SAP Error Message - Details

• Message text: Use a more exact statement structure: &1

What causes this issue?

In the new ABAP Debugger, breakpoints can be set at statements (e.g.
breakpoint at WRITE).
It is particularly important for statements that are used in Open SQL
and for internal tables, that you use the following variants to specify
whether you want to stop, for example at a MODIFY that relates to an
internal table, or one that relates to a database table:

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Statement Database Internal Table
MODIFY MODIFY dbtab MODIFY itab
DELETE DELETE dbtab DELETE itab
INSERT INSERT dbtab INSERT itab
READ READ dbtab(obsolet) READ TABLE
UPDATE UPDATE -
SELECT SELECT -
LOOP LOOP AT ITAB
SORT SORT ITAB
APPEND - APPEND
Furthermore, the various EXPORT/IMPORT variants
can be differentiated in terms of the target medium:
EXPORT TO MEMORY, EXPORT TO DATABASE, EXPORT TO SHARED MEMORY, EXPORT TO
SHARED BUFFER - (Identical for IMPORT).
In the breakpoint/watchpoint view, you can also specify a filter in
terms of the internal table, or database table. ("Stops at DELETE dbtab,
but only for dbtab = SFLIGHT)
