How To Fix RSPC104 - Collector processes are not useful as end point

SAP Error Message - Details

• Message type: E = Error

• Message class: RSPC - Process Chains

• Message number: 104

• Message text: Collector processes are not useful as end point

What causes this issue?

Your chains ends with collector processes (AND, OR, EXOR).

System Response

This design is not necessary.
On the one hand, a process chain may have any number of end points. The
end of the run is determined by a graphic-theoretic algorithm.
On the other hand, this setting unnecessarily burdens your system since
additional batch jobs run for each collector process. You are simply
complicating the chain by doing this, as you will see clearly in the
detailed view.
What's more, a process error in the chain would not be determined at
runtime if your chain ends with AND processes, which are only executed
if the run is successful. Because with this design, the prerequisite for
ending an AND process (= determine the status of the chain) is that all
previous processes must run successfully, which would not be the case if
errors occurred.

How to fix this error?

Remove the additional AND, OR and EXOR processes if they do not have
successors, or add a successor to the chain.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RSPC104 - Collector processes are not useful as end point ?

  The SAP error message RSPC104, which states "Collector processes are not useful as end point," typically occurs in the context of SAP Process Chain (PC) execution. This error indicates that the process chain is trying to use a collector process as an endpoint, which is not allowed because collector processes are designed to aggregate data from other processes rather than serve as a final endpoint.
  Cause:
  
  Incorrect Process Chain Design: The process chain may have been designed incorrectly, where a collector process is mistakenly set as the last step in the chain.
  Misconfiguration: There may be a misconfiguration in the process chain that leads to the collector being treated as an endpoint.
  Process Type Misunderstanding: Users may not fully understand the role of collector processes, leading to improper placement within the process chain.
  
  Solution:
  
  
  Review Process Chain Design:
  
  Open the process chain in the SAP Process Chain maintenance transaction (e.g., RSPC).
  Check the sequence of processes and ensure that the last step is not a collector process.
  Replace the collector process with an appropriate endpoint process, such as a data transfer or a data load process.
  
  
  
  Modify the Process Chain:
  
  If a collector is necessary for data aggregation, ensure it is placed correctly within the chain, but not as the final step.
  Add a valid endpoint process after the collector if needed.
  
  
  
  Testing:
  
  After making changes, test the process chain to ensure it runs successfully without errors.
  
  
  
  Related Information:
  
  
  Process Types: Understand the different types of processes in SAP Process Chains, including:
  
  Data Transfer Processes (DTP): Used for data extraction and loading.
  InfoPackage: Used for data extraction from source systems.
  Collector Processes: Used to aggregate data from multiple processes but cannot be the endpoint.
  
  
  
  Documentation: Refer to SAP documentation or help resources for detailed information on designing process chains and the roles of different process types.
  
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to this error message.
  
  
  By following these steps, you should be able to resolve the RSPC104 error and ensure that your process chain executes successfully.
