AO Max ID accepts a single stream with a numeric ID field as input. It scans that field to find the maximum ID value and appends the maximum value to all records for use in AO Constant Key and AO Constant Key Advanced.

Note that this macro requires the processing and temporary storage of every record in the stream. If you have records in a database, it is better to query the database for the maximum ID using an SQL statement like SELECT COALESCE(MAX(ID),0).
