tr and toc in sap abap

[vieet]

I have created a program inside TR name TR1 . The program contains write statement "This is sap abap". When I execute it , it is showing the same.
I have created TOC name it TOC1 for it and moved to QAS. I could find the program and when I execute it , it is showing as "This is sap abap".

Now I have made changes in the program and added the second line "Hello World". I executed it and it is showing as "This is sap abap. Hello world".
I have created another toc name it TOC2 for it and moved to QAS. When I execute the program it is showing me "This is sap abap. Hello world".

NOw I have deleted TOC2 from the QAS from stms_import, I was expecting that when I run the program now, it should show me "This is sap abap".
The changes of the second TOC are not roll back .
I want to undo the changes of TOC2  and show me only the TOC1 .... How can I achieve this?

You did not understand what a TR is (whatever it's TOC or not). It's a container of "things". The "things" are changed only after an import of a TR.

If you want the previous statement, then you have to Reimport TOC1 but not removing TOC2 from STMS
