HOW TO CREATE A FINAL INTERNAL TABLE FROM 8 OTHER INTERNAL TABLES

Question

I have around 8 internal tables and I need to merge all of them into one final internal table so that I need to pass the new internal table for ALV Grid display

Answer 1

Hi Balram,
Assuming that there are logical links (ie foreign key relationships) between each of these internal tables, on way is to do several loops controlled by a binary search.
eg. we have 2 tables:
types: begin of ty_makt,
            matnr  type matnr,
            maktx  type maktx,
          end of ty_makt.
types: begin of ty_mara,
            matnr  type matnr,
            bismt  type bismt,
          end fo ty_mara.
types: begin of ty_output,
            matnr  type matnr,
            bismt  type bismt,
            maktx  type maktx,
          end of ty_output.
data: tbl_mara type table of ty_mara with header line,
        tbl_makt type table of ty_makt with header line,
        tbl_putput type table of ty_output with header line.
sort tbl_makt by matnr.
loop at tbl_mara.
  read table tbl_makt with key matnr = tbl_mara-matnr binary search.
  if sy-subrc eq 0.
* build tbl_output here
  endif.
endloop.
Hope this helps.
Cheers,
Pat.
