Use item GTIN as Input parameter for Sales Order Manager BSSV

Hi ,

We have a requirement to use item GTIN as input parameter for "processSalesOrder"  instead of JDE item number (item product ) , Below are the parameter that is available as input parameters for the item in the BSSV.

<product>

                   <item>

                     <!--Optional:-->

                     <itemCatalog></itemCatalog>

                     <!--Optional:-->

                     <itemCustomer></itemCustomer>

                     <!--Optional:-->

                     <itemDescription></itemDescription>

                     <!--Optional:-->

                     <itemFreeForm></itemFreeForm>

                     <!--Optional:-->

                     <itemId></itemId>

                     <!--Optional:-->

                     <itemProduct>100173</itemProduct>

                     <!--Optional:-->

                     <itemUOMPrimary></itemUOMPrimary>

                     <!--Optional:-->

                     <itemUOMSecondary></itemUOMSecondary>

                  </item>

In P4210 application it works if we input the cross reference item with a "#" ,  eg  #8806088336008 with the correct config , but this dosent work when called through the BSSV,
