• What is the cause and solution for SAP error message /SAPAPO/MC01088 - Values in upper case are not unique, upper case is being reset ?

  The SAP error message /SAPAPO/MC01088 indicates that there is an issue with the uniqueness of values in upper case within the context of SAP Advanced Planning and Optimization (APO). This error typically arises when the system encounters duplicate values that are not unique when converted to upper case, leading to a reset of those values.
  Cause:
  
  Duplicate Values: The primary cause of this error is the presence of duplicate values in the relevant fields that, when converted to upper case, result in non-unique entries. For example, if you have values like "abc" and "ABC", they would be treated as the same when converted to upper case.
  Data Entry Issues: Inconsistent data entry practices can lead to duplicates. For instance, users might enter the same value in different cases.
  Data Migration: If data has been migrated from another system, it may not have been cleaned properly, leading to duplicates.
  
  Solution:
  
  Identify Duplicates: Use transaction codes like SE16 or SE11 to check the relevant database tables for duplicate entries. You can run queries to find values that are the same when converted to upper case.
  Data Cleansing: Once duplicates are identified, you will need to clean the data. This may involve:
  
  Renaming or modifying the duplicate entries to ensure uniqueness.
  Standardizing the data entry process to prevent future duplicates.
  
  
  Validation Rules: Implement validation rules in the data entry process to ensure that values are unique before they are saved in the system.
  Testing: After making changes, test the system to ensure that the error no longer occurs and that the data integrity is maintained.
