• What is the cause and solution for SAP error message POWLR034 - Failed to serialize the data object ?

  The SAP error message POWLR034, which indicates "Failed to serialize the data object," typically occurs in the context of SAP applications that involve data processing, such as SAP Business Workflow or SAP Process Integration (PI).
