no i can't do select where in s_field2 since i need to retrive the data from by p_bukrs only for later minipulation

Write like this ....

select data from ITAB_CHECK into INTERNAL_ITAB

LOOP at INTERNAL_ITAB

if INTERNAL_ITAB-FIELD2 in s_field2.

• write logic ...

else.

*write logic

endif.

ENDLOOP

but i am selecting

SELECT * FROM ITAB

WHERE bukrs EQ p_bukrs

and if i do a loop on itab

and compare loop-field2 NE select options

then there may be field in the itab that isn't on the selection screen

and this would give unnecessary message error

If you are only giving single values in select-optins(not range) try the following code.

Loop at s_field2 .

if s_field2-sign eq 'I'.

read table INTERNAL_ITAB into wa with key INTERNAL_ITAB-FIELD2 = s_field2-low.

if sy-subrc ne 0.

Error Message.

endif.

endif.

endloop.
