SAP Error Message - Details

• Message type: E = Error

• Message class: RS_HCPR_MODEL - Messages related to the HANA Composite Provider Backend

• Message number: 039

• Message text: Temporal join: No support Nav. attr. - source &1 (&2), target: &3

If the InfoSet runtime is used for CompositeProviders<(>,<)> navigation
attributes cannot be used. To model this, master data must be joined.
There is one exception: Time-independent navigation attributes of an
InfoCube cointained in a CompositeProvider can be handled as normal
attributes. As a result, the master data does not have to be joined to
the InfoCube to be able to access its navigation attributes.

  The SAP error message RS_HCPR_MODEL039 indicates an issue with a temporal join in a data model, specifically related to navigation attributes. This error typically arises when you are trying to perform a temporal join between two data sources, and one of the sources has navigation attributes that are not supported in the context of the join.

  Navigation Attributes: The source data source (&1) has navigation attributes that are not compatible with the target data source (&3) in the context of the temporal join. This can happen if the navigation attributes are not defined correctly or if they are not supported for the type of join you are trying to perform.
  Data Model Configuration: There may be issues in the configuration of the data model, such as incorrect settings for the temporal join or the attributes involved.

  Check Navigation Attributes: Review the navigation attributes defined in the source data source (&1). Ensure that they are correctly configured and supported for the temporal join you are attempting.
  Modify Data Model: If the navigation attributes are not necessary for the join, consider removing them or modifying the data model to avoid using unsupported attributes.
  Review Join Conditions: Ensure that the join conditions between the source and target data sources are correctly defined and that they do not involve unsupported navigation attributes.
  Consult Documentation: Refer to SAP documentation for temporal joins and navigation attributes to understand the limitations and requirements for your specific version of SAP.
  Testing: After making changes, test the data model to ensure that the error is resolved and that the join works as expected.
