CRM 9 - Fetch records from a CRM entity based on ID using JavaScript WebResource

Question

I have a entity with multiple records in it. The entity contains 3 fields Parameter Name , Parameter Value , and Contact ID . Contact ID is a lookup field. There are multiple records for a same Contact ID in my CRM Entity.

Now I want to fetch all Parameter Name and Parameter Value from CRM Entity based on the Contact ID .

I am using following code,

var Query = "$select=vrp_parametername&$filter= vrp_contactid eq '" + contactid + "'";
 XrmSvcToolkit.retrieveMultiple({
    entityName: entity ,  
    odataQuery: Query,
    async: false,
    successCallback: successCallback,
    errorCallback: errorCallback
});

But I am getting following error,

Error has occurred in retrieving Response - Error: 400: Bad Request: No property 'vrp_contactid' exists in type 'Microsoft.Xrm.Sdk.Entity' at position 1

Answer 1

Error clearly states that for that particular entity it could not find vrp_contactid field. Why don't you check if field is available. Try using Crm restbuilder and see which condition attribute is available.

Answer 2

You should use _vrp_contactid_value

var Query = "$select=vrp_parametername&$filter=_vrp_contactid_value eq '" + contactid + "'";

Update :

You can use the filter using single valued navigation property, refer my blog on same topic. There is another version of this query below:

var Query = "$select=vrp_parametername&$filter=vrp_contactid/contactid eq '" + contactid + "'";

Answer 3

I was mixing the Schema Name with Logical Name in CRM in this case. I was using Schema Name in CRM which was why this error was coming.

What I did was simply used the Logical Name in this case and was able to achieved the desired result.

Thank you all for the help
