Running TS optimizer on monthly bucket

[ayanbishnu1981]

Hello All

I am planning to create a scenerio for simulation planning where in I want to run TS optimiser on a monthly level. My objective is even to have the data saved at monthly level only. Since I am copying the the standard planning area so all standard KF for optimizer are a technical week level. So below is what i am doing

1) Doing an advance copy of the PA and change the time profile where month is the most detailed level. Will change storage level to month in the planning area.

2) Creating new planning levels that have months as root in the planning level. Basically copying existing planning levels iof technical week and changing them to monthly level.

3) I will change the base PL of all the standard input and output KF of the optimizer from technical week to monthly planning level.

4) Configure TS optimizer to run on a monthly bucket.

My question is will the above steps be sufficient to make sure that optimiser runs at monthly level and save data at monthly level ? or am I missing something ?

Feedbacks and inputs please.

Hello Ayan,

you also need to adapt the leadtimes, as they are maintained in number of periods.

Another option is time aggregation - then you don't have to adapt anything. If the results are satisfying for your use case, you can you can switch to a monthly based planning area later.

Kind regards, Carsten

Hello Carsten

Thanks a lot for your prompt reply. I know about the time aggregation profiles. Before i use that I have a query. If i use time aggregation then the optimizer will run at a monthly level. But still the KFs for production receipts are at technical weeks. Since optimizer cannot run on technical weeks it will only consider cal week and will save the data in technical weeks as this is my Base PL. Now say i am on cal week that has 5 days in technical week 1 and 2 days in technical week2. so if a production plan of 100 is generated by the optimizer for that cal week how will this data be splitted in technical weeks ? will it just split 50 and 50 on tech week 1 and tech week 2? I think it will do so or will it split the value of 100 proportionately between tech week1 and tech week 2 based on the no of days available in that particular technical weeks ?

When the optimizer runs on technical weeks and aggregates to months, all productions/transports will start and end on the first technical week of a month (everything is aggregated to the first technical week of a month). There will be no split to the other technical weeks. If it is run on calendar weeks a disaggregation into the possible 2 technical weeks will happen.

Hello all,

What is use of having the time profile level in the S&OP operator profile either it could be heuristic or optimizer?

1. Initially my understanding was, we can run operator at levels specified in the profile. is my understanding correct? if yes, any aggregation or disaggregation needs to be handled before we set the levels?

2. operators contain week as time profile level, should we consider it as technical week or Calendar week?

Thanks alot!!!

Revan

Hello Revan,

yes, you can run the operator on the time level specified in the profile. But it makes usually only sense to run it on the time level for which the master data and key-figures are setup. Otherwise for example leadtimes or lot-sizes will not be suitable, since they aren't adapted to the selected time level. Therefore it is usually recommended to run on calendar weeks and not on technical weeks.

Kind regards, Carsten
