Using TCM Expert to Generate an Apportionment Weights Table for CSV
Files
To use TCM Expert to generate an Apportionment Weights Table for CSV files:
1. Select TCM Expert from the “TCM Initial Menu” (page 66).
The Specify Custom Directory dialog box appears.
2. Select a custom folder and click OK.
3. Select TCM Expert > Generate Expert Apportionment Weights.
If you are at the capacity planner authorization level, TCM displays the TCM password dialog
box. Log on as an administrator or superuser. Enter the TCM administrator or superuser
password. (The defaults are “admin” and “super” respectively.) Click OK.
The Generate Expert Apportionment Weights dialog box appears.
From this dialog box, you can:
a. Select or enter the name of the capacity history that is updated automatically after the
weights are generated. The capacity history is created if it does not already exist.
b. Select a name for the source of the transaction counts by selecting an apportionment
table file. If you have transaction count files, TCM Expert automatically identifies them.
If transaction count files are present, they override a Transaction Count table if both are
present. If you do not have either a Transaction Count table or transaction count files,
you must create a default table. For more information, see “Creating a Default Transaction
Count Table and Workload Apportionment Weights Table” (page 181).
TCM Expert uses the name entered in the Apportionment Table file as the output for
placing its resulting apportioned weights. In the preceding example dialog box, DEMO
is both the name of the Transaction Count Table and the Apportionment Weights Table
(.AWA file).
If you are a TCM super user, the field Percent of Selected CSVs used to generate appears.
If you are not a TCM super user, this field is hidden. The default is 67 percent. This
percentage is the percent of CSV files randomly selected by TCM Expert to generate the
apportionment weights.
