Replacements for Obsolete Language Constructs in ABAP Objects
The ABAP language has been cleaned up in ABAP Objects. As part of this language clean-up, stricter syntax checks are performed for constructs that were previously allowed, or obsolete statements are no longer allowed at all. The stricter syntax checks usually result in syntax which we also recommend for use outside of ABAP Objects but where the old versions cannot be forbidden for compatibility reasons.
The syntax revisions are listed in detail in the documentation of the languaghe elements and also in the list of
obsolete language elements .
The syntax revisions apply to all
statements in ABAP Objects .
