User exit in bex query

Question

Hi Gurus,
I am not so good in abap so can anyone help me with the coding for the logic which i have mentioned below. I want to do it in EXIT_SAPMRSRU_001. This exit for th virtual characteristics.
Create TEMP table with temp field A , Temp field B
Get Field A,  pass it to temp A,
Do a search in TEMP-temp field A
if not found in temp A,  copy field to temp field A , assign temp B =1
if found in temp A, copy field to temp field A , assign temp B =0
Put the above logic in a loop until final record is read.

Answer 1

TYPES: BEGIN OF TY_TEMP,
       FIELD_A TYPE STRING,
       FIELD_B TYPE STRING,          
       END OF TY_TEMP.
DATA: T_TEMP TYPE STANDARD TABLE OF TY_TEMP.
FIELD-SYMBOLS: <FS_TEMP> LIKE LINE OF T_TEMP.
LOOP AT T_TEMP ASSIGNING <FS_TEMP>.
IF <FS_TEMP>-FIELD_A NE PARAM_A.
<FS_TEMP>-FIELD_A = PARAM_A.
<FS_TEMP>-FIELD_B = 1.
ELSE.
<FS_TEMP>-FIELD_A = PARAM_A.
<FS_TEMP>-FIELD_B = 0.
ENDIF.
MODIFY T_TEMP FROM <FS_TEMP>.
ENDLOOP.
Modify it, according to your needs...And next time, try the code yourself first -;)
