IsInPageListWhen is not able to pick WHEN rule name for each embedded page of another pagelist
IsInPageListWhen is not able to identify WHEN rule name when the function is being used for each embedded page of another pagelist
1. In an Activity rule, one loop is created for each embedded page of pagelist A
2. Under a child step Property-Set,, call IsInPagelistWhen with "lookin" parameter as PageList B and WHEN rule as C created under the pageclass of pagelist B
3. While executing, Pega is not able to find the WHEN rule in Class of B and instead it is trying to search under @baseclass.

Hi @ShashikiranK17312002, Does the class hierarchy is different for all the pagelist?

the when rule C is resolving from the current step page (often @baseclass) instead of the class of items in PageList B. Fix it by setting the right context. First, in Pages & Classes declare B as a Page List with its correct item class, and optionally declare a single page alias like BItem of the same class. In your activity, don’t run IsInPageListWhen from a page of A; pass the page that actually holds B in the lookin parameter (for example pyWorkPage), and reference B by its property name. Use the class-qualified when name, e.g., MyCo-Data-BItem.C, not just C. If resolution still falls back to @baseclass, loop through B(), set the step page to each B(<CURRENT>) and evaluate C with pxEvaluateWhen or a When step; break when true. As another safe pattern, create a wrapper when in the primary class that calls C (applies-to B item class) to anchor rule resolution.
