The Save Toolbar Button
The system will check the details that you have typed into the lookup table entry. If the entry is valid, the system will save you changes. If the entry is invalid, the system will tell you what you need to change.
The system will also try to save any changes you have made to a lookup table entry if you move to a different entry. If the entry is invalid, the system will tell you what you need to change and return you to the correct entry.
When the system saves changes to a lookup table item, it will re-sort the table into the correct order.
