• What is the cause and solution for SAP error message BRAIN123 - Query &1/&2 may not have read mode 'A' ?

  The SAP error message BRAIN123 indicates that a query (specifically a BEx query) is attempting to use a read mode that is not allowed. The read mode 'A' refers to "All" mode, which is typically not permitted for certain types of queries, especially those that are designed to work with specific data selections or aggregations.
  
  Cause:
  
  Query Configuration: The query may be configured to use a read mode that is not compatible with its settings. For example, if the query is designed to return specific data based on certain filters or characteristics, it may not support the 'A' mode.
  Data Source Restrictions: The underlying data source (like an InfoProvider) may have restrictions that prevent the use of read mode 'A'.
  Query Properties: The properties of the query might be set in such a way that they do not allow for the 'A' read mode.
  
  
  Solution:
  
  Check Query Properties: Open the query in the BEx Query Designer
