Introduction:
In Dynamics 365 CRM, for certain requirements we need to delete records in tables. As an example, for a selected contact record ,record gets deleted.
Step 1:
Login to the required environment and select required solution [Contact Customizations Solution in this case] as shown in the below figure.

Step 2:
After Step 1, select contact web resource in solution and click on Edit as shown in the below figure.

Step 3:
After Step 2, we prepare a contactGUID for a selected contact record with the below code
let contactGUID=Xrm.Page.data.entity.getId().replace(“{“,””).replace(“}”,””);
As shown in the below figure

Step 4:
After Step 3, prepare request to delete record on deleteRecord method of Xrm.WebApi after passing arguments “contact” and guid of contact like below code
Xrm.WebApi.deleteRecord(“contact”, contactGUID).then(
function success(result) {
console.log(“Contact deleted”);
// perform operations on record deletion
},
function (error) {
console.log(error.message);
// handle error conditions
}
);
As shown in the below figure

Step 5:
After Step 4, final code looks like below
if (typeof (ContosoVaccination) == “undefined”)
{
var ContosoVaccination = {__namespace: true};
}
if (typeof (ContosoVaccination.Scripts) == “undefined”)
{
ContosoVaccination.Scripts = {__namespace: true};
}
ContosoVaccination.Scripts.ContactForm =
{
handleOnLoad: function (executionContext)
{
console.log(‘on load – contact form’);
deleteContact(executionContext);
},
__namespace: true
}
function deleteContact(executionContext)
{
let formContext = executionContext.getFormContext();
if (formContext !== null && formContext != ‘undefined’)
{
let contactGUID=Xrm.Page.data.entity.getId().replace(“{“,””).replace(“}”,””);
// delete the record
Xrm.WebApi.deleteRecord(“contact”, contactGUID).then(
function success(result) {
console.log(“Contact deleted”);
// perform operations on record deletion
},
function (error) {
console.log(error.message);
// handle error conditions
}
);
}
}
As shown in the below figure

Step 6:
After Step 5, save Webresource and publish it and register this Webresource in form load event of contact form and publish all the customisations and open a contact record and observe console window that Contact Deleted , and once you observe in the list of contacts, then the selected contact will not be present as shown in the below figure.

Note:
- Make sure to publish all customizations and upload JavaScript (js) file.
- Make sure to provide exact logical name of contact entity and contact table.
- Microsoft documentation can be found here
Conclusion: In this way, one can easily perform delete operation on crm table using XRM Web API deleteRecord method.
