• What is the cause and solution for SAP error message 37818 - Creates a new table control on the dynpro ?

  The SAP error message 37818, which states "Creates a new table control on the dynpro," typically occurs during the development of SAP applications, particularly when working with screen programming (dynpro) in ABAP. This error indicates that there is an attempt to create a new table control on a screen (dynpro) that already has a table control defined.
  Cause:
  
  
  Duplicate Table Control Definition: The most common cause of this error is that there is an attempt to define a new table control in the screen layout (dynpro) when one already exists. This can happen if the screen is being modified and a new table control is added without removing or properly managing the existing one.
  
  
  Incorrect Screen Attributes: Sometimes, the screen attributes may not be set correctly, leading to conflicts in the definition of table controls.
  
  
  Screen Number Conflicts: If multiple developers are working on the same screen or if there are conflicting screen numbers, this error can arise.
  
  
  Solution:
  
  
  Check Existing Table Controls: Review the screen layout in the Screen Painter (SE80 or SE41) to see if there is already a table control defined. If so, you may need to modify the existing control instead of creating a new one.
  
  
  Remove Duplicate Definitions: If you find that there are duplicate definitions, remove the unnecessary table control or adjust the existing one to accommodate your requirements.
  
  
  Review Screen Attributes: Ensure that the screen attributes are correctly set and that there are no conflicts in the definitions.
  
  
  Use the Correct Screen Number: If you are working in a development environment, ensure that you are using the correct screen number and that there are no conflicts with other developers.
  
  
  Check for Code Issues: Review the ABAP code associated with the screen to ensure that there are no programmatic attempts to create a new table control that conflict with the existing one.
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE80 (Object Navigator) or SE41 (Menu Painter) to access and modify screen layouts.
  Documentation: Refer to SAP documentation on screen programming and table controls for best practices and guidelines.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to this error message.
