Former Member — Wed, 12 Nov 2008 12:04:13 GMT

HI,

First internal table contains data like matnr, werks.

matnr werks

Ex: 1 cp01

second internal table contains data like vbeln ,matnr, open quantity.

vbeln matnr openquantity

1 1 20

2 1 30

4 1 50

third internal table contains data like matnr ,labst and insme from marc.

matnr labst insme

1 20 30

1 10 40

i need output in final internal table like

Please provide me best solution.

Thanks in advance,

use all entries or inner join concept...

create a final internal table with all the fields.

Fetch the records from first table

fetch the records froms econd table

fetch the records from third table

loop the first table

read second table with key as matnr

read third table with key as matnr

move all the entries to final table

end loop.

Hi,

Please use the below logic.

Loop at itab3 into Wa_itab3.

read table itab1 into wa_itab1 with key matnr = wa_itab3-matnr.

read table itab2 into wa_itab2 with key matnr = wa_itab3-matnr.

Write : wa_itab1-matnr,wa_itab1-werks,wa_itab2-openquantity,wa_itab3-labst,wa_itab1-insme.

endloop.

Regards,

Shan

hi,

try the following way.

sort the three internal tables by matnr.

as there may be multiple records loop is better to use



  loop at itab1.
    
    loop at itab2 where matnr = itab1-matnr.
      
      loop at itab3 where matnr = itab2-matnr.

      final-matnr = itab3-matnr.
      final-werks = itab1-werks.
      final-openqty = itab2-openqty.
      final-labst    = itab3-labst .
      final-insme = itab3-insme.
      collect final.                  " USE COLLECT STATEMNT

      endloop.
            
    endloop.
        
  endloop.

regards

Hi,

You can use the below logic.

Count the number of records for all the 3 internals tables. Whichever is having maximum number of records, loop at that internal table and read the other two tables with key as matnr.

As per your example 2nd internal table has more number of records. So

Loop at ITAB2 into WA_TAB2.

Move corresponding values of WA_TAB2 to Final workarea (WA_FINAL).

Read table ITAB1 into WA_TAB1 with key matnr = WA_TAB2-matnr.

If sy-subrc = 0.

Move corresponding values of WA_TAB1 to Final workarea (WA_FINAL).

Endif.

Read table ITAB3 into WA_TAB3 with key matnr = WA_TAB2-matnr.

If sy-subrc = 0.

Move corresponding values of WA_TAB3 to Final workarea (WA_FINAL).

Endif.

Append WA_FINAL to IT_FINAL.

Endloop.
