Unable to get previous value using BR

[Karishma Dubey]

Hello,

I am trying to perform some actions based on new value and previous value of BU code field present on user table.

I created after(update on some field value change) BR on user table and writing below code. However I am getting blank value in logs. Please suggest.

if (current.u_sf_business_unit_code.changes()) {
var prevBU = previous.u_sf_business_unit_code;
var newBU = current.u_sf_business_unit_code;
gs.log('previous BU', prevBU);
gs.log('newBU ', newBU);
try {
gs.log('BU changes ');
sn_fd.FlowAPI.getRunner().subflow('global.sml_internal_mover__business_unit').inBackground().withInputs(inputs).run();

} catch (ex) {
var message1 = ex.getMessage();
gs.error(message);
}

}

Hi @Karishma Dubey ,

Generally,  "After" business rule with "Insert / Update" method to get new and old value of CI

What do your logs return when you make it a before BR?

Hi,

Previous object (As the database updation is already done) will not be available for After update BR. Please try doing validations with Before Update BR.
