OB28 user exit validation

Hi all,

I have been trying to figure out this for a couple of days now. In ZRGGBR000 where you put the user exits, I'm trying to figure out how to pass BOOL_DATA to my user exit.

heres my code:

FORM GET_EXIT_TITLES

exits-name = 'UZ900'.

exits-param = c_exit_param_class. "complete data

exits-title = text-105.

APPEND exits.

ENDFORM.

FORM uZ900 USING bool_data

CHANGING b_result.

ENDFORM.

now when the generated program calls form uz900, I'm getting a short dump saying the program call pass 1 parameter while uz900 is expecting 2. Does anyone know how to solve this?
