I have created a Flow dimension to track the cash flow movements. Under TotalFlows, I have the different movements (OpBalance, CloBalance, Variation, Gain, Loss), all with aggregation weight of 1. But I have to create an additional structure (sibling of TotalFlows), called TotalFlows2, with shared members (OpBalance, CloBalance...) but with aggregation weight of zero.
Can I used the Shared Member with different aggregation weight? Or should I rename them (for ex., TF2_OpBalance)?
Absolutely use the shared member and set the aggregation weight to zero in your duplicate structure, this is the key benefit to custom dimensions.
