Form and data incompatibility

There might be times when you modify a form in such a way that the form is inconsistent with the data. This situation is treated differently from error and warning conditions. There is no error message at the top of the screen when the cursor is positioned, and the CHECK command does not identify the problem. Instead, when you try to display the report, a message is displayed and the form panel containing the incompatibility is displayed.

Examples of possible incompatibilities:

• The number of columns in the form (excluding defined columns) and in the data must be equal.
• Edit codes in the form must match the data type for each column in the data.
• Every LONG VARCHAR and LONG VARGRAPHIC column in the data must have a blank or an OMIT usage code in the form.
