Acumatica 如何在处理表单中传递用户定义字段

Question

我想在标记为 PO（采购到订单）的销售订单中填写采购订单中的 2 个字段（一个来自 SOOrderExt，第二个来自 SOLineExt）。 如何使用处理表格“创建采购订单”(PO.50.50.00) 来执行此操作

Answer 1

您需要覆盖

FindOrCreatePOOrder

图表上的

FindOrCreatePOLine

和

POCreate

。 在

FindOrCreatePOOrder

中，新的poOrder还没有在缓存中，它只是一个简单的对象，所以你无法获取它的扩展名。您必须在

FindOrCreatePOLine

中为您的新采购订单设置代理。
