Reg: VA01 sales order going to dump

Dear all,

In our develpment server(ecc 6.0),while creating sales order in VA01 for a sales area, when ever entering material number(variant configuration material) and quantity and press enter, it is giving runtime error as i shown below.

The following syntax error occurred in program

"CL_LORD_OBJECT================CP " in include

"CL_LORD_OBJECT================CM005 " in

line 40:

""OBJECT-" expected, not "IF_OBJECT_""

method class_constructor.

• Register to event CHANGED of all LORD object instances

set handler on_lord_object_changed for all instances activation 'X'.----

• Register to event AUART_CHANGED of all LORD header instances

set handler on_lord_auart_changed for all instances activation 'X'.

endmethod.

can any one guide me in this issue
