Duplicate Mapping Errors usually occur in the tagging done in the financial statements. For more information on how to resolve them please follow this link - How to Solve Duplicate Mapping Errors.
A text (Textblock or String tag) Duplicate Mapping Error will make itself apparent via red markings in the "Text Tagging" tab. You will also see that both occurrences of the tag have the Type set to "Text Content".
You can resolve this validation error by doing one of the following.
- Delete the tags and reapply them (make sure you create a continuation the second time you apply the same tag).
- Follow the steps to create continuations manually - instructions here.
If this is done correctly, the Text Tagging tab will appear with Text Content and Continuation as shown below.
If you need to check the order of your Continuations, follow the information on the page here - Changing the Order of Elements in a Continuation.
