How To Fix RS_HCPR_MODEL029 - Temporal join: Cannot map navigational attribute &1

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 029

• Message text: Temporal join: Cannot map navigational attribute &1

What causes this issue?

Within a temporal join<(>,<)> only time-independent navigational
attributes coming from a base InfoCube can be assigned. No other
navigational attributes are supported.
Navigational attributes were mapped where the source PartProvider is not
a base InfoCube, or the source PartProvider is a base InfoCube but its
navigational attribute is time-dependent.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The CompositeProvider can be activated by either removing the
time-dependency, or all assignments of navigational attributes coming
from a PartProvider that is not a base InfoCube.

• What is the cause and solution for SAP error message RS_HCPR_MODEL029 - Temporal join: Cannot map navigational attribute &1 ?

  The SAP error message RS_HCPR_MODEL029 indicates that there is an issue with a temporal join in your data model, specifically that a navigational attribute cannot be mapped. This typically occurs in the context of SAP HANA or SAP BW when working with data models that involve time-based data.
  Cause:
  The error is usually caused by one of the following issues:
  
  
  Missing Mapping: The navigational attribute specified in the error message (&1) is not properly mapped in the data model. This could be due to a misconfiguration in the data model or an oversight during the design phase.
  
  
  Incompatible Data Types: The data types of the navigational attribute and the corresponding field in the target table may not match, leading to mapping issues.
  
  
  Incorrect Join Conditions: The join conditions defined in the model may not correctly relate the tables involved, causing the system to be unable to find a valid mapping for the navigational attribute.
  
  
  Temporal Data Issues: If the data model involves temporal data, there may be issues with the time dimension or the way the temporal join is defined.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Mapping: Review the data model to ensure that the navigational attribute is correctly mapped. Make sure that the attribute exists in the source and target tables and that it is correctly defined in the model.
  
  
  Verify Data Types: Ensure that the data types of the navigational attribute in both the source and target tables are compatible. If they are not, you may need to adjust the data types or perform necessary transformations.
  
  
  Review Join Conditions: Examine the join conditions in your data model. Ensure that they are correctly defined and that they logically connect the relevant tables.
  
  
  Check Temporal Settings: If you are working with temporal data, verify that the temporal settings are correctly configured. Ensure that the time dimension is properly defined and that the temporal join is set up correctly.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for additional guidance on temporal joins and navigational attributes. There may be specific considerations or best practices that apply to your scenario.
  
  
  Test Changes: After making adjustments, test the data model to ensure that the error is resolved and that the data is being processed as expected.
  
  
  Related Information:
