Using Relations in Dimension Patterns
You can use relations to drive pattern increments. At the time you select a dimension to drive the pattern in a specific direction and specify the dimension increment, you can add a relation for that increment. This allows the incremental value to vary for each instance of the pattern.
You can use the following pattern parameters inside a pattern relation:
LEAD_V—Parameter symbol for the leader value (the dimension you just selected to determine the direction)
MEMB_V—Parameter symbol to locate the instances with respect to the reference entity of the pattern leader
MEMB_I—Parameter symbol to locate an instance with respect to the previous instance
IDX1 and IDX2 —Pattern instance index values, which are incremented for each calculated pattern instance.
* MEMB_V and MEMB_I are mutually exclusive—they cannot appear in the same pattern relation together.
