Simple logic - virtual characteristic

Question

I'm writing a code for a virtual characteristic, but need a couple pieces to get in place. please help with the following problem:
In my logic, I have an internal table itab1 whose contents are as follows:
plant sale
1001 100
1001 50
2001 300
First I want to aggregate multiple rows like below:
plant sale
1001 150
2001 300
Second, I want to create another internal itab2 which ranks plants as follows:
plant sale rank
1001 150 2
2001 300 1
Please help with logic.

Answer 1

Hello,
1) When you select values in the internal table make you select statement as below;
select plant sum( sales ) as sales from table into corresponding fields of table itab1 group by plant.
This will give output as:
plant sale
1001 150
2001 300
2) For ranking, i believe you want them to be ranked based on the sales they have. For that do the foll:
data: count(3) type n.
itab2[] = itab1[].
sort itab2 descending by sales.
count = 1.
loop at itab2 into wa2.
wa1-rank = count.
modify itab2 from wa2.
count = count + 1.
endloop.
clear count.
