(0) ShareShare

Posted on by Nida_Sayedi 90

I have a dataverse table  CnbTable with Columns Place (lookup column) and CnBOfficer(Lookup Column),

I have another table AssignCNB with columns Year , Location (lookup) , CnBUser(Text feild), I  have to create a form in my model driven app where if I select Location as Bangalore it should auto populate CnBOfficer of that place  in CnbUserText Field .

 

How do I achieve this in a model driven app

    To achieve that, you need to write JavaScript on the AssignCNB form.

    The script should trigger onChange of the Location (lookup) fields and if it contains data, 

    • Xrm.WebApi.retrieveMultipleRecords call to CnbTable 
      • $filter <<Place>> eq <<GUID of Location>>
      • $expand <<CnBOfficer>> ($select=<<Name Column>>)
    • Take the data from the first array object and populate it to the CnBUser(Text feild)
