The reason why the mapping doesn’t always use the same phrasing as the posts in your financial statement is because the mapping has to be done according to the related taxonomy.
While it is customary to use different abbreviations when creating financial reports, the mapping needs to match the taxonomy element 100%.
For example, you may have a post titled “Personnel cost” in your annual report. That is not the name used in the taxonomy, however, here it is instead called “Employee benefits expense”, and so the mapping needs to reflect that.
In most cases you won’t need to do anything differently as our system of simplified tagging will make these corrections for you.
