Reopen closed activity in Dynamic 365 Crm

Once an activity is marked as completed in Dynamic 365 CRM, there is no out-of-box way to reopen it.

So here I am outlining a solution that could be used to reopen any close activity. 

It involves us to

1. A Jscript WebResource
2. Creating custom button on specific activity entity

1] Create a Jscript Web resource

function reopenActivity() 

{ 

    var activityName = Xrm.Page.data.entity.getEntityName();

    var activityId = Xrm.Page.data.entity.getId().replace('{', '').replace('}', '');

 

    var entity = {};

    entity.statuscode = 1;

    entity.statecode = 0;

 

    Xrm.WebApi.online.updateRecord(activityName, activityId, entity).then(

        function success(result) {

            var updatedEntityId = result.id;

            Xrm.Page.data.refresh();

        },

        function (error) {

            Xrm.Utility.alertDialog(error.message);

        }

    );

}

3] Create a custom button using Ribbon Workbench

Create a button and define its various parameters.

ID : new.synlims_inspection.ReOpenActivity.Button

Tool Tip Description: Re-Open this Activity to be edited.<br/><br/>The activity moves to the open activity views.

Create a command for button and link the Jscript library created above.

Command ID : new.synlims_inspection.ReOpenActivity.Command

Create a FormStateRule

ID : new.synlims_inspection.ReOpenActivity.EnableRule
