Data in Microsoft Office Excel tables of data caches often has no unique identifiers. To transform data into context-related data with a unique ID, you define ER named ranges and assign a name starting with "ER_"
You can tag and save each value of a range. With the Tag Monitor, you can track the changes of specific report values and provide a concise overview of changes applied to those values. For example you can see how the total amount of liabilities has been modified over the time the annual report has been elaborated.
Procedure to create ER range

In the Data Link the named range will now appear with its <tag> name. In this example, Q4TABLE
Note also that the ER_KEYS values are not displayed, only the labels and values
