  The SAP error message 37506, "The type of & is not possible in a dynpro," typically occurs when there is an issue with the data type of a field in a screen (dynpro) in an SAP ABAP program. This error indicates that the data type being used for a field is not compatible with the dynpro screen.
  Causes:
  
  Incompatible Data Type: The field type defined in the ABAP program does not match the expected data type for a screen field. For example, using a complex data type or a reference type that cannot be displayed on a screen.
  Field Length Issues: The length of the field may exceed the maximum allowed length for a screen field.
  Incorrect Field Definition: The field may not be defined correctly in the screen layout or in the ABAP program.
  Use of Non-Primitive Types: Using non-primitive types (like structures or internal tables) directly in screen fields can lead to this error.
  
  Solutions:
  
  Check Field Definitions: Review the field definitions in the ABAP program and ensure that they are compatible with the screen fields. Use primitive data types (like CHAR, NUMC, DATS, etc.) for screen fields.
  Adjust Field Lengths: Ensure that the lengths of the fields defined in the ABAP program do not exceed the maximum lengths allowed for screen fields.
  Modify Screen Layout: If necessary, modify the screen layout to accommodate the correct data types and lengths.
  Use Simple Data Types: If you are using complex data types, consider breaking them down into simpler components that can be displayed on the screen.
  Check Screen Attributes: Ensure that the attributes of the screen fields are set correctly in the screen painter.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE80 (Object Navigator) or SE41 (Menu Painter) to check and modify the screen and field definitions.
  ABAP Data Dictionary: Use transaction SE11 to check the data dictionary definitions for the fields involved.
  Debugging: If the error persists, consider using the debugger to trace the program execution and identify where the incompatible data type is being used.
