• What is the cause and solution for SAP error message RSDS086 - Multi-segment extraction not possible without join field "object ID" ?

  The SAP error message RSDS086 indicates that a multi-segment extraction is not possible because the required join field "object ID" is missing. This typically occurs in the context of data extraction from SAP BW (Business Warehouse) or SAP HANA, where data is being pulled from multiple segments or tables that need to be joined based on a common field.
  Cause:
  The error arises when:
  
  Missing Join Field: The extraction process requires a join field (in this case, "object ID") to link different segments of data. If this field is not present in the data model or the extraction setup, the system cannot perform the necessary joins.
  Incorrect Data Model: The data model may not be correctly defined to include the necessary fields for multi-segment extraction.
  Configuration Issues: There may be issues in the configuration of the InfoProvider or the DataSource that prevent the join field from being recognized.
  
  Solution:
  To resolve the RSDS086 error, you can take the following steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and verify that the "object ID" field is included in the DataSource definition.
  Ensure that the DataSource is correctly configured to extract data from the relevant tables.
  
  
  
  Review InfoProvider:
  
  Check the InfoProvider (e.g., InfoCube, DataStore Object) to ensure that it includes the "object ID" field.
  If the field is missing, you may need to modify the InfoProvider to include it.
  
  
  
  Modify the Data Model:
  
  If the "object ID" is not part of the data model, consider adding it to the relevant tables or segments that are being extracted.
  Ensure that the relationships between the tables are correctly defined to facilitate the join.
  
  
  
  Check for Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as there may be fixes related to data extraction issues.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific DataSource or InfoProvider you are working with for any additional configuration steps or requirements.
  
  
  
  Testing:
  
  After making the necessary changes, test the extraction process again to ensure that the error is resolved.
