So your onChange script would look more like this now to only run for one specific Catalog Item:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var catitem = '';
if (this) { //Service Portal method
catitem = this.cat_g_form.getUniqueValue();
} else { //native UI method
catitem = parent.g_form.getUniqueValue();
}
if (catitem == '964185f78726a9100b25986d3fbb35c1') { //replace with the sysid of your Catalog Item
var ProjectStartDate = g_service_catalog.parent.getValue('value of project start date of catalog item');
var ProjectEndDate = g_service_catalog.parent.getValue(‘value of project end date of catalog item');
var WorkPackageStartDate = g_form.getValue(‘MRVS wrkpckgestart date’);
if (ProjectStartDate != '' && ProjectEndDate != '') {
if(!((WorkPackageStartDate >= ProjectStartDate) && (WorkPackageStartDate <= ProjectEndDate))) {
g_form.addErrorMessage("Please enter the dates in between Your Project Start Date and Project End Date i.e " +ProjectStartDate+" and "+ProjectEndDate);
g_form.clearValue((‘MRVS wrkpckgestart date’);
}
} else {
g_form.addErrorMessage('Please Enter Project Start Date and Project End Date');
g_form.clearValue((‘MRVS wrkpckgestart date’);
}
}
}
then create an onLoad Catalog Client Script that applies to the Catalog Item:
function onLoad() {
if (this) { // only needed for Service Portal
// make the g_form object for the parent item available from the MRVS window
this.cat_g_form = g_form;
}
}
