Hello Karthik,

This can be done via Client script. Based on the condition you have to add or remove the choice values. Please refer.

Hello

i hope this could be helpful :

removeOption

void removeOption(fieldName, choiceValue)

Removes a specific option from a choice list.

Note: (Versions prior to Eureka) When items are removed from a choice list by a Client Script, Google Chrome and Apple Safari will still display those items. When one of these web browsers is used, the "removed" items will be displayed as read only in the choice list and they cannot be chosen.

Parameters:

fieldName - specifies the field.

choiceValue - specifies the value stored in the database as a choice.

Returns:

void

Example: Remove the '1' Option from the Priority Field

g_form.removeOption('priority', '1'); 

Example: Remove the 'Closed' State Option if the User is not an Admin

function onLoad() { var isAdmin = g_user.hasRole('admin'); 
var incidentState = g_form.getValue('incident_state');
 if (!isAdmin && (incidentState != 7)){ g_form.removeOption('incident_state', '7'); } }

Hi Karthik,

You want to set the state field based upon the state field value? that can be done with onChange() client script,

How about this condition If On Hold: Resolved,In progress, cancelled. ??

Something like this should help,

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

return;

}

//Type appropriate comment here, and begin script below

if(g_user.hasRole('admin'))

{

if(g_form.getValue('state') == '2')

{

g_form.clearOptions('state');

g_form.addOption('state', '2');

g_form.addOption('state', '3');

g_form.addOption('state', '8');

}

}

}
