Assuntos Gerais
#1

Olá ,

não sei se o erro está que a coluna do join entre as duas colunas é a a mesma

nrnota tanto na tabela NotaFiscal e Nota FiscalItem…

Pois o Pai (NotaFiscal) ao ser gerado vai passar esse nrnota para o filho(NotaFiscalItem)

mas não consigo fazer isso automatico …

alguém poderia me ajudar abs
