API call for creation of a delivery.

Since pixi version: LOU Official (6.3.0.4452) Additional notes: API call creates a new delivery header for a specified supplier. ----------------------------------------------------------------

     - There are **3** possible scenarios for creating the delivery.
    
    **Create an empty delivery document:**
    
     - Only the delivery header will be created. 
     - To add the items/delivery lines api call **pixiCreateDeliveryItem** can be used.
     - Sample request:
    
    	    <soapenv:Envelope>
    			<soapenv:Header/>
    			<soapenv:Body>
    				<pix:pixiCreateDelivery>
    					<pix:LocID>001</pix:LocID>
    					<pix:SupplNr>MGS</pix:SupplNr>
    					<pix:UserName>Max</pix:UserName>
    					<pix:Note>Empty delivery</pix:Note>
    				</pix:pixiCreateDelivery>
    			</soapenv:Body>
    		</soapenv:Envelope>
    
    **Create a delivery using supplier order as template:**
    
     - The delivery will be created based on selected supplier order number.
     - The items and their ordered quantities will be transferred to the delivery document from supplier order. 
     - To set the delivered item quantities API call **pixiUpdateDeliveryItem** can be used. 
     - Sample request:
       
    		<soapenv:Envelope>
    			<soapenv:Header/>
    			<soapenv:Body>
    				<pix:pixiCreateDelivery>         
    					<pix:OrderNr>1025547</pix:OrderNr>         
    					<pix:UserName>Max</pix:UserName>       
    					<pix:Note>Delivery from template using supplier order 1025547</pix:Note>  
    				</pix:pixiCreateDelivery>
    			</soapenv:Body>
    		</soapenv:Envelope>
    
    **Create a new delivery document with corresponding items/delivery lines:**
    
     - This can be achieved using the **ParameterXML** parameter. 
     - To prevent confusion its best to provide all the parameters in the XML and leave other parameters empty.
     - Sample request:
    
    	    <soapenv:Envelope>
    		<soapenv:Header/>
    		<soapenv:Body>
    			<pix:pixiCreateDelivery>
    				<pix:ParameterXML>
    					<![CDATA[<CREATE_DELIVERY>
    						<Delivery>
    							<LocID>001</LocID> 		
    							<SupplNr>Bush</SupplNr>							
    							<SupplOrderNrExt/>
    							<Username>Max</Username> 
    							<Note>New delivery with items/ delivery lines</Note>
    							<ITEMS>  
    								<Item>
    									<EAN/>
    									<ItemNrSuppl/>
    									<ItemNrInt>442fccba2d05dfc0df03ff8a872ecd4c</ItemNrInt> 
    									<Ordered>10</Ordered> 
    									<Delivered>2</Delivered> 				
    									<SupplPrice>4.87</SupplPrice> 
    								</Item> 
    								<Item>
    									<EAN/>
    									<ItemNrSuppl/>
    									<ItemNrInt>442fccba2d05dfc0df03ff8a872ecd4c</ItemNrInt> 
    									<Ordered>10</Ordered> 
    									<Delivered>2</Delivered> 				
    									<SupplPrice>4.98</SupplPrice>
                                        <InternalNumber>70010513</InternalNumber>
                                        <ExternalCode>ExCode_13-333</ExternalCode>
    								</Item>
    							</ITEMS> 
    						</Delivery>
    					</CREATE_DELIVERY>]]>
    				</pix:ParameterXML>
    			</pix:pixiCreateDelivery>
    		</soapenv:Body>
    		</soapenv:Envelope>
    
    **Important:**
    
     - When InternalNumber and ExternalCode are sent, we consider only InternalNumber.
     - When ExternalCode exists on multiple Purchase Orders we return an error.
     - Only items that belong to a specified supplier will be added to the delivery lines.
     - When **OrderNr** parameter is specified item details will automaticaly be taken from the supplier order template. To update the deliverd quantity for items API call pixiUpdateDeliveryItem can be used.
     - When creating delivery using ParameterXML it is also possible to set BatchNumber and BestBeforeDate for items
     - Partial XML sample:
    
    		<Item>
    			<EAN/>
    			<ItemNrSuppl/>
    			<ItemNrInt>442fccba2d05dfc0df03ff8a872ecd4c</ItemNrInt> 
    			<Ordered>10</Ordered> 
    			<Delivered>2</Delivered> 				
    			<SupplPrice>4</SupplPrice>
    			<BatchNumber>BatchTest</BatchNumber>
    			<BestBeforeDate>01.01.2019</BestBeforeDate>  
                <InternalNumber>70010513</InternalNumber>
                <ExternalCode>ExCode_13-333</ExternalCode>
    		</Item>
