  SAP Error Message:
  
  WSTB018 Entry for day (&1) has wrong format
  
  Cause:
  This error occurs when an entry for a specific day in a time sheet or attendance/absence recording has been made in an incorrect format. The system expects the day entry to follow a particular format (usually numeric or a specific code), but the input does not conform to this expected format.
  Common causes include:  
  
  Entering non-numeric characters where numbers are expected (e.g., letters instead of digits for hours or days).  
  Using an incorrect date or day format that the system cannot interpret.  
  Data input errors in time sheet or attendance infotypes (e.g., IT2001, IT2011).  
  Incorrect manual entries or data upload files with wrong formatting.
  
  
  Solution:
  
  
  Check the Input Format:
  
  Verify the format of the day entry in the time sheet or attendance record. Ensure it matches the expected format (usually numeric, e.g., number of hours or days).
  
  
  Correct the Data Entry:  
  
  If entering data manually, correct the entry to the proper format.  
  If data is uploaded via interfaces or batch input, check the source file for formatting errors and correct them.
  
  
  
  Use Standard SAP Transactions:
  
  Use standard SAP transactions for time entry (e.g., CAT2, PA30) to avoid format issues.
