0x00720608 (7472648) The data cannot be captured for the column, column-name because it references a segment, segment-name that does not exist in the DBD DBD-name.

Explanation
An attempt is being made to alter an IMS table for data
capture. However the segment-name that is associated with
the column-name cannot be found in the DBD that is loaded
from the DBDLIB that is included in the data server JCL.  

User response
Verify that the correct DBDLIB is specified in the data
server JCL. Restart the data server and run the ALTER statement again. If
the DBDLIB is correct, drop the table definitions and recreate it to specify
a DBD that is loaded from the DBDLIB.
