生产领料的问题

关于生产领料的超领,系统逻辑大概是这样的,如果生产BOM的已发放数量超过了Max(估计数量，开始的数量),如果在新建一笔领料,在建一笔退料(退料数量如果小于超过已放数量超过的那一部分)系统就会报这个错，根据代码的逻辑也是这样判断的,系统认为你已经发超了,会尝试清除你当前生产BOM的剩余数量,但是如果你还有在单的领料,退料时,系统就会判断,你当前已发超的数量-需要退的数量>0,系统就要求你必须先处理这笔领料。如下图：

已发放数量已经超过MAX(估计,已开始)

建一笔领料数量20和和两笔退料数量分别是10和30。

图一：数量为20的领料

图二：数量为10的退料,无法正常过账

图三：数量为30 的退料,能正常过账

解决办法

1:遇到这种情况,让用户主动去清除这笔在单的领料(这样估计客户很难接受)

2:用户不能接受,那就只能去修改代码了

具体修改地方有ProdJournalBOM表里的两个计算剩余数方法

InventQty  calcRemainInventPhysical(ProdBOM  prodBOM)
{
    InventQty   inventRemain;
    InventQty   remainInventFinancial;
 
    if (! prodBOM.RecId)
        prodBOM = ProdBOM::findTransId(this.InventTransId);
 
    if (!this.InventReturnFlag)
    {
        inventRemain = prodBOM.RemainInventPhysical - this.InventConsump;
 
        if  (inventRemain* prodBOM.RemainInventPhysical <= 0)
            inventRemain = 0;
    }
    else
    {
        inventRemain = 0;
 
        if (prodBOM.QtyInventCalc && ! prodBOM.isReportedAsFinished())
        {
            remainInventFinancial = prodBOM.remainInventFinancial();
            if (abs(remainInventFinancial + this.InventConsump) < abs(prodBOM.maxQtyCalcStUpInvent()))
            {
                inventRemain = prodBOM.maxQtyCalcStUpInvent() - remainInventFinancial - this.InventConsump;
                if (abs(inventRemain) < abs(prodBOM.RemainInventPhysical))
                    inventRemain = prodBOM.RemainInventPhysical;
            }
            //by kim 140319 start
            else
                inventRemain    = prodBOM.RemainInventPhysical;
            //by kim 140319 end
        }
        //by kim 140319 start
        if (prodBOM.QtyInventCalc && prodBOM.isReportedAsFinished())
        {
            remainInventFinancial = prodBOM.remainInventFinancial();
            if (abs(remainInventFinancial + this.InventConsump) < abs(prodBOM.maxQtyCalcStUpInvent()))
            {
                inventRemain = prodBOM.maxQtyCalcStUpInvent() - remainInventFinancial - this.InventConsump;
                if (abs(inventRemain) < abs(prodBOM.RemainInventPhysical))
                    inventRemain = prodBOM.RemainInventPhysical;
            }
            else
                inventRemain    = prodBOM.RemainInventPhysical;
        }
        //by kim 140319 end
 
    }
 
    return inventRemain;
}

UnitQty     calcRemainBOMPhysical(ProdBOM  prodBOM)
{
    UnitQty         bomRemain;
 
    if (! prodBOM.RecId)
        prodBOM  = ProdBOM::findTransId(this.InventTransId);
 
    if (!this.InventReturnFlag)
    {
        bomRemain   = prodBOM.RemainBOMPhysical  - this.bomConsump;
 
        if (bomRemain* prodBOM.RemainBOMPhysical <= 0)
            bomRemain = 0;
    }
    else
    {
        bomRemain = 0;
 
        if (prodBOM.QtyBOMCalc && ! prodBOM.isReportedAsFinished())
        {
            if (abs(prodBOM.RemainBOMFinancial + this.bomConsump) < abs(prodBOM.maxQtyCalcStUpBOM()))
            {
                bomRemain = prodBOM.maxQtyCalcStUpBOM() - prodBOM.RemainBOMFinancial - this.bomConsump;
                if (abs(bomRemain) < abs(prodBOM.RemainBOMPhysical))
                    bomRemain = prodBOM.RemainBOMPhysical;
            }
            //by kim 140319 start
            else
                bomRemain    = prodBOM.RemainBOMPhysical;
            //by kim 140319 end
        }
        //by kim 140319 start
        if(prodBOM.QtyBOMCalc && prodBOM.isReportedAsFinished())
        {
            if (abs(prodBOM.RemainBOMFinancial + this.bomConsump) < abs(prodBOM.maxQtyCalcStUpBOM()))
            {
                bomRemain = prodBOM.maxQtyCalcStUpBOM() - prodBOM.RemainBOMFinancial - this.bomConsump;
                if (abs(bomRemain) < abs(prodBOM.RemainBOMPhysical))
                    bomRemain = prodBOM.RemainBOMPhysical;
            }
 
            else
                bomRemain    = prodBOM.RemainBOMPhysical;
        }
        //by kim 140319 end
    }
 
    return bomRemain;
}

　　最后是InventMovement的setPreTransEstimated方法

void setPreTransEstimated(InventMovement        this_Orig,
                         InventUpd_Estimated   updateNow)
{
 
    InventQty  preEstimated;
    InventQty  transEstimated;
    InventQty  sumQty;//by kim 140410
 
    if (! this_Orig)
    {
        preEstimated = 0;
 
        if (this.mustBeUpdatedExpected())
            transEstimated= this.remainPhysical();
        else
            transEstimated= 0;
 
    }
    else
    {
        if (! this.mustBeUpdatedExpected() && ! this_Orig.mustBeUpdatedExpected())
        {
            preEstimated  = 0;
            transEstimated= 0;
        }
        else
        if (! this.mustBeUpdatedExpected() && this_Orig.mustBeUpdatedExpected())
        {
            preEstimated  = this_Orig.remainPhysical();
            transEstimated= 0;
        }
        else
        if (this.mustBeUpdatedExpected() &&   ! this_Orig.mustBeUpdatedExpected())
        {
            preEstimated  = 0;
            transEstimated= this.remainPhysical();
        }
        else
        {
            //by kim 140319 start
            preEstimated    = this_Orig.remainPhysical();
            if(classidget(this_Orig) == classnum(InventMov_ProdLine))
            {
                if(abs(this_Orig.remainPhysical()) > 0  &&
                  abs(this.IWS_remainFinancial()) > max(abs(this_Orig.IWS_prodBOM().QtyBOMStUp),abs(this_Orig.IWS_prodBOM().QtyBOMCalc)))
                    preEstimated  = 0;
            }
            transEstimated  = this.remainPhysical();
            //by kim 140319 end
        }
    }
 
    if (this_Orig && this_Orig.mayScrapBeExpected() && this_Orig.doScrap())
    {
        preEstimated   = 0;
    }
 
    if (this.mayScrapBeExpected() && this.doScrap())
    {
        transEstimated = 0;
    }
 
    updateNow.parmPreEstimated(preEstimated);
    updateNow.parmTransEstimated(transEstimated);
 
}
