Hi Pranu,

You can proceed in the following way:

1. Declare are constant variable with those 3 special character.

DATA: LC_VAR TYPE STING VALUE '~!@#$%^&*()-+={}[]\|'.

2. From the Screen/UI in the PAI event, you have to write a module to check the syntax.

This is the code snippet:

if lv_value CA lc_var.

message s(messgae_no) Display like 'E'.

< Further Logic for error handling >

Endif.

You can put here any branching instruction by either call screen transaction or anything else.

Have a look at this Demo Code: DEMO_DYNPRO_FIELD_CHAIN

Hope this will help.

Samantak.

Hi ,

DATA: LC_VAR1 TYPE STRING VALUE ' -*/'.

if ZTAB2-REGNO NA lc_var1.

message E010(ZMSG) with 'Enter Valid Registration Number'.

Endif.

as pre the code u have given me it is accepting only if i enter any one of the special character i specified in the local variable.

but my requirement is it should not accept if i give any other special character apart from the characters i specified in the local variable.

it should accept me if i don't enter any special character also
