ABAP_DESCRIPTION
The example shows the declaration of two internal tables
t_address_tab and company_tab , where t_address_tab is contained in company_tab . For this purpose t_address_tab is defined as the table type. The component addresses of the
company structure is declared with this type. The data type of
company is used as the row type for the tables company_tab and
company_sorted_tab .
The internal table is filled using the value operator VALUE .
A row from company_tab is assigned to the field symbol
fs using READ and its table-like component addresses is processed in a LOOP . The content of the row is assigned to the structure address . Since addresses is an index table, sy-tabix can be analyzed.
To change the content of the component street of a row of the inner table addresses , the index of the relevant row is determined using a READ statement and it is then used in MODIFY . To make the changes effective in the corresponding row of the outer hashed table as well, the key access of the MODIFY statement is used.
Finally, the hashed table is assigned a sorted table with the same row type. In this way, the entries are automatically sorted by the table key
name . However, the entries of the inner standard table are sorted using the SORT command.
