    ----------
    
    XML tags used for **identifying the item**:
    
     - **EANUPC** -- Item barcode (Only EANUPC from ITEMS (current supplier) can be used. The recommendation is to use some other item code/itemkey that is unique for the item.)
     - **ITEMNRINT** -- Shop item number 
     - **ITEMKEY** -- pixi* item ID
     - **BATCHNUMBER** -- Item batch number (mandatory when the item has tag "BN")
     - **BESTBEFOREDATE** -- Item best before date (mandatory when the item has tag "BBD")
    
    XML tags for performing the **stock operations**:
    
     - **BINNAME** - Bin name
     - **STOCKADD** - Add the stock for selected item on selected bin
     - **STOCKREMOVE** - Remove the stock for selected item on selected bin
     - **SMTREF** - Stock movement type ID
     - **SMOREF** - Stock movement operation ID
    
    XML tags to be used with **extreme caution**:
    
     - **OVERWRITESTOCK** - Stock for selected item will be removed from all bins (0/1)
     - **NEUTRALINVENTORY** - deprecated from pixi* ELI on
     - ! **STOCK** ! - Set stock for selected item on selected bin to this exact number
    	 - *Important*: As this tag might cause issues, we do not recommend using it at all! Instead, use STOCKADD or STOCKREMOVE.
    
    
    *Important*: If same Bin name exists on two or more locations, do not use this API, since it will produce strange results with such Bins.
