Internal system error. The actual key length must be less than the definition length, which must be less than 128 bytes. Null key (i.e., key length=0) is not allowed for a primary key, table parameter, and secondary key of syntax B or P.
If this message is received as a result of attempting a SIXBUILD, the target table's definition may have been modified to make the partial Secondary Index unusable. To avoid future table access problems, you must issue a SIXDELETE against the same field that caused the error, this will reset the definition.
For other requests (non-SIXBUILD), no action is necessary. You cannot insert a NULL into a key or parm field of syntax B or P.
