When creating an approval request with the standard function “Send Approval Request”, BC checks if an approval user is absent (due to table “User Absences”) at the time when the approval request is created. If so, the approval request is directly delegated to the substitute(s) due to the definition in table “Approval Substitutes”.
Important: as it is possible to define a “Workflow User Group” as substitute for a User (i.e. multiple substitute users), the system must automatically split one existing approval entry into multiple approval entries, one for each substitute user of the Workflow User Group.
