  The SAP error message 5A428 ("Previously defined demand overlaps with current record") typically occurs in the context of demand planning or production planning within SAP. This error indicates that there is a conflict between the demand records that have already been defined and the new demand record you are trying to create or modify. Here are the details regarding the cause, solution, and related information for this error:
  Cause:
  
  Overlapping Demand Periods: The new demand record you are trying to enter has a time period that overlaps with an existing demand record. This can happen if the start and end dates of the new demand fall within the range of an existing demand record.
  Duplicate Entries: There may be duplicate demand entries for the same product and time period, which can lead to conflicts.
  Incorrect Data Entry: Errors in data entry, such as incorrect dates or quantities, can also trigger this error.
  
  Solution:
  
  Check Existing Demand Records: Review the existing demand records for the same product and time period. You can do this by navigating to the relevant demand planning transaction (e.g., MD61, MD62) and checking for any overlapping entries.
  Adjust Dates: If you find that the new demand record overlaps with an existing one, consider adjusting the start and/or end dates of the new record to eliminate the overlap.
  Delete or Modify Existing Records: If the existing demand record is no longer needed or can be modified, you may choose to delete or adjust it to accommodate the new demand.
  Consult Documentation: Refer to SAP documentation or help files for specific guidelines on managing demand records and understanding the implications of overlapping demands.
  Use Transaction Codes: Utilize transaction codes like MD04 (Stock/Requirements List) to analyze the demand and supply situation for the material in question.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD61 (Create Planned Independent Requirements), MD62 (Change Planned Independent Requirements), and MD04 (Display Stock/Requirements List).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP Notes can provide additional context or solutions that may not be covered in standard documentation.
  User Roles and Authorizations: Ensure that you have the necessary authorizations to create or modify demand records, as restrictions may also lead to errors.
  Training and Support: If you are unsure about how to resolve the issue, consider reaching out to your SAP support team or attending training sessions focused on demand planning and management.
