Reverting an Incorrect, Unreported Invoice in PIH Chain

An Invoice (B2C) was generated without a request for integration,
so it remains in the chain of PIH,
How can this invoice be reverted, as it is incorrect and has not been reported (the invoice not meant for integration)

@m.alnoursi could you please give an example why B2C invoice is generated but it is note meant for integration? Are these for out of scope transactions?
