    Usually X<tablename> and Y<tablename> are used in change document management to determine records updated (Y is old values and X new ones). (Look at transaction SCDO)

    T<tablename is an internal table read from database and I<tablename> is an import table parameter of the same structure. <tablename> is an equivalent of <tablename> declared with statement TABLES and contains usually the "old" value.

    Look at exit documentation. start at [User Exits In Sales Document Processing|http://help.sap.com/saphelp_46c/helpdata/en/1c/f62c7dd435d1118b3f0060b03ca329/content.htm]

    In General xvbap will contain the current data

    Yvbap will have the old data(Before we change the data in the transaction). I do not have any idea about TVBAP and others...
