SYMPTOM:
When updating the table structure of a table in Warehouse Catalog, sometimes the modification timestamp is not updated in the interface in Strategy Desktop 9.0.x
ACTION:
The feature is working as designed.
The modification timestamp of the table will only be updated if a major change, such as adding or removing columns, takes place. Minor changes like changing column datatypes will reflect on the column object modification time and not the table modification time.
Contact Strategy Technical Support if further information on modification times is required.
