Primarily used to convert unstacked datasets, like the Final Parameters Pivoted worksheet output from a PK or NCA model. The Stacker object moves values stored in column headings into rows. When data is stacked by parameter, the separate parameter columns are “stacked” in one column and the parameter values are arranged beside each parameter in the stacked column.
Use one of the following to add the object to a Workflow:
Right-click menu for a Workflow object: New > Data Management > Stacker.
Main menu: Insert > Data Management > Stacker.
Right-click menu for a worksheet: Send To > Data Management > Stacker.
Note:To view the object in its own window, select it in the Object Browser and double-click it or press ENTER. All instructions for setting up and execution are the same whether the object is viewed in its own window or in Phoenix view.
The Mappings panel allows users to specify which columns in a worksheet are involved in the worksheet transformation. Required input is highlighted orange in the interface.
Carry: Data types mapped to carry over into the stacked output worksheet. Note that the order in which the Carry columns are selected is the order they will appear in the output worksheet.
Stack: Data types to stack in a single column. The values in each stacked column are then placed beside each column header in a separate column.
-
In the Stacked Column Name field, type a name for the output column that contains the stacked data.
-
In the Estimate Column Name field, type a name for the output column that contains the values that are matched with the stacked data.
-
Check the Include Missing Values box to carry empty rows through to the results worksheet. This allows the user to keep track of records for which a parameter (e.g., a PK parameter) could not be calculated for some reason.
-
In the Unit Column Name field, type a name for the output column that contains the units that are matched with the stacked data.
-
Clear the Use Units checkbox if the input worksheet does not use units or units are not needed in the output.
The Stacker object generates one worksheet and one text file.
Stacked: The stacked data types and their associated values and units, if any.
Settings: Text file containing input worksheet used and the options selected.
