axapta - SysTableLookup 的查找方法错误？

Question

此代码应适用于添加到 Tables\ProdBOM 的任何基本系统。查询以某种方式从字段中剥离数据。

static void lookupItemIdBOMSubset(FormStringControl   _ctrl,
                                  ProdId              _prodId)
{
    SysTableLookup          sysTableLookup  = SysTableLookup::newParameters(tableNum(ProdBOM), _ctrl);
    Query                   query           = new Query();
    QueryBuildDataSource    qbds            = query.addDataSource(tableNum(ProdBOM));
    ;

    qbds.addRange(fieldNum(ProdBOM, ProdId)).value(queryvalue(_prodId));
    qbds.addSortField(fieldNum(ProdBOM, LineNum), SortOrder::Ascending);

    sysTableLookup.parmQuery(query);

    sysTableLookup.addLookupfield(fieldNum(ProdBOM, LineNum));
    sysTableLookup.addLookupfield(fieldNum(ProdBOM, BOMId));
    sysTableLookup.addLookupfield(fieldNum(ProdBOM, ItemId), true);

    // This doesn't work \/
    sysTableLookup.addLookupMethod(tablemethodstr(ProdBOM, configId));
    // This doesn't work /\

    sysTableLookup.addLookupMethod(tablemethodstr(ProdBOM, itemName));
    sysTableLookup.addLookupfield(fieldNum(ProdBOM, ProdLineType));
    sysTableLookup.addLookupfield(fieldNum(ProdBOM, InventTransId));

    sysTableLookup.performFormLookup();
}

在 Tables\ProdBOM\Methods\configId 中，您可以清楚地看到这段代码有问题。怎么回事？？

//BP Deviation documented
display ConfigId configId()
{
    ProdBOM pb;
    ;
    select firstonly pb where pb.RecId == this.RecId;

    info(strfmt("Bad: [%1, %2], Good:[%3, %4]", this.ItemId, this.InventDimId, pb.ItemId, pb.InventDimId));
    return this.inventDim().ConfigId;
}

Answer 1

所以我想通了。在 Classes\SysTableLookup\buildSelectionList 中，它将查找字段中包含的所有字段添加到 QBDS.addSelectionField，这似乎将其从返回字段中删除？？

虽然它没有去除 RecId，所以我能够创建另一种显示方法，使用 recId 重新选择记录。

//BP Deviation documented
display ConfigId configIdFromRecId()
{
    return InventDim::find((select firstonly prodBOM where prodBOM.RecId == this.RecId).InventDimId).configId;
}
