Extracting from PSA for reporting, is this Reasonable?

Is it normal (or reasonable) for a process, that is using BW to get it data, to do the extract from the PSA instead of the ODS or InfoCube?

I am not that familiar with BW, so I am learning this as I go.

We decided that it was a good idea to leverage an existing extract, and remove the filter from the extract, but then implement the filter (needed by only one process) between the PSA and the ODS.

Both processes would share the PSA area and the extract.

Each process would have its own ODS.

Today I was told that the existing process was extracting its data from the PSA area, for its report.

Is this even reasonable. 

Why would a process want to extract from the PSA area instead of the ODS or InfoCube?

Is there any advantage to this?

Dear Eileen

Its not at all advisable to report from a PSA table when you have the ODS and cube which is only meant for reporting.

I think you have talk to them and have a better clarity as extracting from PSA has another meaning , it can be PSA data getting loaded into the ODS or Cube.
