Falta RSExecRole

Abra "Reporting Services Configuration Manager" --> Banco de dados, verifique se o login em [Current Report Server Database Credential] é um dos usuários no RSExecRole ou não, caso contrário, clique no botão "Change Credentials" para mudar para um usuário no RSExecRole.

Você também pode usar o utilitário de linha de comando rsconfig http://technet.microsoft.com/en-us/library/ms162837.aspx

Já que você também queria o código, eu criei um script para você...

Edit: Eu editei, então abaixo fica o código completo.

• Alguém pode me ajudar com um roteiro?

Claro! Execute o SQL Profiler, crie um novo banco de dados ReportServer usando o 'Reporting Services Configuration Manager' (você pode especificar seu próprio nome para evitar colisões) e capture todas as instruções. O script final depende da versão e edição do sql, portanto não é genérico e não deve ser reutilizado. É bom para educação (por exemplo, dependências RSExecRole) e nada mais.

• Alguém já encontrou esse problema antes?

Já vi tentativas de script de todos os objetos ReportServer. Pode parecer bom, mas é uma má ideia - muito fácil perder algo importante (RSExecRole). Bancos de dados de terceiros (Reporting Services, ASPState, etc.) devem ser criados e configurados com ferramentas dedicadas. Outra explicação - alguém abandonou explicitamente esse papel.
