Hi all,

iam stuck with the below requirement can anyone please help me out.

There is a custom table named "u_cost_manage" in that table there are three custom fields.

Supplier (reference) field, branch string field, and partner choice box (True/false)

Below is the requirement in a catalog item,

We have a list collector variable named "Branch" list collector, if the branch records are selected then if one of the records has partner as true, then we need to mark the Trusted partner variable select box (True/false) as true else it should be false.

Below is the client script i have tried.

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

if (isLoading || !newValue){

return ;

}

var ga = new GlideAjax('CheckTrustedpartner');

ga.addParam('sysparam_name','check');

ga.addParam('sysparam_ids',newValue);

ga.getXML(function(response){

var answer = response.responseXML.documentElement.getAttribute("answer");

g_form.setValue('trusted_partner',answer == 'true');

});

}

Please help me on this, how to get the trusted partner variable marked as true when one of the list collector record contains the partner field value marked as true.

Thank you,

Balaram.
