Version Management

I am able to retrieve old copy of my Z Program through version management... like to know whether SAP stores all copies of the "entire" program in the database or only all copies of "changes" done in the program.

Advance thanks.

    Hello Balaji,

    It is my understanding that the versions are all stored as complete copies, rather than as a set of changes. As you might be aware, the ABAP source code is stored in the database in a cluster table (in a compressed form).

    So, it would be disadvantageoues to store it in the form of just the changes made from version to version, since that would require considerable amount of processing when the user requests a particular version. For example, let us say that there is a program which has about 50 versions. If only the changes were to be stored, then when the user requests a comparison of version 1 with version 50, imagine the amount of processing that would have to be done. Also, it is difficult to maintain the versions as changes.

    Also, think about the option <i>Remote Comparison</i> in version management. I guess this resolves the doubt that you have had. If yes, then please do reward the points :-). Else, please do get back.
