I have gone through different blogs on when and why to use private version of SAC. We are exploring the option as, we are checking SAC as standalone Planning solution on top of S4.
Plan is to work with SAP sales executive and negotiate on the pricing. But before that we want to know what are different variants of Private SAC under offering.
Please share any note or article explaining the same. It will help us set expectation before actual meeting with SAP Sales.
