类定义内的ABAP“ SET EXTENDED CHECK”语句

Question

In a customer object, I see the following ABAP code:

CLASS lcl_detail DEFINITION FINAL.
  SET EXTENDED CHECK OFF.      
  PUBLIC SECTION.
  [...]
ENDCLASS.

I've performed a syntax check on an SAP 7.40 system and it is fine. But if I check the 7.40 ABAP Keyword documentation of CLASS DEFINITION , it does not say that SET EXTENDED CHECK is allowed in this place. Also, I though there shouldn't be anything between the CLASS DEFINITION part and the first SECTION part.

Answer 1

Since the SET EXTENDED CHECK {ON|OFF} statement is used to activate/deactivate the complete check of the ABAP source code for all errors that can be detected statically, it can be put in any section of a program.

It is not used in program's execution. It's used when you run the extended program check (SLIN or ABAP Test Cockpit).
