Hi,

<b>1.Editing ALV Output:</b>

Try using this code, which will help u change the data of ur ALV grid at run time,

FORM edit_field USING w_edit TYPE any.

CLEAR w_field.

w_field-fieldname = 'APPLN'.

w_field-tabname = 'IT_SECOBJECTS'.

w_field-seltext_l = text-m01.

w_field-edit = w_edit.

w_field-input = 'X'.w_field-outputlen = '10'.

w_field-col_pos = 1.

append w_field to i_field.

clear w_field.

endform.

<b>2.Comparing Internal Tables:</b>

Like other data objects, you can use internal tables as operands in logical expressions.

.... <itab1> <operator> <itab2> ...

For <operator>, all the Operators such as EQ, =, NE, <>, ><, GE, >=, LE, <=, GT, >, LT, <, can be used .

If you are using internal tables with header lines, remember that the header line and the body of the table have the same name. If you want to address the body of the table in a comparison, you must place two brackets ([ ]) after the table name.

Hi,

comparing 2 internal tables.

Look at the below sample to code to compare the Internal tables

REPORT demo_int_tables_compare.

DATA: BEGIN OF line,

col1 TYPE i,

col2 TYPE i,

END OF line.

DATA: itab LIKE TABLE OF line,

jtab LIKE TABLE OF line.

DO 3 TIMES.

line-col1 = sy-index.

line-col2 = sy-index ** 2.

APPEND line TO itab.

ENDDO.

MOVE itab TO jtab.

line-col1 = 10. line-col2 = 20.

APPEND line TO itab.

IF itab GT jtab.

WRITE / 'ITAB GT JTAB'.

ENDIF.

APPEND line TO jtab.

IF itab EQ jtab.

WRITE / 'ITAB EQ JTAB'.

ENDIF.

line-col1 = 30. line-col2 = 80.

APPEND line TO itab.

IF jtab LE itab.

WRITE / 'JTAB LE ITAB'.

ENDIF.

line-col1 = 50. line-col2 = 60.

APPEND line TO jtab.

IF itab NE jtab.

WRITE / 'ITAB NE JTAB'.

ENDIF.

IF itab LT jtab.

WRITE / 'ITAB LT JTAB'.

ENDIF.
