Alternating working days and off days Work center capacity in SAP PM/PP

[erickgrilo]

Hi SAP experts

I am currently exploring a scenario in which a work center will work in "DxD" work schedule. This means that it will be available D days 24/7 and the following D days it will be "off" (no work will be performed by this work center). This pattern will then go on. Considering D = 3, the work center will be fully available for three days, then off for three days, and then available 24/7 again for three days. Note that this ignores weekends, holidays and does not depend on the day of the week it is working (i.e, whether it is Monday, Tuesday, etc.).

I thought that this could be achieved by configuring shift sequences in transaction OP4A, in which we define shifts, shift sequences, and shift groupings. So, I have configured an example of shift as follows:

And assigned it to the following sequence:

It seemed that it would work when I assigned it in the work center, but when I go to "intervals and Shifts", this configuration seems to affect only the three first days of the workweek.

If I insert a new interval specifying this shift sequence, the configuration seems to be correctly assigned but only considering weekdays, which does not correspond to the scenario I am trying to model.

Now I'm a bit confused as the shift configuration of a work center does not seem to be the way to obtain this scenario. I was trying to avoid the construction of a specific calendar in transaction SCAL for this scenario as it would require the maintenance of one calendar for each sequence of days: one calendar for 2x2 working/off days, one for 3x3 working/off days, one for 4x4 working days, and so on, but i'm starting to think there is no way around.

Does anyone know the best way to model these work shifts in SAP? Any guidance is greatly appreciated.

Thank you,
