• What is the cause and solution for SAP error message /SAPAPO/SCC303 - Entry already made or time intervals overlap ?

  The SAP error message /SAPAPO/SCC303 Entry already made or time intervals overlap typically occurs in the SAP Advanced Planning and Optimization (APO) module when there is an attempt to create or modify a planning entry that conflicts with existing entries. This can happen in various contexts, such as during the creation of a production order, a planned order, or when managing stock levels.
  Cause:
  
  Duplicate Entries: The error indicates that there is already an existing entry for the same time period in the system. This could be due to a manual entry or an automated process that has already created a record for that time slot.
  Overlapping Time Intervals: The time intervals of the new entry you are trying to create overlap with those of an existing entry. This can happen if the start and end times of the new entry fall within the range of an existing entry.
  Configuration Issues: Sometimes, the configuration settings in the APO system may not allow for overlapping entries, leading to this error.
  
  Solution:
  
  Check Existing Entries: Review the existing entries in the relevant planning book or data view to identify any overlapping or duplicate entries. You can use transaction codes like /SAPAPO/SDP94 (for planning book) to check the entries.
  Adjust Time Intervals: If you find overlapping entries, you may need to adjust the time intervals of the new entry you are trying to create. Ensure that the new entry does not overlap with existing ones.
  Delete or Modify Existing Entries: If the existing entry is no longer needed, consider deleting it or modifying it to free up the time slot for the new entry.
  Consult Documentation: Review the relevant SAP documentation or help files for specific guidelines on managing entries in the APO system.
  Check Configuration: If the issue persists, consult with your SAP Basis or APO configuration team to ensure that the system settings allow for the desired planning scenarios.
