It is a common requirement that end user wants to perform assignments at once, in a bulk operation. In this post, I will share a simple approach how to build such function. Please see attached for the steps.
Activities or handling assignments logic do not have direct connection to UI, and this implementation should work with any of our UI offering (UI-Kit, Theme Cosmos, or Cosmos React). I've also built the same on Theme Cosmos with Pega 8.6 (see below screenshot) and it worked fine.
