RPUGEN013 - Details

• The SAP error message RPUGEN013 indicates that an additional process cannot be started for a specific function module (FM) because of missing resources. This typically occurs in the context of background processing or when trying to execute a function module that requires certain resources (like memory, processes, or system capacity) that are currently unavailable.
  Causes:
  
  Resource Limitations: The system may have reached its limit for background processes or dialog processes. This can happen if there are too many jobs running simultaneously.
  
  Configuration Issues: The system configuration may not be set up to allow for the required number of parallel processes for the function module.
  System Performance: High system load or performance issues can lead to resource contention, making it impossible to allocate the necessary resources for the function module.
  Locks: If the function module is trying to access a resource that is currently locked by another process, it may not be able to start.
