Message class: BRAIN_SUP - BRAIN messages (for use by support)
Message number: 016
Message text: Selection variable &1[&2] cannot be replaced from &3[&4]
Variable &V1&[&V2&] is a select option and should be replaced with the
value of variable &V3&[&V4&]. But &V4& is no select option. As this does
not make sense, the system does not support this replacement.
Variable &V2& cannot be used.
Change the variable &V2& (especially the replacement option).
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
