Hi Friend,
Make the following corrections.Your code will work fine.
By the statement- 'itab LIKE TABLE OF cond .' you meant to create a table of the type 'COND' which should be a structure.
So, here lies the problem.In your case COND is a char type variable and you are trying to mimic the table 'itab' from it.
As a rule of thumb,a table should mimic a std., table or a structure.
So remove the following lines:
data : cond(72) TYPE C,
itab LIKE TABLE OF cond .
Include the following lines:
type: begin og itab_record,
        cond(72) TYPE C,
        end of itab_record."Declaration of structure itab_record.
data: itab type standard table of itab_record initial size 0 with header line."Declaration of the table itab which mimics the       structure itab_record.
Modify these two statements,
cond = 'auart IN p_auart' .
APPEND cond To itab.
to
itab_record-cond = 'auart IN p_auart' .
append itab_record.
Other lines are exact,make these changes,execute it and seek my assistance if necessary.
