requisition from the first period.

For example: time needed to produce this order is less then 1 day, the planned delivery time to procure is les than 2 days (there are enought stock for the first period to use for the PPM). and the time to transport the good is 8 Hours.

Hi David,

I hope you are well.

I guess you checked the production and stock transfer hosrizon in the product master...

Do you use cross-period lot size planning?

Could you also try the following: set your planning book to start one week in the past (you can define a lag in the planning book) and try again... Do you have the same result?

Thanks and Regards

Hi Julien

Yes, I checked the production and stock transfer horizon in the product master for this product and it is set with 0 (for both). What should be the value fro this horizon?

I also tried using cross-period lot size planning, but i don´t know if this apply to our case, because i´m not using setup operation. and o set the planning book to start one week in the past, but i´m getting the same result from the optimization run

where can I set active production horizon?

Hi David,

I would actually suggerst NOT to use cross-period lot size.

Also try a simple lot for lot to start with and see what it give.

If you are using bound profile (S_AP9_75000249) try to remove them too..

Sorry I can't help more...

Let me know how you manage!

Hi

I tried everything, but still I can´t plan order for the first bucket. I´m not using cross-period lot size or bound profile.

I set my planning book to start one week in the past, but this does not work. I´m receving the same message in the optimizer log.

The tool is showing the followed message:

Production process model PPM_10008_1160 cannot be executed from bucket 20090831->20090906 to bucket 20090831->20090906 because the upper limit for the number of executable lots was set to 0.

Please someone tell me where can i change the upper limit for the number of executable lots.

Thanks!!

David
