For a package coming from a different system, I have mass-changed its Original System to match the current system. SE03 shows, that all objects were affected by the change, SE80 opens the code without modification assistant.
Eclipse ADT also opens the files without warning, but there are two classes that open in Eclipse write-protected (in the screenshot only line 59 is editable). The same classes open in SE80 without any limitations.
What can be wrong with those two classes, how can I fix that? There are also FMs in the same subpackage, they open without write-protection.
