InventoryWorker.getOutstandingProductQuantities returns inaccurate results when there are multiple ItemIssuances for an order
-----------------------------------------------------------------------------------------------------------------------------

                 Key: OFBIZ-4559
                 URL: https://issues.apache.org/jira/browse/OFBIZ-4559
             Project: OFBiz
          Issue Type: Bug
          Components: order
    Affects Versions: Release 10.04
            Reporter: Skip Dever
            Priority: Minor


If you create a purchase order for say 50 of an item, and then receive part of that order, say 10, and then receive another 10.  If you then call InventoryWorker.getOutstandingProductQuantities(), the OrderItemQuantityReportGroupByItem.quantityOpen will report 80.  This is because there will be two ItemIssuance records, resulting in 2 * 50 OrderItem.quantity minus the 20 ItemIssuance.quantity in the result set of the query.

I was able to verify this by creating a second view entity that can be viewed in WebTools

Here is the added view entity (essentially removing the group-by="false" values:

    <view-entity entity-name="OrderItemQuantityAndIssuance"
            package-name="org.ofbiz.order.order"
            never-cache="true"
            title="Reports quantity ordered, issued and open by item for OrderItems.">
      <member-entity entity-alias="OH" entity-name="OrderHeader"/>
      <member-entity entity-alias="OI" entity-name="OrderItem"/>
      <member-entity entity-alias="II" entity-name="ItemIssuance"/>
      <alias entity-alias="OH" name="orderTypeId" group-by="true"/>
      <alias entity-alias="OI" name="productId" group-by="true"/>
      <alias entity-alias="OI" name="quantityOrdered" function="sum">
          <complex-alias operator="-">
              <complex-alias-field entity-alias="OI" field="quantity" default-value="0"/>
              <complex-alias-field entity-alias="OI" field="cancelQuantity" default-value="0"/>
          </complex-alias>
      </alias>
      <alias entity-alias="II" name="quantityIssued" field="quantity" function="sum"/>
      <alias entity-alias="OI" name="quantityOpen" function="sum">
          <complex-alias operator="-">
              <complex-alias-field entity-alias="OI" field="quantity" default-value="0"/>
              <complex-alias-field entity-alias="OI" field="cancelQuantity" default-value="0"/>
              <complex-alias-field entity-alias="II" field="quantity" default-value="0"/>
          </complex-alias>
      </alias>
      <view-link entity-alias="OI" rel-entity-alias="OH">
        <key-map field-name="orderId"/>
      </view-link>
      <view-link entity-alias="OI" rel-entity-alias="II" rel-optional="true">
        <key-map field-name="orderId"/>
        <key-map field-name="orderItemSeqId"/>
      </view-link>
    </view-entity>


If you use this entity and find a purchase order with multiple item issuances, the problem will be apparent.
