Syntax meaning in business rule

[Souvick6917]

Hi Team, 

I have a small query on one of the syntax used in Business rule

For reference: if(!current.reason_state){

gs.addErrorMessage(gs.getMessage('Enter a refusal reason,please complete the field "reason for refusal"'));

        current.setAbortAction(true);

}

Please explain the meaning of if(!current.reason_state)

The business rule is running on a customised table with a field reason_state.

Thanks in Advance

It is checking if it is empty or no value.
! is checking for the opposite

so if current record reason state is empty or false write the error message

Hi @Souvick6917 

My understanding say it is for Boolean value, yes / NO to find out.

The ! is the not operator, so it means if “not false” which means true or if “not true” which means false.

Mean current record reason_state field has any value or not , like we have on Inc , is RFC is filed or not.
