Table Maintenance Generator v/s Maintenance View

[SuhaSaha]

Hello SDNers,

I am into a new project & in this system the developers have created Maintainence View for all Z-tables. None of them have a Table Maint. Generator(TMG) defined. The tables are maintained through custom transactions associated with the views.

I am just thinking what advantage do Maint. Views have over TMG?

Any inputs will be appreciated.

I think views, view clusters, authorization check S_TABU_DIS, TMG incl. transport request handling and maintenance events cover most aspects of customizing or similar tables, I don't see a need for completely custom transactions. Maybe they did not know about TMG or its full features? Did you ask them?

It depends what the Z-tables are used for, if it is a complex application (let's say your own VA01 or so) then it's a different story.

Hello Thomas,

These tables were developed way back in 2002-03. So i have no idea why they have done this. Yes its a very complex interface for which these custom tables are used. May be you can elaborate on it.

Can you be a bit more clear in your response? I did not understand the point you made about "authorization check S_TABU_DIS".

Also another astonishing thing is that the Tables & Maint. generator are assigned to diff. packages. Does this ring a bell?

Suhas, in the end I can't give a good recommendation in this matter without knowing your SAP installation in detail. I can only say that personally I would always use generated table maintenance dialogs whenever possible.

Regarding your question, S_TABU_DIS is the authorization object for checking the authorization group that you can assign to a table maintenance dialog.

Hello,

Ok let me put it this way: Do Maint. Views have any advantage over TMG? I too prefer creating a TMG (infact i have never created any Maint. Views as such )

Your question is a little confusing. A "maintenance view" is a DDIC object like a table. It's a view on one or several tables to be used in generated maintenance dialogs, just as you can generated them for tables. I frequently use maintenance views and sometimes also view clusters.

So you cannot really ask "should I use maint. views or TMGs?".

Suhas - Many times we create Maintenance view to use this in our program. I am not sure whether, there is any req. like that or not. You may check with a where used list. Otherwise, I couldn't find a reason.

Sorry - Ignore my previous post, I was confused with Database View.
