How To Fix SY474 - READ BINARY SEARCH check switched off

SY474 - Overview

• Message type: E = Error

• Message class: SY - ABAP/4 system messages

• Message number: 474

• Message text: READ BINARY SEARCH check switched off

What causes this issue?

You can only use the READ ... BINARY SEARCH statement if the relevant
internal table is sorted by the key used. Otherwise any table row will
be found.

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

To find such program errors there is a test that can be switched on in
the ABAP Debugger. This test checks before every READ ... BINARY SEARCH
statement whether the table is sorted. If this is not the case, a
runtime error occurs.
With large tables this test takes a long time and hence can have a
significant negative effect on the program's runtime.
