How To Fix CPOC137 - Only the completing signature may be executed asynchronously

SAP Error Message - Details

• Message type: E = Error

• Message class: CPOC - PP-PI-PMA: Process Operator Cockpit Messages

• Message number: 137

• Message text: Only the completing signature may be executed asynchronously

What causes this issue?

You have set the <DS:DE.CO_SIGNASYN>Asyn. signature process</>
indicator in the process instruction.
This indicator is not taken into account in the PI sheet unless the
following requirements are met:
The <DS:DE.SIG_SH>digital signature</> indicator has been set in
Customizing for the control recipe destination.
A signature strategy has been assigned in Customizing for the control
recipe destination or in the process instruction.
The process instruction is at the very end of the PI sheet, which means
it is used to sign off the entire PI sheet.

How to fix this error?

Assign <LS>synchronous</> as the value of characteristic
PPPI_SIGNATURE_MODE.
Delete characteristic PPPI_SIGNATURE_MODE from the process instruction.

• What is the cause and solution for SAP error message CPOC137 - Only the completing signature may be executed asynchronously ?

  The SAP error message CPOC137, which states "Only the completing signature may be executed asynchronously," typically occurs in the context of SAP Process Orchestration (PO) or SAP Cloud Platform Integration (CPI) when dealing with asynchronous processing of signatures in workflows or processes.
  Cause:
  This error arises when there is an attempt to execute a signature (or a step in a process) asynchronously that is not allowed to be executed in that manner. In SAP workflows, certain steps or signatures are designated to be executed synchronously, meaning they must complete before the process can continue. The error indicates that the system is trying to execute a step that is not permitted to run asynchronously.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review Workflow Design: Check the design of your workflow or process. Ensure that the signatures or steps that are being executed asynchronously are indeed allowed to be executed in that manner. 
  
  
  Adjust Signature Execution: If a signature is meant to be synchronous, ensure that it is configured correctly in the workflow. You may need to change the execution mode of the signature to synchronous if it is currently set to asynchronous.
  
  
  Check Process Configuration: Look into the configuration settings of the process or workflow. Ensure that the settings align with the intended execution flow.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version of the software you are using. There may be specific guidelines or limitations regarding asynchronous execution of signatures.
  
  
  Debugging: If the issue persists, consider enabling debugging or logging to get more detailed information about where the error is occurring. This can help identify the specific step or signature causing the issue.
  
  
  SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance. They can provide more detailed insights based on your specific configuration and usage.
  
  
  Related Information:
  
  SAP Process Orchestration (PO): This is a suite of tools for integrating processes across different systems. Understanding how PO handles workflows and signatures can help in troubleshooting.
  SAP Cloud Platform Integration (CPI): If you are using CPI, familiarize yourself with its capabilities and limitations regarding asynchronous processing.
  Workflow Management: Understanding the principles of workflow management in SAP can provide insights into how to design processes that avoid such errors.
  
  By following these steps, you should be able to identify the cause of the CPOC137 error and implement a solution to resolve it.
