  The SAP error message RSDODSO119 indicates that a DataStore Object (DSO) in SAP BW (Business Warehouse) does not have any InfoObjects defined in its key part. This is a critical requirement because a DataStore Object must have at least one key field to uniquely identify records.
  Cause:
  The primary cause of this error is that when creating or modifying a DataStore Object, no InfoObjects were assigned to the key part of the DSO. The key part is essential for the DSO to function correctly, as it determines how data is stored and retrieved.
  Solution:
  To resolve this error, you need to ensure that at least one InfoObject is assigned to the key part of the DataStore Object. Here are the steps to do this:
  
  
  Open the DataStore Object: Go to the Data Warehousing Workbench (transaction code RSA1) and navigate to the DataStore Object that is causing the error.
  
  
  Edit the DSO: Select the DSO and choose the option to edit it.
  
  
  Define Key Fields:
  
  In the DSO definition, locate the section for the key fields.
  Add at least one InfoObject to the key part. This can be done by selecting the InfoObject from the available list and moving it to the key fields section.
  
  
  
  Save Changes: After adding the necessary InfoObject(s) to the key part, save your changes.
  
  
  Activate the DSO: Once the changes are saved, activate the DataStore Object to ensure that the new configuration is applied.
  
  
  Related Information:
