• What is the cause and solution for SAP error message RSDRO126 - Transfer structure for export DataSource has to be regenerated ?

  The SAP error message RSDRO126 indicates that the transfer structure for an export DataSource needs to be regenerated. This typically occurs in the context of SAP BW (Business Warehouse) when there are changes made to the underlying data model or when the DataSource has been modified.
  Cause:
  
  Changes in the DataSource: If there have been changes to the DataSource definition, such as adding or removing fields, the transfer structure may become outdated.
