You can do one thing. Take the user input value into a string variable.

By using the length function of string, do the validation.

Looks like you have some leading zeroes in your variable but which are not shown on your screen. Try to get rid of them and then get the length of the string.

Hi...

put the field on a data of type string, and with STRLEN( WORD1 )

you have the len of the string.


DATA: In TYPE I,
          WORD(15).

word = gi_pmpb_bchid-batchid.
In = STRLEN( WORD)

IF ln 6.
MESSAGE e013(zc8isms).
ELSE.
....
endif.

regard

DESCRIBE returns the attributes of a data object. Length operators, like STRLEN, on the other hand, return a length of the data content.

if strlen( <mytable-fieldname> ) gt 6.

etc...

or lv_len = strlen( <mytable-fieldname> ).

if lv_len (of type i) gt 6.

etc...

put this in code, press F1 on STRLEN for informative help on finding lengths, whether field or table.

Its the length of the column, not the data present in the cell.

Use the internal table value.

try this,

if strlen( wa-val ) le 6.

error.

endif.

Hi,

Give one space between the variable and open bracket and close bracket of the function STRLEN.

eg. STRLEN(< 1 space> <your variable> <1 space >).

Hope this may help you.
