• What is the cause and solution for SAP error message DAAG_DESIGNTIME336 - No key relationship exists between tables &1 and &2 ?

  The SAP error message DAAG_DESIGNTIME336 indicates that there is no key relationship defined between two tables in a data model or a query. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to create a join or a relationship between two tables that do not have a defined key relationship.
  Cause:
  
  Missing Foreign Key Relationship: The most common cause is that the tables involved do not have a foreign key relationship defined in the data model.
  Incorrect Table Selection: You may be trying to join tables that are not meant to be joined or that do not share a common key.
  Data Model Configuration: The data model may not be properly configured to establish relationships between the tables.
  Table Structure Changes: Changes in the structure of the tables (like renaming or deleting key fields) can lead to this error.
  
  Solution:
  
  
  Define Key Relationships:
  
  Go to the data model or the relevant transaction (like RSA1 for BW) and check the definitions of the tables.
  Ensure that the necessary foreign key relationships are defined between the tables. You can do this by editing the InfoObjects or the data model to include the required keys.
  
  
  
  Check Table Structures:
  
  Verify the structure of both tables to ensure that they have the necessary key fields that can be used to establish a relationship.
  If the key fields are missing, you may need to add them or adjust the table definitions.
  
  
  
  Review Data Model:
  
  If you are working with a composite provider or a calculation view, ensure that the joins are correctly defined and that the key fields are included in the join conditions.
  
  
  
  Use the Right Tables:
  
  Make sure that you are using the correct tables that are intended to be joined. Sometimes, using the wrong table can lead to this error.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on how to define relationships between tables in your specific version of SAP.
  
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like RSA1 (for BW) or HANA Studio for modeling to check and define relationships.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  Data Modeling Best Practices: Familiarize yourself with best practices for data modeling in SAP BW or HANA to avoid such issues in the future.
  
  By following these steps, you should be able to resolve the error and establish the necessary key relationships between the tables.
