If rows are inserted before the current row, the internal loop counter is increased by one with each If rows are deleted after the current row, the deleted rows are no longer processed in the subsequent loop passes. If rows are inserted after the current row, these new rows are processed in the subsequent loop passes. In the case of loops on hashed tables and if using a hash key, the position depends on the insert order. The following effects: The position of inserted or deleted rows with respect to the current row is determinedīy the row numbers in the corresponding table index in the case of loops on index tables or if using a sorted key. If rows are inserted or deleted in the statement block of a LOOP, this has The system fields sy-tfill and sy-tleng are also filled. The loop using ENDLOOP, sy-tabix is set to the value that it had before entering the loop and that applies for sy-subrc: Sorted key on the row number of the current table row in the associated table index. In each loop pass for index tables and when using a This variant of the statement LOOP AT sets the value of the system field sy-tabix: 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 order used after the statement SORT. 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 specified after USING KEY, the order in which the rows are read depends on the table category as follows: Afterwards, it is no longer possible to access the internal table. Table expression, the value is persisted for the duration of the loop. If the internal table is specified as the return value or result of a ENDAT can be used to define control structures for Either all the rows are read or cond conditions are specified to restrict which rows are 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. Processing Statements for Internal Tables →ĪT itab executes the statement block between LOOP and ENDLOOP once for each read row. AS ABAP Release 753, ©Copyright 2019 SAP AG.
