Is this a CHARacter or QUANtity field (which one)?

lw_bfquant is a quantity field referring to data element ERFMG.

User enters a value on screen and now I want to check that it is a numeric field and doesn't have any characters or alphanumerics in that.

if lw_bfquant ca '0123456789'.

success.

else.

error message.

endif.

Try this:

REPORT ztest LINE-SIZE 80 MESSAGE-ID 00.

PARAMETERS bfquant TYPE erfmg.

DATA: rem(5) TYPE p DECIMALS 3.

* No need to check for negative - not allowed in ERFMG

IF NOT bfquant > 0.
  MESSAGE e001 WITH 'Quantity must be greater than 0'.
ENDIF.

rem = bfquant MOD '1'.
IF rem <> 0.
  MESSAGE e001 WITH 'No decimals allowed'.
ENDIF.

I think all the other solutions only work for character fields. You can only enter numerics into quantity fields, so you don't have to check that..

I see you have marked this question as "solved" but have not assigned any points or even a "Thanks". Did you solve it on your own? Did none of the suggestions help?
