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.

In this situation, there is no error message at the top of the screen 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.

To avoid incompatibilities, follow these guidelines:
  • 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 must have a blank or OMIT usage code in the form.
