Hi Mounika,

I saw your comment on one pdn article for calling a pagelist inside a pagelist,

[How to use IsInPageList function in which pagelist contains another pagelist | Support Center (pega.com)](https://support.pega.com/question/how-use-isinpagelist-function-which-pagelist-contains-another-pagelist)

Did you got any solution for this.

Thanks in advance.

@AbhishekPabitwar

we cannot use this function directly. Since you want to check the logic inside when only, you can take below mentioned approach:

Create a DataPage of type page. (Use some property (say ValueExist) which will return true if value exist in the embedded pagelist else, false) - Use this data page in the when rule

Use a DT as a source. In DT

1. set ValueExist as false

2. For Each Page In -to loop over first Page list

2.1 when IsInPageList(PropertyValue,Property,PageList2).

2.1.1Set ValueExist to true

- You can also parameterize the property values to make it reusable
