Is there a limit for number terms that can be associated to a document

Question

I have a document library with documents. I need to associate the documents to terms in a terms store. I have added a managed meta data column.

Is there a limit to the number of terms that can be assoociated to one document?

Answer 1

The first Managed Metadata field added to a list is allocated four columns:

• A lookup field for the actual tag

• A hidden text field for the string value

• A lookup field for the catch all

• A lookup field for spillover of the catch all

Each subsequent Managed Metadata field added to a list adds two more columns:

• A lookup field for the actual tag

• A hidden text field for the string value

The maximum number of columns of Managed Metadata is calculated as (14 + (16 * (n-1))) where n is the row mapping value (default of 6).
