Alongside the statements for editing individual rows in internal tables, other statements can be used to address and modify the entire body of the table. Examples:
- All categories of assignments applying to whole internal tables
- Deleting the whole of an internal table using
- Operations in target ranges such as
SELECT INTO TABLE
These types of accesses to the table body cause problems by producing a loop across the internal table
Do not modify the entire table body in a loop
You cannot use a loop across an internal table to perform accesses to the table that modify the entire table body at once.
A modifying access to the entire table body usually produces a runtime error and at the very least unpredictable
program behavior. If this can be detected statically, a syntax error occurs within classes and also
LOOPs with a statically detectable secondary key when the table operations in question are used. Otherwise, the syntax check simply returns a warning for compatibility reasons.
