• What is the cause and solution for SAP error message WGDS_PROCESS124 - Not possible to read generic data ?

  The SAP error message WGDS_PROCESS124: Not possible to read generic data typically occurs in the context of SAP Workflow or Business Workplace when the system is unable to retrieve or process certain generic data required for workflow processing or task execution.
  
  Cause
  
  Data Inconsistency or Missing Data: The workflow or process is trying to access generic data (such as container elements, task data, or object attributes) that is either missing, inconsistent, or corrupted.
  Authorization Issues: The user or system process may lack the necessary authorizations to read the required data.
  Incorrect or Incomplete Workflow Configuration: The workflow step or task might be incorrectly configured, leading to attempts to read non-existent or improperly defined data.
  Technical Issues: Problems with the underlying database or communication errors can also cause failure in reading generic data.
  Transport or System Copy Issues: Sometimes, after system copies or transports, certain workflow objects or data may not be properly adjusted or activated.
  
  
  Solution
  
  
  Check Workflow Configuration:
  
  Verify the workflow step/task configuration to ensure that all required generic data elements are correctly defined.
  Use transaction SWDD (Workflow Builder) to inspect the workflow and its container elements.
  
  
  
  Check Data Consistency:
  
  Use transaction SWI1 (Work Item Selection) or SWI2_FREQ to find the problematic work item.
  Analyze the work item and check the container data for missing or inconsistent entries.
  
  
  
  Check Authorizations:
  
  Ensure that the user or system process has the necessary authorizations to read the data.
  Use transaction SU53 after the error occurs to check for missing authorizations.
  
  
  
  Re-Generate or Re-Activate Workflow:
  
  Sometimes re-activating the workflow or re-generating the task can resolve inconsistencies.
  Use SWU3 (Automatic Workflow Customizing) to check and fix workflow customizing.
  
  
  
  Check System Logs and Dumps:
  
  Use SM21 (System Log) and ST22 (ABAP Dumps) to find related error messages or dumps that provide more details.
  
  
  
  Transport and System Copy Checks:
  
  If the error appeared after a system copy or transport, verify that all workflow objects and customizing are correctly transported and activated.
  
  
  
  SAP Notes and Support:
  
  Search for relevant SAP Notes using the message number or keywords.
  For example, SAP Notes related to workflow container issues or generic data reading problems.
