應用場景：額度沖減

siebel中實現先占用后清除功能，需要清除前一次寫入的值。

if(quotaId != ""){with(bcQuota){SetViewMode(AllView);ActivateField("Id");ActivateField("Available Amount");ActivateField("Occupation Amount");ClearToQuery();searchExpr = "[Id] = '" + quotaId + "'";SetSearchExpr(searchExpr);ExecuteQuery(ForwardOnly);if(FirstRecord()){availAmount = ToNumber(GetFieldValue("Available Amount"));occupAmount = ToNumber(GetFieldValue("Occupation Amount"));//availAmount = availAmount + Math.abs(sumCSP-sumNRC);var minResult = Math.abs(sumCSP-sumNRC);if((occupAmount-minResult)< 0.0000001){//TheApplication().RaiseErrorText(occupAmount +"------" +minResult);occupAmount = 0;}else{occupAmount = occupAmount-minResult;}//SetFieldValue("Available Amount",availAmount);SetFieldValue("Occupation Amount",occupAmount);WriteRecord();}//end if}//end with }
