• What is the cause and solution for SAP error message FKKBIX021 - Maximum number of tables reached ?

  The SAP error message FKKBIX021, which states "Maximum number of tables reached," typically occurs in the context of the SAP system's ability to handle a certain number of database tables in a single operation or transaction. This error is often encountered when working with the SAP Financial Accounting (FI) module, particularly during processes that involve a large number of line items or when generating reports that require data from multiple tables.
  
  Cause:
  
  Limit on Table Joins: SAP has a limit on the number of tables that can be joined in a single query or operation. When this limit is exceeded, the FKKBIX021 error is triggered.
  Complex Queries: If a query or report is designed to pull data from too many tables, it can exceed the system's capacity to process them in one go.
  Large Data Volume: Operations involving large volumes of data can also lead to this error, especially if they require extensive joins
