Symptom
You are executing a remote client copy. Unfortunately, below error is coming out,
Critical differences: Missing tables: x
Message no. TA254
Diagnosis
The table definitions between the systems are different. These
differences can be converted in a client copy.Such differences can be caused by the following:
o Different maintenance and release levels
o Developments and modifications which were not transported
o Different customizing in which table structures were generated.
Uncritical can mean that the target system can contain more fields than
the source system for some tables. Some tables could also be missing in
the source system.The fields and tables are not filled in these cases.
Procedure
Transport all the developments to the target system using the Workbench
Organizer or TMS in the target system and execute the client copy
between systems with the same development level if this is possible.
You noticed that all the tables are existed on the source system but not in the target system (from transaction code SE16 / SE16N)
Solution
Refer to SAP Note 1692763.
In order to solve this:
• Please check if the Support Package level is the same and the customer objects have also the same version in the two systems. This is mentioned in SAP Note 557132 for Remote Client Copies and SAP Note 70547 for Transport Client Copy;
• If the table(s) is(are) missing on the target client/system, customer must transport the R3TR TABL [table_name] object from another system with the same SP level. It is not needed to transport the R3TR TABU object because it transports the contents of the table, and as we are doing a client copy, the client copy itself will transfer the needed data from one client to the other. The first step of a client copy is to delete the data from the target client, therefore, transporting the R3TR TABL object is enough.
• If the table(s) is/are not needed on the target client/system, they can be excluded from the Client Copy using report RSCCEXPT (SAP Note 70290 explains how to use the report).
