How To Fix CNV_IUUC_REPLICATION062 - No assignment of a key field structure for table &1 RELID &2

CNV_IUUC_REPLICATION062 - Overview

• Message type: E = Error

• Message class: CNV_IUUC_REPLICATION - IUUC replication messages (HANA)

• Message number: 062

• Message text: No assignment of a key field structure for table &1 RELID &2

What causes this issue?

It is tried to define a data transfer (initial load and/or replication)
for table &SYST-MSGV1&.As this is an INDX-like table, it cannot be
directly replicated, but it is necessary to define an assignment of
logical tables to this table. These logical tables have a key structure
which is specific for the possible RELID values of table &SYST-MSGV1& .
The assignment of the appropriate key structure is missing for RELID
&SYST-MSGV2&.

System Response

The requested activity could not be performed for this table.

How to fix this error?

Maintain, in table IUUC_INDX_KEYDEF, the assignment of key structures to
all the possible RELID values of table &SYST-MSGV1&

  Replication 
  Configuration Issues: There may be issues with the replication configuration settings that prevent the correct identification of key fields.
  Inconsistent Data Model: The data model in the source system may not match the expected model in the target system.
