Read the following information before you perform TDM operations on identity columns:
You cannot move data from a source DBO schema to a target non-DBO schema on a Sybase database if the data contains an identity column and indexes.
If you enable the auto identity option in the database and there are no primary keys or unique keys in a table, Sybase adds the SYB_IDENTITY_COL column. You must mark the column as restricted. A workflow fails if you do not mark the SYB_IDENTITY_COL column as restricted.
To disable an identity column on a Microsoft SQL Server database, the database user must have execute permission on sp_help.
