As the three fields XREF1/2/3 are already included in structure ACGL_ITEM as SAP standard fields, you should follow carefully the instructions of the note 174413.
which states as follows..
To include customer-specific fields, proceed as follows.
1.  Include structure CI_COBL, which contains the customer fields, as an
     Include in structure ACGL_ITEM.
     Attention: If you have maintained foreign key dependencies for your
     customer fields, then copy structure CI_COBL into structure CI_ACGL
     and include it in structure ACGL_ITEM instead of structure CI_COBL.
     Adjust the foreign key checks in structure CI_ACGL so that you ony
     use fields of structure ACGL_ITEM as foreign key fields.
2.  Place the customer fields on screen SAPLFSKB 0100 (Transaction
     SE51).
3.  Enter '001' in Mod. group 4 for the added customer fields in the
                                                                   Page 2
     element list of the screen, and in Mod. group 1 fill the value from
     TCOBF-GROUP1 of the respective field.
4.  Transfer the fields to the flow logic of this screen. For every
     field, insert a FIELD statement between each of the two
     CHAIN/ENDCHAIN statements.
5.  In routine MOVE_ACGL_ITEM in Include LFSKBF01, insert a statement
     such as ACGL_ITEM-ZFIELD = *ACGL_ITEM-ZFIELD for every customer
     field (example ZFIELD).
6.  Generate or activate all objects.
7.  To take the new fields in the entry variants into account, choose
     'Create entry variant' via the menu. You can then take the customer
     fields into account when creating the new entry variant.
To include SAP standard fields that exist in structure ACGL_ITEM,
