Dear Concern,
I made a Z table in development server, in SE14 when i press check button for this table than it is showing that table is inconsistent, that primary index 0 does not exist.

so i try to create that index from SE14 screen but it shows another error message. that is:
Message no. DI006
It was not possible to create the index in the database.
This could be caused by the fact that an index with the same name exists in the database, but it is unknown to the ABAP/4 Dictionary. Activating the index in the ABAP/4 Dictionary is possible, but it is not possible to create it in the database.
For more information about the cause of the error, analyze the SQL error messages in this log.
so how do i activate that primary index????
