Boa tarde pessoal, estou com um sistema que comprei online.

Trata-se de um sistema online de gestão empresarial com pdv. Eu estou com uma dificuldade para alterar um dado que eu quero. Vou tentar explicar caso ainda haja dúvidas podem me perguntar.

É o seguinte:

Nome do sistema: Stock Manager PDV

1. Eu abro uma venda e nela tenho que selecionar o comprador, produto, quantidade e o valor ele puxa do estoque.

2.Porém quando eu tento alterar o valor unitário da venda, ele puxa do estoque, mas eu preciso alterar no pedido o valor do produto.

 

------------ CONTROLADORA DO PDV ------------

Será que alguém pode me ajudar?

Eu não sei aonde eu vou para que quando eu inicie a venda, eu possa editar o valor unitário do produto.

Olá amigo!

Primeiramente isso é errado. Você fazendo isso voce tira todo o sentido de controle de estoque, valor de custo e lucro. Provavelmente o sistema deve ter uma area financeira estatisticas e etc. alterando o valor do produto no pedido, toda vez que voce alterar voce altera no bd o valor do produto oque acaba sendo muito ruim para suas estatísticas. Se já não existir eu aconselho você a criar um campo de desconto direto no valor final para você poder alterar o valor final da venda e até poder mensurar qual a % de renda que voce tem alterado direto das vendas.
