Fixing Common Errors

Avoiding Common Errors

The following are common errors that you can easily find and fix while reviewing XBRL and the document:

  • Extra spaces or hard returns after numbers or text in table cells
  • Fact Properties that are incorrect or haven’t been set:
    • Accuracy
    • Units and item types
    • Currency type
  • Roll forward beginning and ending dates that need to be updated
  • Dates that are not set, incorrect, or don’t match the Date Type for the concept (Instant vs. Duration)
  • Dimensions that are numbered or mistyped, such as Director 1, Director 2, and so on

Fixing Common Errors

Here are some common errors that appear after XBRL validation with possible solutions.

Error Message Reason/Additional Information Check the Following
Duplicate facts exist in your document. XBRL facts are duplicates if they have the same tagging information and matching units but have different fact values or accuracy settings.
  • Are Shown In and Accuracy for a number the same? For example, Shown In might be in ones and Accuracy in thousands. While the document presentation can be different, the source should be identical.
  • Make sure the XBRL date is correct. For example, the date might be for a 2016 value, but is tagged as a 2015 value, thus conflicting with another 2015 value.
  • Does one fact need a dimension to clarify the difference between two values?
Fact has an incorrect or missing fact value, date/date range, or unit. Review the information provided with this error message to find out what is wrong. If you are not able to determine the issue, follow the possible solutions for this error.
  • Check the date to make sure it’s the correct date type — is it an instant date that is tagged with a duration date concept or the other way around?
  • Review the XBRL Fact Properties to check for missing fact values, missing units, use of the word “nil” on a 0 source value, and use of a dash or word instead of a real numerical value.
An unexpected error occurred, please contact your Customer Success Manager [ix11.4.1.2:continuationChainNested] This happens when a paragraph has identical text blocks applied to it. Check the paragraph and remove duplicate text blocks.
Fact is using a dimension or member that is not compatible with the line item concept. To correct the issue, choose a dimension and member that is compatible with the taxonomy. Dimensions are applied based on the line item concept chosen. Use the dimensionality tool to change the dimension and member to one that is compatible with the concept.
Fact has a value which is less than zero. This concept should not have a negative value. If the value is displayed as a negative in the document you can use the "Reverse Source Value Sign" option in fact properties. Most XBRL values should be positive. There are a handful of exceptions, including when the dimension allows for a positive and negative value. Review the value and tagging to see if the concept requires a positive value from an XBRL (accounting) standpoint. If so, open the Fact Properties for this value and reverse the fact value sign to show it as negative in the document, but retain its positive value in the XBRL.
The displayed value for this fact is incompatible with iXBRL requirements. You may need to review the format category ("Accounting", "Currency", "Date", etc) for the value of this fact so Wdesk can properly format the data for iXBRL. However, some displayed formats are not supported by iXBRL and you may have to adjust how this fact is rendered into the document.
  • Check the format of the value, including the source. For example, does the concept require a date format but you are using accounting? If so, XBRL reads this as a monetary value, not a date. Click the cell and check the format in the toolbar to see its formatting.
  • Are you using the word "nil" on a 0 source value?
  • Are you using a dash or a word in place of a value?
Wdesk cannot determine the correct data type of this fact. Please review the format category ("Accounting", "Currency", etc) for the value of this fact.
  • Check the format of the value, including the source. For example, does the concept require a date format but you are using accounting? If so, XBRL reads this as a monetary value, not a date. Click the cell and check the format in the toolbar to see its formatting.
  • Are you using the word "nil" on a 0 source value?
  • Are you using a dash or a word in place of a value?
Mandatory facts missing A filing document requires some facts; see the Mandatory Facts article. This message will provide you with the list of mandatory facts that are missing. Make sure you apply the concepts in the list to the appropriate fact.
Fact defined with a missing unit, please review the tagging for this fact. A fact might be fully tagged, but the Fact Properties are not completely set or are set incorrectly. Open the Fact Properties for the value and check the Unit. Does it need to be a number, share or monetary value per share (based on concept requirements)?
