This error supports automatic activation. To activate the sample population editor to fill out the population:
From the Error List, double click the error to select the FactType, open the Sample Population Editor, and provide an instance for the blank cell(s).
In the verbalization browser, the error in question will display with the FactType verbalization and is hyperlinked to activate the error.
From the FactType shape on diagram, double-click the edge of the FactType to activate the next error.
If you don't want to see population errors, then
Click on the backgroun of an ORM diagram
Open the Properties Window and activate the 'Error Display' dialog
Uncheck the 'Sample Population Errors' category of errors, or expand and turn off the specific 'Incomplete FactType Sample Population' error
These errors have no affect on SQL generation. In fact, SQL generation is done for any FactType and ObjectType that is sufficiently error free. For example, a FactType with no internal uniqueness or a ValueType with no DataType does not map, but these elements are mapped as soon as the error states are cleared. Sample population errors are not critical for SQL generation.
Warning vs Error is a matter of perspective. If your goal is to provide a fully validated model with no population errors, then this is definitely an error. If you want SQL structure, then it is probably a warning. If you want to prepopulate the SQL model [we don't do this yet], then it is an error again. Short of controlling error display, NORMA doesn't currently have a mechanism for error level. This could possibly be added in the future, along with finer-grained control over error display (display graphically, on model browser, in verbalization browser and reports, and in the error list). However, these additional facilities are not high on our priority list.
