Definicja inflation index version

A system object that allows you to define more than one set of values for an inflation index, if necessary.

In most cases, one version should suffice, but you may need to create a new version if, for example, you have run one of the inflation adjustment reports and the values that you used are incorrect. Since you cannot change values that you have already used, you would create a new version (by copying all the entries across from the old one) and use that instead.
