@PhuP16948644 Hey, I’ve also struggled to find detailed docs on pega.desktop.openAssignment. From what I’ve seen, the first argument is definitely the assignment key, like you said. The others seem related to content containers and some config flags, but it’s pretty vague. The function code shows handling for things like contentID, dynamicContainerID, and a flag for skipping conflict checks, but the exact purpose of each isn’t clearly documented anywhere. If anyone has official details or has experimented with these parameters, I’d love to hear more. Meanwhile, I’d suggest trying to pass empty strings or nulls for unused args and see what changes in behavior

The function pega.desktop.openAssignment is used to open an assignment from JavaScript in older Pega UI (not in Constellation). It takes 7 arguments. The first one is the assignment key (like case ID). The second is the content ID, used to open in a specific tab. The third is the dynamic container ID, used to decide where the screen should open. The fourth is sometimes used for callback or additional instructions. The fifth is a flag to skip conflict check (use “true” to allow opening same case in multiple tabs). The sixth is mostly internal and repeats the key or SafeURL. The seventh is an optional object for passing extra parameters. Most of the time, only the first and fifth are commonly used.
