• What is the cause and solution for SAP error message STGR021 - Maximum amount of tabstrips exceeded ?

  The SAP error message STGR021, which states "Maximum amount of tabstrips exceeded," typically occurs when the number of tab strips (or tabs) in a particular SAP GUI screen exceeds the allowed limit. This can happen in various scenarios, such as when a user tries to open too many sessions or when a specific transaction or program is designed to create multiple tab strips.
  Cause:
  
  Exceeding Tab Limit: Each SAP GUI session has a limit on the number of tab strips that can be opened. If you try to open more than this limit, you will encounter the STGR021 error.
  Session Management: Users may have multiple sessions open, each with its own set of tab strips, leading to the overall limit being exceeded.
  Custom Development: Custom programs or transactions that create multiple tab strips may inadvertently exceed the limit.
  
  Solution:
  
  Close Unused Tab Strips: Review the open tab strips in your SAP GUI and close any that are not needed. This can help free up space for new tab strips.
  Limit Open Sessions: Try to limit the number of SAP sessions you have open at one time. Each session can contribute to the total number of tab strips.
  Check Custom Programs: If the error occurs in a custom program, review the code to ensure it is not creating unnecessary tab strips. Consider optimizing the design to reduce the number of tabs.
  Increase Tab Limit (if applicable): In some cases, it may be possible to increase the limit of tab strips through configuration settings, but this typically requires administrative access and should be done with caution.
  Log Off and Log Back In: Sometimes, simply logging off from the SAP system and logging back in can reset the session and clear any issues related to tab strips.
