System Last ID
The System Last ID screen stores the values of the most recently used (and presumably the highest) ID number for several different record types in the system.
The system automatically updates each of the values every time a new record is added to the appropriate table. It is rare that you would ever need to change this information manually, and you should do so only with extreme caution.
To access the System Last ID page:
In Administration, select System Setup > System Last ID.
Finding the Highest ID
To find the highest ID number currently in use for each of the listed tables, click the Find Max ID button on the banner. This button populates the MAX ID column on the page. This tells you the highest ID number that is in use in each of the tables.
Under normal circumstances, the MAX ID should be equal to the value in the Last ID column.
If the MAX ID is higher than the Last ID, the value will appear in red to alert you to a potential problem. You should correct it by setting the Last ID to match the MAX ID. If the system attempts to write a record with an ID that already exists, an error will occur.
If the MAX ID is lower than the Last ID, it does not necessarily indicate a problem. It could be lower because of deleted records, or records that were started but never saved. In any case, you can either choose to leave it alone, or you can safely reset the Last ID to match the MAX ID.
Remember to save any changes that you make after you are finished.
