Creating Working Extracts
Working extracts can only be created at the location where the parent extract is primary.
Working extracts do not need to be added to MDBs. When selecting an MDB that includes databases for which you have working extracts, it will actually write your data to the working extract.
When issuing data from a working extract, it will be issued to the database from which the working extract has been created.
In order to issue data from an extract which has working extracts to an extract further up the extract tree, there must be a user who does not have a working extract: see the following diagram.
A working extract inherits the write access of the parent access. That is if the parent is primary at the location of the working extract than it can be written to, otherwise the user will only have read access.
