WFCS224 - Overview

• 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.

  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.
