Cannot Use Constants in the HIDE Area

In ABAP Objects and, as of release 7.0, ouside of classes, you can only write variables to the HIDEarea.

In ABAP Objects, the following statements acause an error message:

CONSTANTS f.

HIDE: '...', f.

Correct syntax:

DATA: f1, f2.

HIDE: f1, f2.

Cause:

Interactive list events cause the fields hidden by the HIDE command to be overwritten with values in the HIDE area, which means that they must be changeable.n.
