    SQL transaction Error

    I am receiving this error message when running the code below

    'The transaction associated with the current connection has completed but has not been disposed. The transaction must be disposed before the connection can be used to execute SQL statements.' occurred when attempting to 'Execute query'


    Code:
    #region Export_Admissions
    
    	[Promote(PromotionTargets.All)]
        [Category("Export")]
        public static void Export_TONAdmissions(EXPORT_TON_Admissions1 myData,TON_Export_Import.Declarations.TON_Export_ImportData LocalData)
