When I do a syntax check in the a routine within inlude ZXRSAU02 of FM EXIT_SAPLRSAP_002, I get an error. This object has been in production so I must be doing the syntax check incorrectly. The error is 'Field i_t_data is unknown. It is neither in one of the specified tatble nor defined by a 'DATA' statement. This is strange because this field is defined in main body of this user exit. Please advise the correct way to do syntax check.
