If your declaration of the table includes WITH HEADER LINE, just use tablename-variablename assignments and then APPEND or MODIFY tablename.

If it doesn't, declare a variable of the same type as the table structure (this is called WorkArea) and assign values using workareaname-variablename and when you are done APPEND or MODIFY tablename , with APPEND wornareaname INTO tablename.

Hi, it is impossible to use append with hashed table because it is index operation. Use insert.

INSERT wa_line INTO gt_table.

Hi,

try this way-

DATA:Itab like sorted table of sflight.

wa like line of itab.

wa-carrid = 'AA'.

wa-connid = '017'.

Append wa to itab.

Clear wa.

wa-carrid = 'AB'.

wa-connid = '012'.

Append wa to itab.

As you have declared internal table as sorted so when you insert data you have to maintain sorting order.

No, as I wrote you before, you cannot access hashed tables via indexes.

INSERT wa_data INTO gt_data.

of course, you can also select data into hashed tables from DB, or you can use COLECT....
