create LOV from more than 1 table

Hi,

 HOW TO CREATE a LOV BASED ON MORE THAN 1 TABLE IN E business suite form  

for example this is my query :

SELECT DISTINCT 

  x_t_balance.DEFINITION_CODE ,

  x_t_balance.NATURAL_ACCOUNT_SEGMENT_VALUE,

  x_tb_def.name

FROM XLA_TRIAL_BALANCES x_t_balance,

  XLA_TB_DEFINITIONS_TL x_tb_def

WHERE x_t_balance.DEFINITION_CODE = x_tb_def.DEFINITION_CODE

is there is note or document to read

thanks
