If a window displays a file with links, WinDev will run a
« Read by key » for each linked field in each record in the table.
This will result in a large number of access to the AS/400, and the cache will
not be used, because WinDev reads one record at a time.
To optimise this feature, we suggest two ways:
• Use SELECT statement with INNER JOIN clause.
• Create a logical join file on AS/400, import it in the analysis, and use it to fill up the table
