• What is the cause and solution for SAP error message K0155 - Full display mode activated ?

  The SAP error message K0155, which states "Full display mode activated," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with reports or transactions that involve cost centers, internal orders, or other controlling objects. This message indicates that the system has switched to a full display mode, which may limit certain functionalities or performance.
  Cause:
  The activation of full display mode can be triggered by several factors, including:
  
  Data Volume: When the system detects a large volume of data being processed, it may switch to full display mode to ensure that all relevant information is displayed, albeit at the cost of performance.
  User Settings: User-specific settings or preferences may dictate the display mode. If a user has set their preferences to always show full details, this message may appear.
  System Configuration: Certain configurations in the SAP system may lead to the activation of full display mode, especially if the system is set to prioritize data completeness over performance.
  
  Solution:
  To address the K0155 error message, consider the following solutions:
  
  Adjust Display Settings: Check your user settings in SAP. You may be able to change the display mode to a more performance-oriented setting if full display is not necessary for your tasks.
  Limit Data Selection: If you are running a report or transaction that processes a large amount of data, try to limit the selection criteria to reduce the volume of data being processed. This can help avoid triggering full display mode.
  Performance Optimization: Work with your SAP Basis team to optimize system performance. This may involve tuning database queries, adjusting memory settings, or other performance-related configurations.
  Consult Documentation: Review SAP documentation or notes related to the specific transaction or report you are using. There may be specific recommendations or known issues that can help resolve the situation.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any updates or patches related to the K0155 message. SAP frequently releases notes that address specific issues or provide guidance on error messages.
  User Forums: Engage with SAP community forums or user groups. Other users may have encountered the same issue and can provide insights or solutions based on their experiences.
  Training and Documentation: Ensure that users are trained on how to effectively use the reporting tools within SAP, including understanding the implications of different display modes.
  
  If the issue persists after trying the above solutions, it may be beneficial to escalate the matter to your SAP support team for further investigation.
