Troubleshooting: Computed fields validation

Computed fields validation is complex since they are only valid in relation to the IBM OpenPages® with Watson™ reporting framework, which may change in response to a change in the OpenPages with Watson object model.

Therefore, we provide several forms of validation.

When you create or edit a computed field, the field is validated against the primary namespace as well as all alternate namespaces. If any of the validation checks fail, then the UI will not allow you to save the computed field until the problem is corrected. OpenPages with Watson maintains strict validation checks in this area because a slight error here can have an extensive ripple effect that is hard to identify and correct.

Also, due to the complexity of the computation engine there are certain cases where two computed fields will be valid by themselves but invalid together. A common example is where two computed fields reference different Object ID columns. In order for the computations to be grouped correctly they must all have the same Object ID column value. Therefore, we provide validation functionality across both an entire Field Group definition as well as an Object Type definition.
