How can we remove certain page from a pagelist embedded inside another pagelist?
In order to remove page from a pagelist based on a condition we can set pyDeletedObject to true on pages that need to be removed, and then use the function RemoveDeletedObjects to remove the required pages but the requirement is to remove some page in the embedded pagelist and when I am trying to use RemoveDeletedObjects inside the first loop, it is throwing error. How can we achieve this? Is there any other approach?

While the loop is running you cannot delete any embedded page because Pega will loose the index sequence in the loop. You need to store the index of the embedded page in a parameter while the loop is running, suppose by using @IndexInPageList(), which you want to remove. After the loop ends you can directly do a page-remove and pass the embedded page along with the index eg: <pagelistname.embeddedpage(Param.Index)>

@SohamM95 but I want to achieve this through a pre data transform in a flow action and there can be multiple pages which can be removed based on some condition.

You cannot remove any page while the loop is running. You can try this process, set pyDeletedObject to true on the embedded page while the loop is running. Then run a job to to delete those records using RemoveDeletedObjects or some other logic. But I think the same error will pop up.

@Sakshi Maheshwari you can use a temp pagelist. Loop the embedded pagelist, for logic= true, copy it to temp pagelist. Now remove embedded pagelist and again append temppagelist to your embedded pagelist.

Could you invoke RemoveDeletedObjects after the loop? The screenshot would help understand the problem
