Transfer stock error

[Wenny]

I want to transfer Unrestricted-Use Stock from GS01 to Blocked Stock at GS02. When using the following field values, I received the error message:"Deficit of SL Stck.in qual.insp 1 PC : MPD241204BK24 GS00 GS01"
Here is my post body

{

    "PostingDate": "2024-09-05T00:00:00",

    "GoodsMovementCode": "04",  // Transfer Posting

    "to_MaterialDocumentItem": [

        {

            "Plant": "GS00",

            "StorageLocation": "GS01",

            "InventoryStockType": "01",

            "Material": "MPD241204BK24",

            "GoodsMovementType": "321",

            "QuantityInEntryUnit": "1",

            "IssuingOrReceivingPlant": "GS00",

            "IssuingOrReceivingStorageLoc": "GS02",

            "IssuingOrReceivingStockType": "03"

        }

    ]

}
How should I adjust the field values?

Please use Mvt 343 to move from blocked to unrestricted.

Mvt 321 can only be applied when deciding on inspection lot.
