Have the following effects: The position of inserted or deleted rows with regard to the current row If you insert or delete rows in the statement block of a LOOP, this will The system fields sy-tfill and sy-tleng are also filled. LOOP AT does not modify sy-subrc.Īfter leaving the loop using ENDLOOP, sy-tabix is set to the value that it had before entering the loop and that applies for sy-subrc: sy-subrc LOOP AT sets the value of the system field sy-tabix to the row number of the current row in the relevant table index. System Fieldsĭuring each loop run for index tables, and when you are using a If no appropriate rows are found or if the internal table is blank, the loop is not run at all. Have been read or until it is exited with a statement. The loop continues to run until all the table rows that meet the cond condition In each loop pass, the system field sy-tabix contains the value 0. In the table, and by the sort sequence with the SORT statement. The rows are processed in the order in which they were inserted In each loop pass, the system field sy-tabix contains the row number of the current row in the primary table index. The rows are read by ascending row numbers in the If no explicit table key name is declared after USING KEY, the order in which the rows are read depends on the table type as follows: To exit processing of the statement block, you can use the statements described in the The statement block between LOOP and ENDLOOP is executed once for each row. You can either read all the rows or specify cond conditions to restrict which rows to read. The table key with which the loop is executed can be determined in cond. The output response result determines how and to where the row contents are read.

The LOOP statement reads rows from the internal table itab sequentially. The LOOP and ENDLOOP statements define a loopĪround a statement block.

In here, the table has only one component TABLE_LINE. Example 1 – Reading table entry using the Key TABLE_LINE You must enjoy this when using the Deep structure reading. You can have multiple table expression chained together like.But lets discuss that in the next article. There are few exceptions when you don’t need to catch it. When table entry doesn’t exist, a catchable exception CX_SY_ITAB_LINE_NOT_FOUND is raised.

If you are still using the HEADER LINE, you would need to stop doing that and upgrade to more newer forms of Table definitions Don’t get confused with the table specification when you were using the HEADER LINE, e.g.Within the bracket, you would need to specify the component you want to use as the key. With using the Write Positions, you can read the data change the value directly. For Writing the data – This has same effect as the MODIFY statement on the table entry.

You can access the row in question directly by specifying the key. This would do the same job as you do with the READ statement, but without using the local variables.

For Reading the data – These are known as Reader Positions.
