Populate certain DSO columns by different transformations

Hello experts! I'm really new to bw and ABAP. I've made just simple models that don't require really complex transformations. But I have a requirement from a customer that needs data of different documents on a single view with an status per document generated on a different DSO.

So my question is: Is it possible to create a DSO with "blank" columns and through transformations, call a DSO, populate, store the data, and then on another transformation, call another DSO that compares another part of the date and populate the other column?

Thank you!, best regards
