Reading Many to many relationships in CDS

Hello all. For an app I am building, I require the use of many to many relationships. I am using CDS. I have an entity called "agency" an entity called "tags" and an entity called "tagsmap" that maps tags to agencies and vice versa:

Agency {PrimaryID, name}

tagsmap{PrimaryID, Agency_ (a look up to agency), tag_ (a look up to tags)}

tags{PrimaryID, name}


I want to be able to search for tags and get the names of all agencies that have the tag associated. My process right now looks like this:


1) fitler tags based on a text string and collect the filtered tags

ClearCollect(TempTags, Search(tags, searchbar.text, "name"))

2) filter tagsmap based on the collection of filtered tags

ClearCollect(TMapResults, Filter('tag map', tag_ in TempTags))


This retuns a list of tagsmap entities which have tag entities and agency entities nested within them:

{tagsmap: PrimaryID, Agency_, tag_}

I am stuck here. How do I filter TMapResults in a way that returns agency names?

Hi pz,


Currently, Common Data Service doesn’t support many to many relationship type, please check the documentation at here:


About your scenario, I guess that this thread could be a reference for you:
