Hi,
what is the purpose of the record group?? LOV, list item?
The error message frm-41072 info from Online help:
Cause:  
Caused by one of the following
1. Duplicate column names in SQL statement.
2. Invalid record group name.
3. Query is invalid.
Action:  Check the group name and/or correct the SQL statement.
Try running your query from sql plus and make sure it works.
After, modify your code to verify if the record group has been created already.
This sample is available on forms online help:
/*** Built-in: CREATE_GROUP_FROM_QUERY
** Example: Create a record group from a query, and populate it.
DECLARE
rg_name VARCHAR2(40) := 'Salary_Range';
rg_id RecordGroup;
errcode NUMBER;
BEGIN
** Make sure group doesn't already exist
rg_id := Find_Group( rg_name );
* If it does not exist, create it and add the two
** necessary columns to it.
     IF Id_Null(rg_id) THEN
     rg_id := Create_Group_From_Query( rg_name, 'SELECT SAL-MOD(SAL,1000) BASE_SAL_RANGE,'
     ||'COUNT(EMPNO) EMPS_IN_RANGE '
     ||'FROM EMP '
     ||'GROUP BY SAL-MOD(SAL,1000) '
     ||'ORDER BY 1');
     END IF;
/* ** Populate the record group */
errcode := Populate_Group( rg_id );
END;
