In CRM, when you choose ‘Related “Regarding” Records’ option from ‘Activities’ left navigation of Account form, It loads Activities rollup view.

Recently we got a requirement to disable rollup option.
So we used below script to remove the ‘Related “Regarding” Records’ option from “Include” dropdown.
document.getElementById(“navActivities”).onclick = function () {
Mscrm.Details.loadArea(this, “areaActivities”);
document.getElementById(“areaActivitiesFrame”).onreadystatechange = function () {
if (this.readyState == “complete”) {
var doc = this.contentWindow.document;
var filterOn = doc.getElementById(“crmGrid_Account_ActivityPointers_ViewControl”);
filterOn.value = “ImmediateRelatedView”;
filterOn.options.remove(1);
// Refresh the grid
var evt = document.createEvent(“HTMLEvents”);
evt.initEvent(“change”, false, true);
filterOn.dispatchEvent(evt);
}
};
};
How do I use the script
- Put the above script on form’s onload event
- After the execution of script form looks as below

What are we doing in script
- Get the Activities IFrame id (i.e., areaActivitiesFrame)
- When the IFrame load completes (i.e., readyState == “complete”)
- Get the “Include” dropdown control (i.e., ‘crmGrid_Account_ActivityPointers_ViewControl’)
- Remove the ‘Related “Regarding” Records’ option
Note – The above script is unsupported which is not recommended and works for pre & post UR 12
