• What is the cause and solution for SAP error message OQ_C029 - Field changed from & to & (copied from access sequence) ?

  The SAP error message OQ_C029 indicates that a field in the access sequence has been changed from one value to another, which is not allowed in the context of the operation being performed. This error typically occurs in the context of pricing or condition records, where certain fields are expected to remain consistent based on the access sequence defined in the system.
  Cause:
  
  Access Sequence Configuration: The error often arises when there is a mismatch in the values of fields that are being copied from the access sequence. This can happen if the access sequence is configured to pull values from certain fields, and those fields have been altered in a way that violates the expected logic.
  Data Inconsistency: If there are inconsistencies in the data being processed (e.g., condition records, pricing conditions), it can lead to this error.
  User Input: Sometimes, user input during the transaction can inadvertently change a field that should remain constant, triggering this error.
  
  Solution:
  
  Review Access Sequence: Check the access sequence configuration in the relevant condition type. Ensure that the fields being referenced are correctly set up and that their values are consistent with what is expected.
  Check Condition Records: Review the condition records for the relevant pricing or condition type. Ensure that the values in the fields are correct and consistent with the access sequence.
  Data Validation: Validate the data being entered or processed to ensure that it adheres to the expected formats and values. This may involve checking for any recent changes made to the data or configuration.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the access sequence and condition records related to the error.
  Debugging: If the issue persists, consider using debugging tools in SAP to trace the execution and identify where the field value is being changed unexpectedly.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like VK11 (Create Condition), VK12 (Change Condition), or VK13 (Display Condition) to manage condition records.
  Access Sequence Maintenance: Use transaction code V/07 to maintain access sequences and review their configuration.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  User Exits or BAdIs: If custom logic is implemented via user exits or BAdIs, review that code to ensure it is not inadvertently changing field values.
  
  By following these steps, you should be able to identify the cause of the OQ_C029 error and implement a solution to resolve it.
