Select with Appending

We can directly append records into an internal table with select statement by using APPENDING clause. Syntax is as follows.

SELECT db_field1, db_field2,…
  FROM db_table APPENDING TABLE internal_table
  WHERE db_field = condition.

Where is optional. By using APPENDING clause we can re-select and fetch another sort of records into the same internal table. Here the system appends the records to the last position of the internal table. After appending these records when we write the data then it will come one by one (not in the same row).

In below example at first we have selected PO number. So the system will append the PO numbers only. After that in the second select the system will select the materials and append those to the last position of the internal table and so on.

TYPES:
      BEGIN OF ty_ekpo,
        ebeln TYPE ekpo-ebeln,
        ebelp TYPE ekpo-ebelp,
        matnr TYPE ekpo-matnr,
        werks TYPE ekpo-werks,
        lgort TYPE ekpo-lgort,

DATA:

      it_ekpo TYPE STANDARD TABLE OF ty_ekpo.

REFRESH it_ekpo.

SELECT ebeln
  FROM ekpo APPENDING TABLE it_ekpo
  WHERE ebeln = '3000000232'.

SELECT matnr
  FROM ekpo APPENDING TABLE it_ekpo
  WHERE ebeln = '3000000232'.

SELECT werks
  FROM ekpo APPENDING TABLE it_ekpo
  WHERE ebeln = '3000000232'.

SELECT lgort
  FROM ekpo APPENDING TABLE it_ekpo
  WHERE ebeln = '3000000232'.

LOOP AT it_ekpo INTO wa_ekpo.
  WRITE:/    wa_ekpo-ebeln,
             wa_ekpo-matnr,
             wa_ekpo-werks,
             wa_ekpo-lgort.
ENDLOOP.

The output is like this. One by one record will come for same row information.

We can use CORRESPONDING FIELDS OF statement also.

SELECT db_field1, db_field2,…
  FROM db_table

  APPENDING CORRESPONDING FIELDS OF TABLE internal_table
  WHERE db_field = condition.

In this case the output will come with the corresponding fields. The system will put the respective data on the respective fields of the output screen. But the records will come one by one (different rows) rather the same row.
