ENTRY IF clause

[Ghadge,Sameer]

FIELD TRANS-NAME OF FS-DATA ID SAME NOCHANGE                      
                        ENTRY IF VOUCHER-TYPE = "P" SIZE 9 REQUIRED'
>From above code, it seems that TRANS-NAME can only be entered if
VOUCHER-TYPE = 'P' . 
else  user won't be able to enter anything in TRANS-NAME field,
is this understanding correct ?


Thx
Sameer
