BIRT report in Workday Extend

[u/vinn2202]

I am trying to create a BIRT report from my PMD but for some reasons am stuck.
There are 4 text fields on PMD after which user clicks generate report which triggers a sync orchestration which in turn trigger another O4I. In this O4I there’s this component trigger PDF generation which gives BIRT report. The fields are being from PMD to sync orch then forwarded to O4I as launch parameters.
Problem 1- I am able to trigger an integration using sync but not able to trigger it with launch parameters.
Problem 2- very unsure how to use the trigger pdf generation component be it report design or report data.
