How To Fix WT710 - Parallel processing requires the number of recipients per process

SAP Error Message - Details

• Message type: E = Error

• Message class: WT - Retail: Replenishment

• Message number: 710

• Message text: Parallel processing requires the number of recipients per process

What causes this issue?

You have chosen to use parallel processing but have not entered data
for the number of recipients per process (entry value > 0). This data
must, however, be entered before parallel processing can be used.

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?

In the input field for the number of recipients per process, enter a
value greater than 0.
Deactivate parallel processing.
For more information about this input field, see F1 Help.

• What is the cause and solution for SAP error message WT710 - Parallel processing requires the number of recipients per process ?

  Certainly! Here's detailed information about the SAP error message WT710:
  
  SAP Error Message: WT710
  Text: Parallel processing requires the number of recipients per process
  
  Cause:
  This error occurs in the Workflow (WF) module when you try to execute a workflow step or send a workflow message in parallel processing mode, but the system does not know how many recipients should be processed in each parallel process. In other words, the workflow is set up to distribute tasks or messages in parallel, but the parameter specifying the number of recipients per parallel process is missing or not maintained.
  Parallel processing in SAP Workflow allows you to send tasks or messages to multiple recipients simultaneously by splitting the recipient list into smaller groups (processes). To do this, the system needs to know how many recipients should be assigned to each parallel process.
  
  When does this happen?
  
  When using parallel processing in workflow steps or message sending.
  When the number of recipients per process is not specified or is zero.
  When the workflow container or the step configuration expects this parameter but it is missing.
  
  
  Solution:
  
  
  Specify the number of recipients per process:
  
  In the workflow step or message sending method, maintain the parameter that defines how many recipients should be processed in each parallel process.
  This is usually done in the workflow step definition or in the method call that sends the message.
  
  
  
  Check the workflow step configuration:
  
  Go to transaction PFTC (Workflow Builder).
  Open the relevant workflow step.
  Check the binding or the method parameters for the number of recipients per process.
  Make sure the parameter is filled with a positive integer value.
  
  
  
  Check the container or the method interface:
  
  If the number of recipients per process is passed via the container or method interface, ensure it is correctly set before the step is executed.
  
  
  
  Adjust the workflow logic if necessary:
  
  If parallel processing is not required, consider disabling it or changing the processing mode to sequential.
  
  
  
  
  Additional Information:
  
  Parallel processing is used to improve performance and reduce processing time by distributing workload.
  The parameter for the number of recipients per process controls the granularity of parallelization.
  If this parameter is too high, it may reduce parallelism; if too low, it may create too many parallel processes and overhead.
  This error is specific to SAP Workflow and does not occur in other modules unless they use workflow functionality.
