• What is the cause and solution for SAP error message /SAPAPO/DMRES042 - Only the first or last day shift is allowed to extend beyond midnight ?

  The SAP error message /SAPAPO/DMRES042 indicates that there is an issue with the scheduling of shifts in the SAP Advanced Planning and Optimization (APO) module. Specifically, this error occurs when a shift is defined to extend beyond midnight, which is not allowed for certain configurations in the system.
  Cause:
  The error is typically caused by the following scenarios:
  
  Shift Configuration: The shift is configured to start before midnight and end after midnight, which is not permitted for certain planning scenarios.
  Planning Version: The planning version may have restrictions that do not allow shifts to extend beyond midnight.
  Resource Availability: The resource or capacity being scheduled may have constraints that prevent shifts from spanning across midnight.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Shift Definitions:
  
  Review the shift definitions in the system. Ensure that shifts are defined correctly and do not extend beyond midnight unless explicitly allowed.
  If a shift needs to extend beyond midnight, consider splitting it into two separate shifts: one that ends at midnight and another that starts after midnight.
  
  
  
  Adjust Planning Parameters:
  
  If applicable, check the planning parameters and settings in the APO system to see if there are any restrictions on shift timings.
  Modify the planning version settings to allow for shifts that extend beyond midnight if that is a requirement for your planning process.
  
  
  
  Resource Configuration:
  
  Review the resource configuration to ensure that the resource can handle shifts that extend beyond midnight. Adjust the resource availability settings if necessary.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on shift management and scheduling in APO. This can provide insights into best practices and configuration options.
  
  
  
  Testing:
