JR47151: MIGRATING AN ABAP RFC JOB FROM NON-UNICODE SAP SERVER TO UNICODE DOES NOT CORRECTLY UPDATE THE COLUMN LENGTH VALUES.

APAR status

• Closed as program error.

Error description

• When migrating non unicode SAP ABAP RFC job to unicode SAP
  server, the column length are divided by 2 causing truncation.
  

Local fix

Problem summary

• Migrating an ABAP RFC job from non-Unicode to Unicode SAP Server
  does not correctly update the column lengths, resulting in
  truncated extracted data.
  

Problem conclusion

• For non-Unicode systems the column's "length" is equal to
  "display length" in the ABAP stage GUI. When migrating to
  Unicode, the "display length" should be double the "length". The
   stage uses the "display length" as internal field length; since
   data is stored internally in UTF16 that value is double the
  length.
  Implemented a code fix that will allow the user to migrate using
  the steps described in this technote:
  http://www-01.ibm.com/support/docview.wss?uid=swg21441945
  
  Please note the steps have to be followed specifically. It is
  recommended the migration scenario to use a new connection for
  the Unicode server.
  In case the migration scenario does not use a new connection,
  but it's reusing the old connection name (and just the details,
  eg. host name, are changed), the user has to set the migration
  flag by temporarily selecting a different connection, then
  reselecting the original connection (at step 3). This way a
  "connection change" is simulated and the migration code is
  activated.
  
  Note: this fix is required since the fix for JR41420 (introduced
  in version 6502 and 70) while fixing the issue reported there,
  has also broken the migration path. That also means version 6501
  does not present the issue in JR47151 and does not require a fix
  (the steps in the technote would work fine)
