  The SAP error message SPOC136, which states "Endless recursion through base device type for &1," typically occurs in the context of device types in SAPscript or Smart Forms. This error indicates that there is a circular reference in the device type hierarchy, meaning that a device type is referencing itself or is part of a loop of references that leads back to itself.
  Cause:
  
  Circular Reference: The most common cause of this error is a circular reference in the device type configuration. For example, if Device Type A is based on Device Type B, and Device Type B is based on Device Type A, it creates an endless loop.

  Check Device Type Configuration:
  
  Go to transaction SPAD (Spool Administration).
  Navigate to the device types and check the configuration of the device type mentioned in the error message.
  Ensure that the base device type is correctly defined and does not create a circular reference.
