Cause and prerequisites

1. The algorithm for the selection options is currently as follows:
a. When you start a program, the default values are displayed.
Due to the default value, the OPTION is determined (for example, 'EQ') and the respective internal table is supplied.
b. If no default exists for a SELECT-OPTION, the respective internal table is empty.
c. If in the first instance a selection is entered in a selection criterion that was previously empty (that is, the table was empty), the respective OPTION is determined (for example, 'CP' with selection 'A*') and the internal table is supplied.
d. If an existing selection is changed (for example, by overwriting the value with SPACE or resetting the entry with '!'), the OPTION is then not changed automatically. It is feasible that you may want to limit by EQ SPACE.
Solution

1. To completely cancel the selection, use the pushbutton "Delete selection".
You should also use this button in this problem.
2. From 3.0, the user guide will be changed: (a) - (c) as 1. Instead of (d) new:
d'. When resetting an entry, the entire line of the internal table is deleted.
Selection on initial value only with special function key or pushbutton.
