1. Where can find a document about How planning of costs and for project works in SAC
2. For the Plan/Actual: Each will be explored as categories can i have more than one category in the model?
Also, the planned cost values have a different FEX than the IS-values how can that be maintained in SAC . I know that i can define the preferences for each model( like currency and currency conversion) does that mean i have to create a model for each planned and cost then use more than one model in my story?
