iXBRL Diagnostic error - Does not specify a valid entity

When generating an iXBRL report, you may encounter the following error, reading Context "problem context" does not specify a valid entity.

This typically comes up where new contexts have been improperly created through the method described here, but also can be triggered if the Registered Number is not populated in the wizard.

To correct, the option in the bottom left to correct the error will jump you to the context setting menu for the problem context. 

Here, you would want to ensure the following fields are populated correctly.

Further Information

These fields ensure the report will meet the requirement for the tag to identify the entity to which it applies.  The scheme represents the URL of the identification scheme, and the identifier represents the code for the relevant entity within that scheme.

This information is calculated by the software from wizard options, and then pulled in by automatic references.  All contexts within the report should have the same calculation in these fields, so please consult a standard context to gain the correct entry.  They do vary between templates, but typically it should be of the form or similar to cvData("XBRLSCHEME")  and cvData("XBRLID") in the respective fields.  If you are using the IFRS Financials template (a distinct template to AccountsAdvanced IFRS), then you should refer to a previously used context.
