The issue has been identified as a DPM misalignment and will be addressed in a future reporting framework release. Pending this correction, reporting entities may use the value '(CU:x46) Other Currency (open axis tables)' in template Z 13.00 when reporting aggregated amounts that include exposures in different currencies.
The reference to 'XXX' in the instructions should be understood as an illustrative placeholder representing a currency code format rather than a specific reportable currency value. Therefore, no additional 'XXX' value is currently required in the DPM. The forthcoming DPM review will ensure alignment between the reporting instructions and the available reporting values.
