Is there any user exit to uncheck the check box of 'Order Combination' in XD01.
Thanks & Regards
Its not possible with userexit but with a BADI : CUSTOMER_ADD_DATA
Go to se18-> enter CUSTOMER_ADD_DATA then click implementation and press create and give Z_CUSTOMER_ADD_DATA ..press enter.
then click on interface and double click on method :PRESET_VALUES_SAREA
place e_knvv-KZAZU = ' ' between method and method like below.
method IF_EX_CUSTOMER_ADD_DATA~PRESET_VALUES_SAREA. e_knvv-KZAZU = ' '. endmethod.
Then save and activate...your problem will get solved venkatram
