Validating the input screen

Former Member — Fri, 20 Apr 2007 06:55:50 GMT

How to validate the input screen as like the web page screen

Example:

If we are giving the integers in place of characters then it should throw the error like “please use the character fields”. The validation should occur, On spot.

Only after this validation, the cursor should go to the next input field.

Hi,

Declare a Parameter like

parameters: p_str(10).

in the at selection-screen even t write the validation like:

data: p_var(10) value '1234567890'.

if not p_str is initial.

if p_str CS p_var (means if the entered value contains string like numbers)

message e000 with “please use the character fields”.

( instead of CS you can use CA contains any)

endif.

reward points if useful

I dont think, without any event you can check it. At least ENTER is required.

Bcoz cursor movement & even tab key is not recognised as a FCODE.

Hi,

If you are giving integers, then there might be possiblity that it may be a character.

For ex., if you giving 1 in character,eventhough it is integer it can be a character also.So you cannot validate it.

But if you want to restrict numbers,then you can use the following.But it will work only if you press enter or execute button.

parameters : p_c1(4) type c modif id z1,

p_i type i.

at selection-screen on p_c1.

if p_c1 ca '0123456789'.

message i000.

endif.
