ID WHILE • WHILE ABAP Statement
WHILE Short Reference
ABAP_SYNTAX WHILE log_exp $[statement_block$] ENDWHILE.
What does it do? Conditional loop. The statements WHILE and ENDWHILE define a control structure that can contain a complete statement block statement_block . After WHILE, any logical expression log_exp can follow. The statement block is repeated as long as the logical expression is true, or until it is exited with one of the statements to exit loops. In particular, the statement EXIT is intended for exiting a loop completely. Within the statement block, the system field sy-index contains the number of previous loop passes, including the current pass. In nested loops, sy-index always refers to the current loop.
Latest notes:
If WHILE loops are used to construct values or fill internal tables, they can usually be expressed more elegantly using conditional iterations with FOR in constructor expressions. NON_V5_HINTS
A maximum runtime can be configured using the profile parameters rdisp/scheduler/prio_low/max_runtime , rdisp/scheduler/prio_normal/max_runtime, and rdisp/scheduler/prio_high/max_runtime . If this runtime is exceeded because the logical expression is never false and the loop is not exited in any other way, the program is terminated by the runtime framework.
The obsolete addition VARY can be used to process a sequence of data objects in the memory. ABAP_HINT_END
ABAP_EXAMPLE_VX5 Filling of an internal table with 100 lines. A FOR expression can now also be used for that purpose. ABEXA 00765 ABAP_EXAMPLE_END
