Boa Tarde,
Conforme SAP Note 1376351 :
"In Customizing path "SAP Customizing Implementation Guide -> Materials Management -> Logistics Invoice Verification -> Incoming Invoice -> Number Assignment -> Maintain Number Assignments for Accounting Documents", maintain the revaluation document type for transaction code MRRL (or MRDC as of Release 6.00).
The selected document type "Document Type Revaluation" must have an internal number assignment and it must not be the same as the document type for the invoice receipt."
No meu entendimento, você deve ter um range interno que não pode ser o mesmo das faturas recebidas.
Faça essa configuração e teste novamente.
Valeu,
