Try following :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            DataTable targetTable = new DataTable();
            targetTable.Columns.Add("ID", typeof(int));
            targetTable.Columns.Add("Category Name", typeof(string));
            targetTable.Columns.Add("Target", typeof(int));

            targetTable.Rows.Add(new object[] { 1, "AAAA", 150000 });
            targetTable.Rows.Add(new object[] { 2, "BBBB", 500000 });
            targetTable.Rows.Add(new object[] { 3, "CCCC", 20000 });
            targetTable.Rows.Add(new object[] { 4, "DDDD", 40000 });
            targetTable.Rows.Add(new object[] { 5, "EEEE", 30000 });

            DataTable salesTable = new DataTable();
            salesTable.Columns.Add("ID", typeof(int));
            salesTable.Columns.Add("Date", typeof(DateTime));
            salesTable.Columns.Add("Category Name", typeof(string));
            salesTable.Columns.Add("Sale", typeof(int));

            salesTable.Rows.Add(new object[] { 1, DateTime.Parse("01/01/20"), "AAAA", 5000 });
            salesTable.Rows.Add(new object[] { 2, DateTime.Parse("01/01/20"), "BBBB", 1000 });
            salesTable.Rows.Add(new object[] { 3, DateTime.Parse("02/01/20"), "CCCC", 2000 });
            salesTable.Rows.Add(new object[] { 4, DateTime.Parse("03/01/20"), "DDDD", 4000 });
            salesTable.Rows.Add(new object[] { 5, DateTime.Parse("03/01/20"), "EEEE", 3000 });
            salesTable.Rows.Add(new object[] { 6, DateTime.Parse("03/01/20"), "AAAA", 1000 });
            salesTable.Rows.Add(new object[] { 7, DateTime.Parse("05/01/20"), "EEEE", 3000 });
            salesTable.Rows.Add(new object[] { 8, DateTime.Parse("06/01/20"), "BBBB", 3000 });
            salesTable.Rows.Add(new object[] { 9, DateTime.Parse("02/01/20"), "CCCC", 1000 });
            salesTable.Rows.Add(new object[] { 10, DateTime.Parse("02/01/20"), "DDDD", 2000 });

            DataTable table = new DataTable();
            table.Columns.Add("Target", typeof(int));
            table.Columns.Add("Category Name", typeof(string));
            table.Columns.Add("Sale", typeof(int));


            var joins = from t in targetTable.AsEnumerable()
                   join s in salesTable.AsEnumerable() on t.Field<string>("Category Name") equals s.Field<string>("Category Name")
                   select new { t = t, s = s};

            var groups = joins.GroupBy(x => x.t.Field<string>("Category Name"));

            foreach (var group in groups)
            {
                table.Rows.Add(new object[] { group.First().t.Field<int>("Target"), group.Key, group.Sum(x => x.s.Field<int>("Sale")) });
            }                                           
        }
    }
}

Answer 2

You may follow the tutorial how to create a devexpress report

and when you will create a query for the sql datasource, specify a grouping and aggregate the Target column using Sum function like

select Target.Target, sum(Sales.Sale)
from Target
join Sales ...
group by Target.Target

And you can Also create two queries for the report to produce the master-detail report layout, group & sum your Targets using the reporting summary mechanism so it will give you possibility to add a drill down feature to your report to view detailed reports.
