Não insere novo documento

A base utiliza nf manual por controle especifico, as entredas ocorreram normalmente ate chegar ao nº 500.

Depois disso o sistema me impede de inserir qualquer nota na sequência.

Ao tentar inserir a 500 recebo a mensagem de

Nº de nota fiscal já foi utilizado

Sabendo que o doc não existe tentei inserir um na sequencia e recebi a resposta de

Esta entrada já existe nas tabelas seguintes " (INV1)(ODBC -2035)

Eu realizei essa consulta tentado procurar qualquer doc com o a numeração, mas não encontrei nada.
