sum fields in internal table

[Former Member]

Hi,

my sorted table with unique key field1 field2 is defined like:

field1 keyfield

field2 keyfield

field3

field4

i would like to get a sum of field3 and field4 of all entries "for each new field1 field2" and write it out.

field1 = 1

field2 = 100

sum(field3)

sum(field4)

write it out.

field1 = 1

field2 = 200

sum(field3)

sum(field4)

write it out.

field1 = 2

field2 = 100

sum(field3)

sum(field4)

write it out.

Q: Should I use LOOP and AT NEW FIELD1/FIELD2 or can i use another way for that ?

Thanks,

Gordon

Hi,

You can use loop and At new.it is enough.

Hi,

my sorted table with unique key field1 field2 is defined like:

field1 keyfield

field2 keyfield

field3

field4

create one more table similar to the above table

loop the first table.

secondtable-field1 = firsttable-field1.

secondtable-field2 = firsttable-field1

secondtable-field3 = firsttable-field1

secondtable-field4 = firsttable-field1

collect secondtable.

endloop.

declare an internal table same as itab...

first do a sort on internal table...

sort itab by field1 field2.

loop at itab.

itab1-field1 = itab-field1.

itab1-field2 = itab-field2.

itab1-field3 = itab-field3.

itab1-field4 = itab-field4.

collect itab1.

endloop.

loop at itab1.

write:/itab1-field1, itab1-field2, itab1-field3, itab1-field4.

endloop.

hi,

you will have to use LOOP AT and AT NEW field2.

[Former Member]

thanks for your help.

what is the better way to avoid performance issue.

1. loop / at new field or

2. second itab and use collect itab.

note: my table is selected from VBRP (invoice items) - very huge

Hi

The second option is to be avoided.

2. second itab and use collect itab.

if field1 and field2 are non numeric then

collect those values to other itab...

[Former Member]

they are both numeric.

[Former Member]

hi,

then you cannot use "collect" statement.

you will have to first sort table based on field1 field2.

then you will have to use LOOP AT and AT NEW field2.

[kesavadas_thekkillath]

Then do it like this.

loop at itab into wa.

at new field2.

move wa-field1 to it2-field1.

move wa-field2 to it2-field2.

endat.

at end of field2.

sum.

move wa-field3 to wa1-field3.

move wa-field4 to wa1-field4.

append wa1 to it2.

endat.

endloop.
