How To Fix BRAIN255 - Variable &2 is ignored if no entries are made at runtime

BRAIN255 - Overview

• Message type: E = Error

• Message class: BRAIN -

• Message number: 255

• Message text: Variable &2 is ignored if no entries are made at runtime

What causes this issue?

If no value is specified for an optional variable, the system assumes
there are no restrictions and displays all data.
However, variable &V2& for characteristic &V1& is used with additional
including conditions in the fixed filter. Therefore, no input for &V2&
is interpreted as though the condition does not exist.
If all including conditions for &V1& are optional variables, and no
entry is made for these variables, all data is displayed.
