Hey,

Campaign management design requires that a parent campaign can have "campaign items" child records, and child campaigns should not, instead, their layouts will display the parent's campaign items records.

I am trying to apply this via Lightning App Builder; I put a "related list" standard component, select "parent campaign" record, and select "campaign items" related list. However, I can't seem to display any related list of parent campaign. Whatever related list of parent campaign I set to, I get this text instead: "We can't display this information because the record has no parent or you don’t have access. Ask your admin for help.".



Below screenshot is the Lightning Page of above layout. You can see the parent's campaign items related list detail:

 

I am definitely sure that I have campaign items related list placed on the standard layouts on both child record type and parent record type. And the child campaign I view has its "ParentId" field populated. There can't be any visibility / permission issue since my profile is System Administrator.

In Lightning App Builder, I do several experiments such as changing the parent record on related list component, and everything except for parent campaign, the related list displays normally. This issue is exclusive to parent campaign.

I couldn't find anything related to this issue on boards and Salesforce pages. Anyone else have experienced this? This is becoming frustrating for me.

Regards,
Tolga
