Deleting the Assignment of Additional Structures

If you want to delete an additional structure, you must first call the additional information screen for the corresponding database table. In this context, deleting an additional structure means removing the assignment to a data source table. To do this, place the cursor on the structure and choose Delete .

You can only delete if the fields of the structure are not used in a Query. That is always the case where fields of the structure have not yet been included in any field groups of the InfoSet.

However, the system rejects any attempt to delete a structure that has already been used in Queries, as long as those Queries still exist.

You can determine whether and in which queries a table field is used. To do this, place the cursor on a structure field and choose  Environment Directories Queries for field or choose Queries for field in the lower right-hand box. Change the Queries so that the additional structure fields are no longer used.
