Definition Easy Bill-correction Framework
The Easy Bill-correction Framework (EBF) is a tool box for simple corrections /re-calculations of billing document lines comes from an non-operationaldatabase, without any installation structure.
EBF is able to:migrated billing documents from the legacy system in an non-operationalcustomer databaseuse customer-specific correction methods on line item levelcreate a manual billing document for single corrections on easy way
EBF is not able to:create a manual billing document from the operational IS-U databasehandle any installation-structures or facts
In the end EBF is a more automatic way to create a manual billing documentwith reduced information.
