How To Fix WFCS224 - Parallel processing: Timeout for &1 (number: &2)

SAP Error Message - Details

• Message type: E = Error

• Message class: WFCS - Message Class for Store Forecasting (Dev. Package WFCS)

• Message number: 224

• Message text: Parallel processing: Timeout for &1 (number: &2)

What causes this issue?

The system uses this program in parallel processing mode.
This message gives information on how often the maximum waiting time
was exceeded in each of the queues. The program waits in three program
stages in total:
T1 (<DS:DE.WFCS_TIME_WAIT_TASK_FULL>Waiting time 1</>)
The system waits because the maximum number of processes are occupied
and it cannot start any new processes. The maximum waiting time was
reached. You can enter the waiting time and the maximum waiting time
for each run in the selection screen.
T2 (<DS:DE.WFCS_TIME_WAIT_NO_RESOURCES>Waiting time 2</>)
The system waits because it was unable to find any free resources when
when attempting to start a new process. The maximum waiting time was
reached. You can enter the waiting time and the maximum waiting time
for each run in the selection screen.
TR (<DS:DE.WFCS_TIME_TASK_RETURN>Waiting time for task return</>)
After processing all the stores, the system waits until all the
processes started have reported back to the main program. The maximum
waiting time was reached. You can enter the waiting time and the
maximum waiting time for each run in the selection screen.

System Response

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

How to fix this error?

Use this message to optimize the parameters for the waiting times and
for parallelization.

• What is the cause and solution for SAP error message WFCS224 - Parallel processing: Timeout for &1 (number: &2) ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WFCS224 Parallel processing: Timeout for &1 (number: &2)
  
  Meaning / Cause:
  This error occurs in the SAP Workflow system during parallel processing of workflow tasks. Specifically, it indicates that a timeout has occurred while waiting for a parallel processing step to complete.
  
  &1: Represents the object or step for which the timeout occurred.
  &2: Represents the number of the timeout or the count of attempts.
  
  In SAP Workflow, when multiple parallel tasks are triggered, the system waits for all parallel branches to complete before continuing. If one or more branches take too long or do not complete within the expected timeframe, the system raises this timeout error.
  Common causes include:
  
  Long-running or stuck workflow tasks.
  Deadlocks or resource contention in the system.
  Network or system performance issues causing delays.
  Incorrect or missing event triggers that prevent workflow steps from completing.
  Workflow container or task processing errors.
  
  
  Solution / How to Resolve:
  
  
  Check Workflow Logs:
  
  Use transaction SWI1 (Workflow Log) or SWI2_FREQ to analyze the workflow instances and identify which step or task is causing the delay.
  Look for stuck or long-running tasks.
  
  
  
  Analyze Workflow Steps:
  
  Identify the parallel branches involved.
  Check if any of the parallel tasks are waiting for user input or external events.
  Verify if any tasks are in error status or waiting for a trigger.
  
  
  
  Check System Performance:
  
  Review system performance and workload.
  Check for any database locks or deadlocks that might be causing delays.
  Monitor background jobs and update tasks related to workflow.
  
  
  
  Adjust Timeout Settings:
  
  If the timeout is too short for the business process, consider increasing the timeout value.
  Timeout parameters can be adjusted in the workflow customizing or via relevant SAP notes.
  
  
  
  Restart or Cancel Stuck Workflows:
  
  If workflows are stuck, consider restarting or cancelling them.
  Use transaction SWI2_DIAG to diagnose and manage stuck workflows.
  
  
  
  Check Event Linkage:
  
  Ensure that all events expected to trigger the continuation of the workflow are correctly configured and firing.
  Missing or incorrect event linkage can cause workflows to wait indefinitely.
  
  
  
  Apply SAP Notes:
  
  Search for SAP Notes related to WFCS224 for any known bugs or patches.
  Sometimes, SAP releases corrections for workflow timeout issues.
