This error is often encountered in the context of SAP Process Orchestration (PO) or SAP Process Integration (PI) scenarios.
  Cause:
  
  Missing Implementation: The class specified in the error message (&2) does not implement the required interface (/SAPPO/IF_PPO_COMMAND). This can happen if the class was not properly defined or if it was modified incorrectly.
