"days supply'" exceeding "Maximum Stock Days"

Dear Experts,

Can anyone tell us what are the probable resons for "days supply'" exceeding "Maximum Stock Days" in SAP APO SNP Planning book.

These products are planned on three locations A > B > C.

We see at location C the product's Maximum stock days is not respected.

We checked the Optimizer log and it has given the optimal solution.

Though the Optimizer has planned in this way, we want the Max stock days key figure should be respected.

Please let us know your valuable inputs.

Best Regards,

    Hi Mangesh,

    I don't know any constraints "Maximum Stock Days" for the optimiser...

    Are you using the "storage upper bound" functionality?

    If yes you can based the calculation of a number of days, but need to store the result in a time series key figure in quantity via a macro.

    ensure you key figure is attached to key figure function 5004...

    You shoudl see the value in table ET_LOCPROD under material sotrage capacity I think...

    If you are not please detail your scenario...

    Thanks and Regards

      Hi Mangesh,

      I can tell you can the Storage upper bound functionality can be set up, using standard planning book, but I can't tell you how it was setup in your system... or even if this is the functionality you are using.

      Anyway, the easiest is for you to have a look at setting for standard plannning book / data view 9ATSOPT / OPT_TSBD.

      Here you can see 2 key figures "storage upper bound" and "cost for exceeding the maximum stock level".

      These are times series key figures.

      Have a look at the configuration of the planning book (as mentioned you need to check key figure function) and see if it fit your example...

      Note: analysing the result of the optimiser can be tricky and require a certain level of experience.

      Good luck,
