in EPM CLOUD business rule how to traverse the dimension in the order of a DATA COlumn

hi All

in the business rule in EPM CLoud - Planning - BSO Cube, we want to traverse all legal entities, based on a data column (PRIORITY),

so primarily we need to perform some business logic on a LEGAL Entity called LE10, which has DATA cell, PRIORITY =1 , followed by LE 5, which PRIORIRTY = 2 and so on,

in the business rule, we can write FIX(@RELATIVE("Legal entity",0)) which will traverse based on the dimension sequencing.

any suggestions? Thanks!
