What are Billing Parameters?
Billing parameters establish the billing method, ceiling, tolerance, and other processing criteria for an activity.
You can define billing parameters for a summary/contract level activity or a posting level activity. Parameters defined for a summary/contract level activity apply to all activities under the summary/contract activity.
Define billing parameters at the highest level possible to simplify data entry. You can override parameters at any lower level, including the posting level or the account category level.
