• What is the cause and solution for SAP error message BK020 - Function & is not possible (maximum number of items = &) ?

  The SAP error message BK020 indicates that a function cannot be executed because the maximum number of items has been reached. This typically occurs in the context of financial transactions, such as when processing documents in the SAP system, where there is a limit on the number of line items that can be processed in a single transaction.
  Cause:
  The error is triggered when the number of line items in a document exceeds the predefined limit set in the SAP system. This limit is often configured in the system settings and can vary based on the specific transaction or document type being processed.
  Solution:
  To resolve the BK020 error, you can consider the following approaches:
  
  
  Reduce the Number of Line Items:
  
  If possible, split the transaction into multiple smaller transactions, each containing fewer line items than the maximum allowed.
  
  
  
  Check Configuration Settings:
  
  Review the configuration settings in the SAP system to determine the maximum number of line items allowed for the specific transaction. This can usually be found in the configuration settings for Financial Accounting (FI) or the specific module you are working with.
  
  
  
  Increase the Limit:
  
  If your business process requires a higher number of line items, you may need to work with your SAP Basis or configuration team to increase the maximum limit. This involves changing the relevant configuration settings in the system.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific transaction or module to understand any limitations and recommended practices.
