To create a function manually:
Example 22-1 Syntax Guidelines
See Function Descriptions for the syntax of individual functions.
To work with a shared connection, you must add to the function the WSFN identifier, which specifies a workspace function, along with a connection string. The format is:
WSFN|ProviderType|Server|Application|Database
For example, in the HsGetValue function for a shared connection to an Oracle Essbase data source, the WSFN identifier and connection string is added to the function as follows:
=HsGetValue("WSFN|Essbase|myserver|Sample|Basic","Market#South")
For ProviderType
, use one of the following case-sensitive strings:
Essbase
HFM
(for Oracle Hyperion Financial Management)
HP
(for Oracle Hyperion Planning)
For Financial Management, the Database
parameter can be omitted, or it can be the same as the Application
parameter. For consistency, Oracle recommends entering the application name for the Database
parameter.
Private connection parameters can have these values:
Empty: the default connection
HsActive: the active associated connection
The user-defined name for a private connection
If you specify a private connection, it must precede the POV.
The POV is composed of dimension#member pairs, for example, Entity#Connecticut.
Parent-child relationships are designated by a period, for example, Entity#UnitedStates.Maine.
The connection and POV can be grouped as one parameter, for example “My_connection;Entity#UnitedStates”.
Alternatively, they can be split up into multiple function parameters, for example, “My_connection”, “Entity#UnitedStates”, “Account#Sales”.
If the connection and POV are in the same parameter, the connection and each dimension#member pair are separated by a semicolon (;), for example, “My_connection;Entity#UnitedStates;Account#Sales”.
