• What is the cause and solution for SAP error message /SAPAPO/SNP168 - Not possible to create order, end date is not in SOS validity ?

  The SAP error message /SAPAPO/SNP168 indicates that there is an issue with creating an order in the SAP Advanced Planning and Optimization (APO) system. Specifically, the error states that the end date of the order is not within the validity period of the Source of Supply (SOS). This typically occurs in the context of Supply Network Planning (SNP) when the planning data does not align with the available supply.
  Cause:
  
  Validity Period of SOS: The Source of Supply (SOS) has a defined validity period, which includes start and end dates. If the end date of the order you are trying to create falls outside this period, the system will not allow the order to be created.
  Incorrect Planning Data: The planning data for the SOS may not be correctly maintained, leading to discrepancies in the validity dates.
  Master Data Issues: There may be issues with the master data related to the product, location, or the SOS itself, such as missing or incorrect validity dates.
  
  Solution:
  
  
  Check SOS Validity: Review the validity dates of the SOS in the system. Ensure that the end date of the order you are trying to create falls within the defined validity period.
  
  You can do this by navigating to the relevant transaction in SAP APO (e.g., /SAPAPO/SNP1 for SNP planning) and checking the details of the SOS.
  
  
  
  Adjust Order Dates: If the order's end date is outside the SOS validity, adjust the order dates to ensure they fall within the valid range.
  
  
  Update SOS Master Data: If the SOS validity needs to be extended or modified, update the master data accordingly. This can be done in the relevant master data transaction (e.g., /SAPAPO/SDP1 for Source of Supply).
  
  
  Check for Overlapping Validities: Ensure that there are no overlapping or conflicting validity periods for the SOS that could cause confusion in the planning process.
  
  
  Consult Documentation: Review any relevant documentation or guidelines for maintaining SOS and planning data to ensure compliance with best practices.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP APO for managing SOS and planning data, such as /SAPAPO/SDP1, /SAPAPO/SNP1, and /SAPAPO/SDP2.
  Master Data Maintenance: Ensure that master data is regularly reviewed and maintained to prevent issues related to validity periods.
  Error Logs: Check the error logs or messages in the system for additional context or related issues that may need to be addressed.
  
  By following these steps, you should be able to resolve the error and successfully create the order in the SAP APO system.
