Which resource is being considered in PDS for capacity


we are facing a issue with PDS. when we take SNP optimiser on PPM is gives the plan according to the capacity available as per SNP relevant resource. so when the requirement is greater than the capacity on the resource, optimiser gives unfulfilled demand which we can get from //snpoplog.

but when we take the same optimiser run based on PDS, we do not get any unfulfilled demand. i.e PDS is giving the output which is greater than the capacity of the SNP relevant resource.

we are unable to find out the element in the PDS from which is is considering the capacity for the planning.

moreover when we check the IT_RESOURC in //snpoplog, for PPM it shows both fields rightly - Production capacity use and Production capacity available. But in case of PDS there is only production capacity available, the field production capacity use is having 0 value.

So how would i come to know that what resource capacity is getting considered planning purpose in case of PDS?

we tested case like:

demand to serve : 4,00,000L

Capacity available on SNP relevant resource: 3,60,000L

Planning under PPM: 3,60,000L

planning under PDS: 4,00,000L

when we see pds under pds_maint we confused is two columns : primary resource and Capacity. which field is getting considered for capacity????

can somebody explain this????

    Hi Ashok,

    In APO //CURTO_SIMU, you can see the field "Bucket Resource Consumption (variable)". That's usually the value used in SNP.

    By the way, does the resource have finite scheduling indicator?

    Best regards,

    • Hi Ashok,

      I was showing you a subcontracting one, so both fixed and variable value are filled.

      For a normal one, it's correct that only fixed value exists. It means no matter how much you produce, the capacity consumption is always 1800 seconds.

      So I don't think it has something to do with the PDS itself.

      Best regards,
