Reverse Sign Property of EPM Addins

Hi,

We need to flip the sign of data in BPC using the Sheet Options flag "Use Reverse sign Property". As per EPM user guide, it suggests to be used with BW reverse sign property. We have not found anything on BW for setting up reverse sign. And if its true, we would also like to know if changes in BW, has any impact on database.

Looking for solution on how to make reverse sign work.

Thanks in advance for help.
