Append Line Statement Of Work For Free

Using collect and append statements in SAP ABAP, difference between append and collect. COLLECT is a statement which is similar to APPEND, the differences are : The COLLECT statement checks weather the work area record already exists with same key field value (the key field must be of type C, N, D, T).

To copy the records, we can use a SELECT statement to select all of the records from the table and then use MOVE statement that will move the records from the original table into the new internal table into the fields where the names correspond.

To add a line to an index table, use the statement: APPEND line TO itab. line is either a work area wa that is convertible to the line type, or the expression INITIAL LINE. If you use wa, the system adds a new line to the internal table itab and fills it with the contents of the work area.

The APPEND statement sets sy-tabix to the row number of the last appended row in the primary table index. Notes. The administration of a unique secondary table key is updated immediately; the administration of a non-unique key is not updated until the secondary table key is next used explicitly (lazy update).

APPEND line TO itab. line is either a work area wa that is convertible to the line type, or the expression INITIAL LINE. If you use wa, the system adds a new line to the internal table itab and fills it with the contents of the work area.

It is like a structure declaration in C. You can refer individual columns in the work area with the names. If you declare an internal table with "WITH HEADER LINE" clause the internal table itself acts as a work area. For example, your ITAB is a work area and ITAB is the internal table.
