RWA
Gets attributes from an attribute table. You cannot write back changes to the values of intrinsic attributes but you can write back changes to other attributes.
Note: ROA is the non-writable version of RWA. To disable write back in
a cell values formula, change RWA to ROA or clear the
option in the
Edit OLAP Formula dialog.
See ROA.
Syntax
=RWA( "database alias", "cube", "hierarchy name", "attribute
name", "element name")
Example
=RWA("Best Practices OLAP","Sales","[Product]","Att2_German","[Product].[All Tires].[Car Tires All Season]")
