since you already have them in the dataenvironment of the report form, you need to create another part of the child tables tag. Example: if tag is comprised of only one field on your child table you need to add another field that you want the child table to be order by.
Thus, INDEX ON ID TAG TAG1 change to INDEX ON ID + MyFieldToOrderChild TAG TAG2. in this case, with TAG2, the child table will be order by id followed by MyFieldToOrderChild.
Or you can take the tables out of the dataenv. and use sql select statment.
Work as if you don't need money
Love as if you've never been hurt before
Live as if this is your last day to live
Dance as if no one's watching
