Question:
Hi Friends.
I need answer for my questions.
Please help regarding this.
1)If i delete structure in database.how i can activate again?
Answer:
Simply put you can't
Activate and deletion are two different things.
When you create a structure, you must activate it in order for SAP to be able to use that structure in ABAP programs and other structures or tables.
When you make changes to that structure, those changes can only be seen in the structure editor (SE11) until they are activated. Until then ABAP programs (structures and tables) cannot see the changes.
This enables you to make changes to a structure without fear of screwing up dependant objects with structures that are inconsistant. You can still screw them up, but at least it will not be with a structure that contains for example non existant data elelements.
When you delete a structure you remove it entirely, both active and inactive versions. If you have transported the structure to another system I would think that there are versions in the version history table though.
SO, having deleted a structure, the onbly way to activate it is to re-enter it and then activate it, although if it's a big structure I would first try creating it with just one field and looking in the version history to see if there are any previous versions that you can retrieve.
