Logical system name conversion can be performed by using

  • Transaction BDLS or program RBDLSMAP
  • Program RBDLS2LS

Programs looks for all references to fields of data type "LOGSYS" and "EDI_PARNUM" and changes these values to the new logical system name (from the old one).

System will always convert the whole column or nothing; Partly conversion is not possible. Root cause why system did not convert the column: duplicate entries

BDLS should not be executed on a productive system (SAP Note 544509)

Recommendation for executing BDLS:

  • Test run: tables will be determined and program will be generated
  • Always check the log after BDLS execution and make sure that table RSBASIDOC has been converted. Duplicate entries are only possible in case the original system is connected to the overwritten system as a sending or receiving system.  Have a look at SAP KBA 2005253 and do not execute any further steps in order to avoid a new BW system copy.

If you use  RBDLS2LS the following notes should be considered as some BW specific tables will not be converted:
