In the exit IWO10020 suggested by Rajkumar , use the following code in the include ZXWO1U06 to have your check and see it working.
DATA: v_eqtyp TYPE eqtyp.
SELECT SINGLE eqtyp FROM equi INTO v_eqtyp WHERE equnr = caufvd_imp-equnr.
IF v_eqtyp <> 'U'.
MESSAGE: 'You can not create Orders on Equipment types other than ''U''' TYPE 'E' DISPLAY LIKE 'I'.
ENDIF.
This throws the following error when the equipment is not of type 'U'.
Good luck
