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:

1. Make sure to publish all customizations and upload JavaScript (js) file.
2. Make sure to provide exact logical name of contact entity and contact table.
3. 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.
