MULTIPLICATION (*)
Basic Overview
Description  Multiplies nodes by performing a a join along the shared levels of the nodes (dimension union). The result has all the finest levels that are present in either of the nodes. 
Signature  Node1 * Node2 
Parameters 

Examples
Example with all Shared Dimensions
Node1 =
Year  Measure 

2018  2 
2019  4 
Node2 =
Year  Measure 

2018  3 
2019  1 
Node1 * Node2 =
Year  Measure 

2018  2 * 3 = 6 
2019  4 * 1 = 4 
Example with some Shared Dimensions
Node1 =
Year  Measure 

2018  2 
2019  4 
Node2 =
Year  Product  Measure 

2018  A  2 
2018  B  0 
2019  A  1 
2019  B  4 
Node1 * Node2 =
Year  Product  Measure 

2018  A  2 * 2 = 4 
2018  B  2 * 0 = 0 
2019  A  4 * 1 = 4 
2019  B  4 * 4 = 16 
Example without Shared Dimensions
Node1 =
Year  Measure 

2018  2 
2019  4 
Node2 =
Measure 

2 
Node1 * Node2 =
Year  Measure 

2018  2 * 2 = 4 
2019  4 * 2 = 8
