Tandem Capacity Model (TCM) Manual

To override TCM Expert’s calculations for any category marked with a Y:

values you believe are correct under the transaction columns. To finish entering your data,
you must press Return before selecting Calculate Now or pressing a function key.
c. Select Options > Protect Admin Fields.

TCM automatically updates capacity history using the automatically generated
Apportionment Weights table.
Updating Capacity History With Selected CSV Files
The Update Capacity History with Selected CSV Files option is available so that you can update
capacity history using any Apportionment Weights table (whether TCM Expert generated it
automatically or you manually generated it). If you use TCM Expert to generate the Apportionment
Weights table, TCM Expert already has automatically updated capacity history, and you need not
use this option.
To update capacity history with selected CSV files:
1. Select TCM Expert from the “TCM Initial Menu” (page 66).
The Specify Custom Directory dialog box appears.
2. Specify a custom folder and click OK.
3. Select Expert > TCM Expert Parameters. Enter in Check History Over Last enough months to
cover all of the dates when the samples were taken.
4. Select Expert > Update History with Selected CSVs. The Update History with Selected CSV
Files dialog box appears. By default, CSV files that have not yet been used to update capacity
history appear in the Selected CSV Files list.
5. Select a History database from the History Database list. You can select from the list of History
files, keep the default History name, or enter a new name.
6. Select an apportionment table from the Apportionment Table pull-down list. You can select
from the list of apportionment tables or keep the apportionment table name.
