GST State capture option is required to track inter-state sale. Therefore same cannot be restricted.
GST State should applicable only in case of GST No is there
Problem statement is :
POS user creates Customer master at store level and store user change very frequently. therefore it is not fusible to trained them always.
normally user see State and he select state over there he doesn't bother about this selection (impact of that), it always affect only at the time of filling return.
to avoid such situation suggestion is GST State should be applicable only in case of If User provides GST No.., it should pass exception message.
You won't be notified about changes to this idea.
