Actual condition is it shouldn't accept numbers less than six digits.

Hi Narashima,

Get the string length if it is less than 6 ,

give an error message.

as below,

DATA : p_empno TYPE char10.
DATA : lv_len TYPE i.
p_empno = '1234'.
lv_len = strlen( p_empno ).

IF lv_len < 6.
MESSAGE 'Incorrect lenght' TYPE 'E'.
ENDIF.

Thanks,

Hi,

Use the Function STRLEN to get field length.

Eg:

data : lv_val type c length 5 default 'ABCDE',

lv_length type i.

lv_length = strlen ( lv_val ).

Write 😕 lv_length.

Ouput would be 5. lv_length has value 5.

Hi Narasimha,

One way to achieve this is through string manipulation.

1. We shall pass the entered employee number on screen to a string variable.

2. Get the length of that string variable.

3. Validate whether the length is greater than 6. If it is less than 6, then raise an error message.

For syntax to get length of string variable, use F1 help.

Hi Narasimha,

For the above mentioned validation you can put condition in PAI like

if (emp_no > 99999).

{

only then accept emp_no

}

else.

{

give error message.

skip/exit.

}

condition can be modified like if(emp_no >= 100000).

then accept the employee nos.

Hope it helps!!!!

Why don't you check the employee number with a HR infotype ?

In PAI, validate the screen field value.

PROCESS AFTER INPUT.

CHAIN.

if STRLEN ( Screen-Field) LT 6.

Message: 'Less than 6 character not allowed !'.

endif.

ENDCHAIN.

Hi Narasimha Swamy

Place the codes in PAI

if screen field  LT 6   " means
Error Message
Else.
" Proceed further
Endif.

you can place the code inside of chain endchain statement also

Go to Screen Section - PAI (Process After Input)

FIELD <Your field name> MODULE <your module name>.

In Program section,

MODULE <your module name> INPUT.

Your logic goes here..

If Employee number is < 100000 ( ie lesser than 6 digits)

MESSAGE 'Minimum length of employee number is 6 digits...' TYPE 'S' DISPLAY LIKE 'E'.

endif.

ENDMOUDLE.
