Question

Options

• APrice tables were not up to date
• BWhen the general ledger account assignment needs to be corrected
• CCreation of new billable item with new price
• DWhen address data needs to be corrected on an invoice
• EConsumption data measurement was too high

• A
  77% (33)
• D
  9% (4)
• E
  14% (6)

Explanation

Rerating becomes necessary when already-rated billable items must be re-processed due to errors or changes in the rating inputs - specifically incorrect price tables (A), wrong general ledger account assignments (B), or the need to apply a new price to a new billable item (C). These three scenarios all require the system to re-run the charging logic against corrected or new data to produce accurate financial results in Convergent Invoicing.

Why D is wrong: Correcting address data on an invoice is a master data or invoice layout issue - it is handled through invoice correction or reversal/rebilling, not through the rerating engine, since addresses don't affect the pricing calculation.

Why E is wrong: If raw consumption measurement data was too high, the error lies in the source metering data, not in the rating process itself. The corrected consumption would need to be re-imported and reprocessed from the start, which is a data correction workflow, not a rerating scenario.

Memory tip: Think of rerating as fixing the "math and money rules" - prices wrong (A), wrong account (B), new price needed (C). If the problem is about what's printed on the invoice (D) or how much was actually consumed (E), rerating is the wrong tool.
