  The SAP error message OIUPR833, which states "More than one MP flagged as MST default," typically occurs in the context of Master Data Management, particularly when dealing with Master Data for materials or products in SAP. This error indicates that there are multiple Master Data records (MPs) that have been flagged as the default for a specific category, which creates ambiguity for the system.
  Cause:
  
  Multiple Defaults: The primary cause of this error is that more than one Master Data record has been marked as the default for a specific material or product type. This can happen due to data entry errors, system migrations, or incorrect configurations.
  Data Duplication: There may be duplicate entries in the Master Data that have been incorrectly set up, leading to multiple records being flagged as the default.

  Solution:
  
  Identify Duplicate Records: Use transaction codes like SE16 or SE11 to access the relevant database tables and identify the Master Data records that are flagged as default. Look for the specific fields that indicate the default status.
  Review and Correct Data: Once you have identified the duplicate records, review them to determine which one should be the actual default. You may need to consult with business stakeholders to make this decision.
  Update Master Data: Remove the default flag from the duplicate records. This can typically be done through the relevant Master Data maintenance transaction (e.g., MM01, MM02 for materials).
  Check Configuration: If the issue persists, review the configuration settings in the system to ensure that the rules for default selection are correctly set up. This may involve checking the customizing settings in SPRO.
  Testing: After making the necessary changes, perform tests to ensure that the error does not reoccur and that the system behaves as expected.
