## Post #1 by @thomas.beale

There appears to be a BMM reading error in AD, because the inherited accuracy fields are not computed correctly in concrete descendant types:
![AD-accuracy|690x403](upload://fOyxmha8EK7iUZn04FmjSOlUKz5.png)

The `accuracy: ANY` field should have been replaced by the `accuracy:REAL` field, which is inherited from `DV_AMOUNT`.

This is probably occurring for all redefined fields...
