Therefore relevance identifiers cannot be defined.
A split is defined if either <ZK>Split Max. </>or <ZK>Split Flexible</>
is set and a <ZK>Split Rule</> is defined.
If a split is defined on structure (STR) level, then <ZK>Condition Rules
</> must be defined for each relevance identifier on or relevance
identifier level.
A split can also be defined on relevance identifier level. This depends
on the following requirements:
No split is defined on structure level.
<ZK>Sender Parameter</> is unassigned on structure level.
For each relevance identifier entry on relevance identifier level a
sender parameter is assigned.
All sender parameters are different on relevance identifier level.
If <ZK>Split Flexible</> is defined on relevance identifier level a
split rule is required. A mixture of split rules and condition rules is
<ZH>not </>allowed on relevance identifier level.
