• What is the cause and solution for SAP error message BT636 - Choose another rule, if you start "only on workdays" ?

  The SAP error message BT636 ("Choose another rule, if you start 'only on workdays'") typically occurs in the context of scheduling or planning tasks in SAP, particularly when using the SAP Business Workflow or similar scheduling functionalities. This error indicates that the system has encountered a conflict with the scheduling rules defined for a particular task or process.
  Cause:
  The error arises when a scheduling rule is set to "only on workdays," but the start date or time specified for the task falls on a non-working day (e.g., a weekend or holiday). The system cannot schedule the task to start on a non-working day if the rule explicitly states that it should only occur on workdays.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Change the Start Date/Time: Adjust the start date or time of the task to a workday. Ensure that the date you select is a valid working day according to your organization's calendar.
  
  
  Modify the Scheduling Rule: If it is acceptable for the task to start on non-working days, consider changing the scheduling rule to allow for such occurrences. This can be done in the configuration settings of the workflow or scheduling tool you are using.
  
  
  Check the Work Calendar: Review the work calendar settings in SAP to ensure that the definition of workdays is accurate. This includes checking for any holidays or non-working days that may have been incorrectly configured.
  
  
  Use a Different Rule: If the task can be scheduled using a different rule that does not restrict it to workdays, select that rule instead.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on scheduling rules and how to configure them.
  
  
  Related Information:
  
  SAP Transaction Codes: Depending on your SAP version, you may need to use specific transaction codes to access the scheduling or workflow configuration settings (e.g., SWDD for workflow definition).
  Work Calendar Configuration: The work calendar can be configured in transaction code SCAL (for defining work schedules) or OXT1 (for defining holiday calendars).
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP administrator or support team for further assistance.
