Yesterday I wrote about our trouble defining policies when you can't figure out what planning strategy ZY does.

Today I find myself in Capacity Planning, Scheduling and Costing and a similar, frustrating meeting is taking place: For some reason the available capacity, the capacity load from the orders and the cost calculated for actual activities did not make sense.

In the capacity screen it was defined that 2 capacities are available from 8 am to 5pm with 1 hour break every workday. Therefore the available capacity was 16 hours per day. But in CM01 the available capacity showed 32 hours every day?!

Similar things were going on with the capacity load and the cost. It just didn't make sense.

As we tried to get to the bottom of it, we realized that, during the implementation it was decided to not use the formulas provided in standsrd SAP but to use Z formulas. Everywhere we looked at, there was a customized formula starting with a Z. As we checked these formulas, which was a very time consuming effort, we found many, many errors.

Long story, short answer: we had to reconfigure every resource and used the standard value keys and formulas. And of course it worked and the expected results came showing... But that was a hell of an effort!

My question is: Why would anyone NOT use the standard formula to calculate available capacity? Is the available capacity really different in your company as it is in another? Or did you get infected with the deZse that so many SAP customers suffer from?
