Logic flow of SAP BW transformations

Sunny morning to everybody,

Is there any way to present a complex transformation logic in BW?

There is a multi step transformation that I want to make transparent to business users. The best way to debug through data flow thats is too technical. Power point/visio are not linked with actual system.

I want to build a transparent front end that pulls out the existing logic and shows the entire transformation process (from source data up to numbers in the report)

Thanks
