Hi,
We are working with 1 production plant and 5 DCs.We are using SNP optimisation as storage capacity is a constraint to us in the business.SNP optimiser is not respecting the storage capacity as hard constraint. In the results log,we are getting a clear warning message that Storage capacity is not available but this a warning message and creating planned orders. As per the help documentation,it is written that it is a soft consraint.Expectation is that optimiser should check the capacity and stop creating the order for the balance quantity. i maintaines high storage capacity costs in the storage resource like 999999...but still we are getting excess orders with the warning messages.
Could anybody explain whether any settings are to be done or it is only a soft constraint?? i tried with both linear and discrete...but getting same results.
Thanks in Advance

Hi Akhtar,
We hav'nt heard from you for long, is your issue resolved ?
Thanks,

Hi Aktar,
Please let me understand your problem. You want to say that Planned orders are created even if there is no space in the Plant??? is it what you are trying to say.
Storage capacity and Work Centre capacity are two different things. When Planned orders are created by the Optimizer run it looks into the machine Capacity, irrespective of the high cost, Optimizer will never drop a demand if it finds that capacity is available on the machine. The costs of 99999... etc. is per Base unit will not help.
If you need to ristrict Optimizer from planning because of the space constraint in the Plant then you need to define each Storage capacity as a resource with the capacity in APO and attach it to the Plant.
Please be more clear on what is your requirement, then probably a solution can be suggested.
Thanks,
Harsh

Hi Aktar,
In addition to that what Suresh has mentioned already, I would like to say, that please check the storage cost again, and compare it with other cost. The cost you maintain as storage cost, it is per product. And in your storage resource, 1 unit of resource consumption may contain 1000 or 2000.. or more no. of products (please check you have maintained 'Storage Cons.per BUn' at GR/GI tab of product master. So, per unit resource consumption incure mich bigger amount of cost. So, optimizer will not plan for any product if you not maintain much higher (as compre to strg cost) non delivery penalty cost. Because the main aim of the optimizer is to minimize the cost only.
So, putting high storage cost does not make sense when you have to put higher non delivery penalty cost.
Thanks,

Hello Aktar
I think you might have not defined the storage capacity consumption.Can you review if this is the case,by checking the consumption data in snp capacity view?As you are getting the message "Storage capacity is not available ",perhaps the definition of storage capacity/master data need to be reviewed
Regards
Suresh
