Definition

This flag indicates where a message variable comes from (e.g. the request number) when a message is sent to the application log.

This information can, e.g. be used later to replace temporary message variable contents by permanent values.

Example:

Message variable 1 contains the temporary document number $0005 when the message is sent. When this document is saved, the permanent number 12345 is assigned. The value $0005 has little meaning in the log and should therefore be replaced by 12345. This is difficult if the log contains other messages with temporary contents, perhaps even $0005, although this document number is not meant, (e.g. it could be the number of an implicitly created, dependent document).
Specifying the origin of a message variable in this field makes replacement safer, because you know where the contents come from.
