BLs to Export WI to PDF

Hello, 

Is someone aware if the bellow mentioned BLs should still work in 2021x (Cloud) ? I know about RGD + RGR but here it will take to much, I need a simple thing only to export as PDF from WI app with a standard template.

BL1 DELWIDocGen_GeneralCusto.CATRule

BL2 DELWIDocGen_PostProcessOutput.CATRule

BL3 DELWIDocGen_AttachDoc.CATRule

I have tried to do this on the Cloud but Iget the same error like in the BR10000266816 - could not attach document to system.

Fast feedback would be appreciated :) Thanks
