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.

IN View ProfileSend MessagePranathiC PEGA replied to HimanshuJ8958Open the function in designer studio. It will give us help about the function. 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!! Posted: 3 years agoPosted: 11 Apr 2017 5:17 EDT×Close popoverRincy Rappai (RINCYRAPPAI_GCS) PEGA Technical Lead Pegasystems Inc.

Also for OOTB rules sometimes the documentation tab gives you the exact information you need.
