• What is the cause and solution for SAP error message WK209 - No columns selected to filter ?

  SAP Error Message:
  
  WK209 - No columns selected to filter
  
  Cause:
  This error occurs in SAP Workflow when you try to define or execute a workflow step that requires filtering on table columns, but no columns have been selected for the filter criteria. Essentially, the system expects you to specify which columns should be used to filter the data, but none were chosen.
  This typically happens in the context of workflow container elements or when using the workflow step "Start Condition" or "Rule" where filtering on table data is necessary.
  
  Explanation:
  
  In SAP Workflow, when you want to filter entries from a table (e.g., a table container element), you must specify which columns (fields) to use as filter criteria.
  If you leave the selection empty, the system cannot apply any filter and throws the error WK209.
  This is a safeguard to prevent workflows from running without proper filtering, which could lead to incorrect or excessive data processing.
  
  
  Solution:
  
  
  Select Columns for Filtering:
  
  Go to the workflow step or rule where the filter is defined.
  Ensure that you select at least one column (field) from the table to be used as a filter.
  This is usually done in the filter condition or in the container element assignment.
  
  
  
  Check Workflow Container Elements:
  
  Verify that the container element you are filtering on is correctly defined as a table type.
  Make sure the columns you want to filter on exist and are correctly referenced.
  
  
  
  Adjust Filter Conditions:
  
  If you are using a rule or condition to filter table entries, open the condition editor.
  Add the necessary columns and specify the filter values or conditions.
  
  
  
  Test the Workflow Step:
  
  After selecting the columns, test the workflow step again to ensure the error no longer appears.

  Common Scenario:
  
  When using a table container element in a workflow step, you might want to filter the entries based on certain criteria (e.g., only process items where status = 'Open'). If you forget to select the column "status" for filtering, the system will raise WK209.
