problem in dialog programming

27 Views

hello experts,

i have a requirement that in modulepool program,

i have a field (say serialno) which is automatically generated one based on previous no,

now my problem is if user enters the no randomly and if he pressed save that no is storing in the itab.

here my req is i have to restrict the functionality to only automatic generation and if user enters any random value

my field has to reject that value and has to show the message(say "the entered value is not matching with the series, do u want to continue?).

how can i resolve this issue.

can anybody please suggest me with some sample code.

regards

maheshlap.
