Role base filtration for Contacts lookup not working in Portal Edit page

Hi

I have applied filtration logic for one Contact lookup field in a section edit page based on User Role and role-based contacts alone getting listed in that field. But when I put the same filter in portal edit page of the section for the same lookup field, it is not showing the contacts. 

Please find below the used code.

Case: Users having Role Id : 'KYC', has to be listed in the lookup field.

Filter code:  Inside Attributes,

"GlbKYC": { 

// Attribute data type.

"dataValueType": Terrasoft.DataValueType.LOOKUP,

// The configuration object of the LOOKUP type.

"lookupListConfig": {

"filters": [

function() {

var filterGroup = Ext.create("Terrasoft.FilterGroup");

filterGroup.add("IsKYC",

Terrasoft.createColumnFilterWithParameter(Terrasoft.ComparisonType.EQUAL, "[SysAdminUnit:Contact].[SysAdminUnitInRole:SysAdminUnit].SysAdminUnitRoleId", "C14E5787-4BF5-4FA8-A407-96FB942A02E2"));

return filterGroup;

}]}},

Kindly help to resolve this.

Regards
