This function returns the alias from the specified
alias group at index. The OLAPAlias function is designed specifically
to allow you to view the alias names that are associated with a member
in a specified dimension within a specified database. The function
returns the alias name which is specified by the PowerOLAP user within
the Modeler when creating an Alias Group. The function also takes
as a parameter the name of the alias group as created and the index
of the alias in that group.
The function has the following syntax:-
Syntax: OLAPAlias
(database, dimension, group, index)
Explained below are the 4 parameters that have to
be entered when building this function.
- Database : Enter the name of the database which
has the dimension and alias group that you want to access / enter
the cell reference which has the name of this Database.
- Dimension : Enter the name of the dimension
in the above mentioned database which has the Alias Group you
want to access / enter the cell reference which has the name of
such a dimension.
- Group : Enter the name of the Alias Group you
want to access that exists in the dimension and database mentioned
above / enter the cell reference which has the name of such an
alias group.
- Index : Enter the index number for the alias
in the above mentioned Alias Group within the specified dimension
of the specified database / enter the cell reference which has
the index as a value.
Remarks
- If a connection is not established with a database
the result will be a #value.
- The parameter for Index must be a positive
real integer and should correspond to the value that the function
has to return.
- There must be the same alias group existing
in the database as entered for the Group parameter above.
- All arguments are compulsory and neither argument
is optional.
Example
This function may be easier to understand with an
example.
- In order to build this function with more ease,
open the specific database and bring a slice from that database
into excel. In this way you will have connected to PowerOLAP because
you now have the OLAPOpen formula automatically on your sheet
when you bring a slice of the cube into Excel.
- In Excel, use the menu: Insert -> Function
and select PowerOLAP from the drop down list.
- Choose the OLAPAlias function from the list
of functions provided and click "Ok".
- When building the formula enter the cell range
for the database name, the dimension name and type in the name
for the alias group in that database as well as the index for
the alias. If you don't want to manually enter the alias group
name you can use another function called OLAPAliasGroup in a cell
to get the alias group name/names and then use that cell as a
reference for a formula.
- In the following example B2 is the cell that
holds the database name, B6 is the cell that holds the dimension
name, "DataLoadCodes" is the name of the
Alias Group and the number 3 is the index of the alias in the
group whose value the formula returns.
=OLAPAlias($B$1,$B$6,"DataLoadCodes",3) |
The above formula returns a value = 11 which
is the value for the alias in the database "Acuity"(B1)
in the dimension "AP_Vendor"(B6) in the Alias Group called
"DataLoadCodes".
