​SubsetElementGetIndex retrieves an element’s index in a subset. If the element doesn’t exist in the subset, then the function returns 0. If the index is not between 1 and the size of the subset then the function return error and process will be aborted.

SubsetElementGetIndex(DimName, SubsetName, ElementName, StartIndex).;

​DimName = Name of the Dimension where subset exists.​
SubsetName = Name of the subset from where we want to retrieve element index. ​
ElementName = Name of the element which we want to retrieve index from the subset. ​
StartIndex = Index number to start searching from. This value must be between 1 and the size of the subset. 

Use SubsetElementGetIndex to retrieve an element’s (Sales Amount) index, demonstrating the result with different StartIndexes.
