• What is the cause and solution for SAP error message 37144 - One variable (vertically resizeable) loop already exists. Not executed ?

  The SAP error message 37144, "One variable (vertically resizeable) loop already exists. Not executed," typically occurs in the context of SAP BusinessObjects Web Intelligence (WebI) reports. This error indicates that there is an attempt to create a second vertically resizable loop in a report, which is not allowed.
  Cause:
  The error arises when:
  
  You have created a variable loop (a loop that allows for dynamic resizing of the report based on the data) in your report.
  You attempt to create another vertically resizable loop, which is not permitted because only one such loop can exist in a report at a time.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Existing Loops: Check your report for any existing vertically resizable loops. You can do this by reviewing the structure of your report and looking for any variables that are set to be vertically resizable.
  
  
  Remove or Modify Existing Loop: If you find an existing loop that is causing the conflict, you can either:
  
  Remove the existing loop if it is not needed.
  Modify the existing loop to accommodate the new requirements without creating a second loop.
  
  
  
  Use Alternative Approaches: If you need to display data in a way that requires multiple loops, consider using alternative methods such as:
  
  Using a single loop with additional variables or dimensions.
  Restructuring your report layout to avoid the need for multiple loops.
  
  
  
  Check for Report Design Best Practices: Ensure that your report design follows best practices for WebI reports, which can help avoid such issues in the future.
