I've searched quite a bit and have no idea where to go about searching for documentation that clearly outlines the parameter definitions and the accepted text input values (e.g. calendar).Would appreciate any advise around this.

The 'Parameter' tab provides information about the parameters and 'History' tab gives details about the function. Also, "Standard Function Rules" in 'Pega help', gives us the function information. Hope this helps!!

Does below link help at your end? https://pdn.pega.com/community/pega-product-support/question/populate-business-day-based-calendar Regards, Rincy Posted: 3 years agoHabeebBaig PEGA replied to HimanshuJ8958For OOTB api's you can check under resources section on you designer studio top right corner. Also for OOTB rules sometimes the documentation tab gives you the exact information you need.
