一、【需求问题】

组装拆卸时，按BOM展开后，物料清单中货主类型为客户的子项物料没有携带到组装拆卸单上，当前携带的是成品表的货主类型。 

二、【功能分析】

组装拆卸单的表单插件，对BOM展开的触发操作，将当前BOM展开后子件的货主类型和货主默认赋值为成品表的货主类型和货主，并没有采用清单上设置的子项物料货主类型和货主

当前标准插件无法禁用，只能是二开插件在BOM操作触发后，再获取到BOM子项的信息，将展开后的子件物料数据中货主类型和货主重新做赋值。

之前对于组装拆卸单的二开帖子参考:

1、组装拆卸单BOM展开，成品表仓库仓位赋值到子件表仓库仓位

2、Python继承AbstractValidator实现校验器案例 

核心代码Py:

def AfterEntryBarItemClick(e):
    if e.BarItemKey.Equals("TBBOMEXPAND", StringComparison.OrdinalIgnoreCase):

        formMetaData = metaService.Load(this.Context, "ENG_BOM")
        products = this.View.Model.DataObject["ProductEntity"]
        for i in range (0, products.Count):
            refBomID = Convert.ToInt64(products[i]["RefBomID_Id"])
            if refBomID == 0:
                continue
                
            bomObj = viewService.LoadSingle(this.Context, refBomID, formMetaData.BusinessInfo.GetDynamicObjectType())

                continue

                        this.Model.SetValue("FOwnerIDSETY", Convert.ToInt64(dySub[0]["OWNERID_Id"]), j);

C#：

public override void AfterEntryBarItemClick(AfterBarItemClickEventArgs e)
{
    switch (e.BarItemKey.ToUpperInvariant())
    {
        case "TBBOMEXPAND":
            this.BomExpand();
            break;
    }
}

private void BomExpand()
{
    IViewService viewService = SCM.Contracts.ServiceFactory.GetService<IViewService>(this.Context);
    IMetaDataService metaService = Kingdee.BOS.Contracts.ServiceFactory.GetService<IMetaDataService>(this.Context);
    FormMetadata formMetaData = (FormMetadata)metaService.Load(this.Context, "ENG_BOM");
    List<object> list = new List<object>();
    DynamicObjectCollection dataCollection = this.View.Model.DataObject["ProductEntity"] as DynamicObjectCollection;

	foreach(DynamicObject product in dataCollection)
    {
        long refBomID = Convert.ToInt64(product["RefBomID_Id"]);
        if (refBomID == 0) continue;
        DynamicObject bomObj = viewService.LoadSingle(this.Context, refBomID, formMetaData.BusinessInfo.GetDynamicObjectType());
        if (bomObj == null) continue;

        DynamicObjectCollection subItems = product["STK_ASSEMBLYSUBITEM"] as DynamicObjectCollection;
        DynamicObjectCollection bomTreeEntity = bomObj["TreeEntity"] as DynamicObjectCollection;
        foreach (var subItem in subItems)
        {
            long materialId = Convert.ToInt64(subItem["MaterialIDSETY_Id"]);
            DynamicObject dySub = bomTreeEntity.FirstOrDefault(p => Convert.ToInt64(p["MATERIALIDCHILD_Id"]) == materialId);
            if (dySub != null)
            {
                if(Convert.ToString(dySub["OWNERTYPEID"]) == "BD_Customer")
                {
                    subItem["OwnerTypeIDSETY"] = dySub["OWNERTYPEID"];
                    subItem["FOwnerIDSETY"] = dySub["OWNERID_Id"];
                }
            }
        }
    }
}

实现效果：

BOM展开子件货主类型携带自物料清单上子项物料的货主类型设置.rar
