Predefined templates contain commonly used data fields. However, you may want to change the data fields used in a predefined template by adding and deleting fields. If you are using a blank template, you must add the data fields you want to use.Tip: You can select up to 1,500 DNIS entities per report. However, note that reports with more than 20 DNIS entities will take additional time to generate.If you generate a historical report on a large number of agents, the report may show the entire list of agents in the Agent Name field, but no data is displayed. In this instance, contact your system administrator. The administrator must add the value reduce_header_size=1 to the [Admin Configuration] section of the wecc.ini file on your PC.Before adding or deleting a field, view the description of the fields.
