The tables and links defined do not allow a join to be added here
Note that ABAP SQL does not support the following situations:
The right-hand table of a left-outer join is also the right-hand table
of another joins, that means:
a right table of a left-outer joins can only be linked with a left-hand
table.
A right-hand table of a left-outer joins is the left-hand table of
another left-outer join.

• What is the cause and solution for SAP error message AQQIS_CNTRL036 - No left outer join can be defined here ?

  The SAP error message AQQIS_CNTRL036, which states "No left outer join can be defined here," typically occurs in the context of SAP Query or SAP ABAP when you are trying to create a query that involves a left outer join between tables, but the system does not allow it due to certain constraints.
  Cause:
  
  
  Table Relationships: The tables you are trying to join may not have a valid relationship that allows for a left outer join. In SAP, certain tables are designed to be joined in specific ways, and attempting to create a left outer join where it is not supported will trigger this error.
  
  
  Query Design: The design of the query may not support left outer joins due to the way the data is structured or the specific fields being used in the join condition.
  
  
  Data Dictionary Constraints: The data dictionary (DDIC) may have constraints that prevent the use of left outer joins for the specific tables involved.
  
  
  Solution:
  
  
  Check Table Relationships: Review the relationships between the tables you are trying to join. Ensure that they are designed to support a left outer join. You can do this by checking the data dictionary (transaction SE11) for the tables involved.
  
  
  Use Inner Joins: If a left outer join is not necessary for your query, consider using an inner join instead. This may resolve the issue if the data you need can be retrieved with an inner join.
  
  
  Modify Query Design: If you need to keep the left outer join, consider redesigning your query. You may need to break it down into smaller parts or use subqueries to achieve the desired result without directly using a left outer join.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific tables and their relationships. This can provide insights into how to structure your query correctly.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with an experienced SAP developer or functional consultant who can provide assistance based on your specific scenario.
  
  
  Related Information:
  
  SAP Query: If you are using SAP Query (transaction SQ01), familiarize yourself with the limitations and capabilities of the query tool regarding joins.
  ABAP Development: If you are working in ABAP, understanding how to properly use joins in SQL statements is crucial. Review the ABAP documentation for best practices on joins.
  Data Dictionary (SE11): Use transaction SE11 to explore the structure of the tables involved and their relationships.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution that allows you to retrieve the data you need without encountering the AQQIS_CNTRL036 error.
