Explanation:
This message occurs during a TABLELOAD run when a column of the target table is defined in such a way that its values must be stored with a fixed length, but the corresponding columns in the source table only contain values of variable length.
User Action:
If you decide to continue the execution, the definition of the source table is taken over and neither the values taken over nor the values inserted later are stored as fixed-length values. Otherwise, the TABLELOAD run is continued with the next table.
