Getting Audit Record Details from Dynamics 365 to Power BI

Question

I have been able to pull down an audit table from Dynamics 365 and load it into Power BI by selecting Get Data, choosing the odata option and using url/api/data/v9.1/audits . I see the column RetrieveAuditDetails , but I don't understand why all the values say Function . Is there a way to extend this to show the old value/new value in the same way you can change, for example, UserIDs to be extended to the full name?

Answer 1

When it comes to audit data, OData/Web API REST endpoint is not so friendly in PowerBI due to the reason that the audit data is stored as delimited values in database. Refer my answer in this SO thread .

If it's a javascript or .net application you can do iterative call using RetrieveAuditDetails function to fetch full details after getting full list using https://crmdev.crm.dynamics.com/api/data/v9.1/audits . This is why you are seeing as Function in there.

For example:

var parameters = {};
var entity = {};
entity.id = "5701259e-59b8-e911-bcd0-00155d0d4a79";
entity.entityType = "audit";
parameters.entity = entity;

var retrieveAuditDetailsRequest = {
    entity: parameters.entity,

    getMetadata: function() {
        return {
            boundParameter: "entity",
            parameterTypes: {
                "entity": {
                    "typeName": "mscrm.audit",
                    "structuralProperty": 5
                }
            },
            operationType: 1,
            operationName: "RetrieveAuditDetails"
        };
    }
};

Xrm.WebApi.online.execute(retrieveAuditDetailsRequest).then(
    function success(result) {
        if (result.ok) {
            var results = JSON.parse(result.responseText);
        }
    },
    function(error) {
        Xrm.Utility.alertDialog(error.message);
    }
);

Update : On further analysis - there is no big difference between the output schema from the above RetrieveAuditDetails query targeting single auditid or the below filtered audits query targeting single recordid .

https://crmdev.crm.dynamics.com/api/data/v9.1/audits?$filter=_objectid_value eq 449d2fd8-58b8-e911-a839-000d3a315cfc

The fact is either web api or fetchxml, the resultset cannot fetch the important column changedata which contains the changed field values - due to the restriction: Retrieve can only return columns that are valid for read. Column : changedata. Entity : audit Retrieve can only return columns that are valid for read. Column : changedata. Entity : audit

I get this in FetchXML builder:

There is another approach but not PowerBI compatible anyway, using RetrieveRecordChangeHistory to target the recordid to get all the audit collections with old & new values. Example below:

https://crmdev.crm.dynamics.com/api/data/v9.0/RetrieveRecordChangeHistory(Target=@Target)?@Target={%22accountid%22:%22449d2fd8-58b8-e911-a839-000d3a315cfc%22,%22@odata.type%22:%22Microsoft.Dynamics.CRM.account%22}
