Selection program & was changed manually

What causes this issue?

The selection program generated for a help view was changed manually.
The program was therefore not generated again during activation.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check whether the program still corresponds to the current view
definition.
If the manual change is no longer necessary, the comment line at the
start of the program must be removed.
The program is then generated again when the help view is activated.
