Diagnosis
The data to be processed was transferred to internal retroactivebilling, which returned a net value of 0. This could be due to an errorin pricing or a missing price condition for the pricing key date.

System Response
There is no further processing when the returned net value is 0.

Procedure
You can either maintain the price conditions such that the returned netvalue is greater than 0 or exclude the data record from furtherprocessing by deactivating it.
As long as retroactive billing returns a net value of 0, processingcannot be continued.
