  SAP Error Message:
  
  WS_TOOL300: Enter an identification
  
  Cause:
  The error message WS_TOOL300 typically occurs when a required identification field is left empty during a transaction or when using a tool in SAP. This identification could be a key field such as a document number, material number, user ID, or any other mandatory identifier that the system expects to be filled before proceeding.
  In other words, the system prompts this message because it needs a specific identification input to continue processing, and it was not provided.
  
  When does it occur?
  
  When executing a transaction or tool that requires an identification input.
  When a mandatory field for identification is left blank.
  During data entry screens, reports, or custom tools where identification is necessary.
  
  
  Solution:
  
  
  Enter the required identification:
  
  Check the screen or input form where the error appears and provide the necessary identification value. This could be a document number, user ID, material number, or any other key field.
  
  
  Verify mandatory fields:
  
  Ensure all mandatory fields marked with an asterisk (*) or required by the process are filled.
  
  
  Check for default values or selection criteria:
  
  Sometimes, the identification might be expected from a selection screen or default value. Make sure these are correctly set.
  
  
  Review the process or tool documentation:
  
  If you are using a custom tool or report, refer to its documentation to understand what identification is required.
  
  
  Consult with your SAP administrator or developer:
  
  If the identification is unclear or the error persists despite entering values, there might be a configuration or programming issue.
