  The SAP error message PAK161 indicates that there is an issue with the filter package interfaces in the context of the SAP Process Integration (PI) or Process Orchestration (PO) environment. Specifically, this error occurs when the filter package is expected to contain only objects of type 'PCHK' (which stands for "Process Check"), but it contains other types of objects.

  Check Dependencies: Ensure that any dependencies or references to other objects are correctly configured and do not include incompatible types.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to filter packages and the specific version of SAP you are using for any additional guidance or best practices.
