multiple level of expansion in webapi

(0) ShareShare
ReportReport
Posted on by svignesh 347

I have an entity called as medicalcase

Each medical case has a subgrid, N:N relationship with an entity called as mcfamily

Each mcfamily has Father, Mother, Child fields which are lookups to contact field

Now if I make a webapi call 

http://serverurl/api/data/v8.0/new_medicalcase(caseid)?expand=new_medcase_mcfamily

I get the new_father_value, but I want to expand the Father lookup and get the contact name. How can I do it?

I tried

http://serverurl/api/data/v8.0/new_medicalcase(caseid)?expand=new_medcase_mcfamily($expand=new_father($select=fullname))

But it said 

navigation property can't be expanded. Multiple levels of expansion aren't supported.

    multiple level of expansion in webapi
    Hi @svignesha and @Bipin_D365,
    Note that N:N (many-to-many) relationship are supported with Web API. There's also a nice tool from XrmToolBox to easily manage Web API request especially more complex ones: https://www.xrmtoolbox.com/plugins/GuidoPreite.DRB/
     
    Here's an example of an expand on a N:N relationship: 
    ​​​​​​​$expand=new_gridlayerdimension_entities($select=new_entityid)&$filter=acn_gridlayerentitydimensionid eq 07f55627-fc91-ef11-8a69-6045bd9883e2
    Hope this helps!

    Hi,

    You can only use expand with lookup field. It does not work with N:N relationship.

    To solve your issue you might have to use 2 web api.
