• What is the cause and solution for SAP error message WZ313 - Error in container: ?

  SAP Error Message:
  
  WZ313 Error in container:  
  
  Cause:
  The error message WZ313 typically occurs in SAP Workflow when there is an issue with the workflow container. The container is a data structure that holds all the data objects (variables) used in a workflow. This error indicates that the workflow runtime is unable to find or access a required container element, or there is a mismatch or inconsistency in the container data.
  Common causes include:  
  
  A container element referenced in the workflow step or method does not exist or is misspelled.  
  The container element is not properly bound or passed between workflow steps.  
  The container element has an unexpected data type or is empty when it should contain data.  
  The workflow task or method is trying to access a container element that was not filled or initialized.  
  Changes in the workflow definition or task interface without updating the container bindings.
  
  
  Solution:
  To resolve the WZ313 Error in container, follow these steps:
  
  
  Check Container Elements:  
  
  Go to the workflow builder (transaction SWDD).  
  Open the workflow and check the container elements defined at the workflow level and in the individual steps.  
  Verify that all container elements referenced in the step or method exist and are correctly spelled.
  
  
  
  Verify Container Bindings:  
  
  Check the binding of container elements between the workflow and the task or method.  
  Ensure that the data types match and that the binding is correctly maintained.  
  If the container element is supposed to be passed from one step to another, verify that it is properly propagated.
  
  
  
  Check Task Interface:  
  
  If the error occurs in a task, check the task interface (transaction PFTC) to ensure the container elements are correctly defined and bound.
  
  
  
  Debug the Workflow:  
  
  Use transaction SWI1 or SWI2_DIAG to find the workflow instance with the error.  
  Use the workflow log (transaction SWI1) to identify the step where the error occurs.  
  Use the workflow debugger (transaction SWUS) to step through the workflow and inspect container contents.
  
  
  
  Correct the Workflow or Task Definition:  
  
  If a container element is missing, add it.  
  If the binding is incorrect, fix it.  
  If the data type is wrong, adjust the container element or the method interface accordingly.
  
  
  
  Test the Workflow:  
  
  After corrections, test the workflow to ensure the error no longer occurs.
