SAP Message UCM0032 - Data from tables that use structure &1 must be converted

Diagnosis
The generated structure &V1& is used in database tables that alreadycontain data. The current generation run discovered that the structureof table &V1& (logical name &V4&) has been changed. To prevent datacorruption, the system has created a new structure with the name &V2&.This structure corresponds to version number &V3& for logical objectV4.
The system is now in an inconsistent state!

Procedure
To restore consistency, the data in table that uses structure &V1& mustbe converted to new tables that use the new structure &V2&. If thesedata-filled tables are not generated for a consolidation area, you mustcreate the new tables yourself in the Data Dictionary.
