  The SAP error message UPO_IE_MSG045 ("Cannot change; Reservoir was created in UOM") typically occurs in the context of SAP's Integrated Planning (IP) or other modules where units of measure (UOM) are critical for data integrity and consistency. This error indicates that there is an attempt to change a reservoir (a data structure used for storing planning data) that was originally created with a specific unit of measure, and the system is preventing this change to maintain data integrity.
  Cause:
  
  Unit of Measure Mismatch: The reservoir was created with a specific unit of measure, and any attempt to change it to a different UOM is not allowed.
  Data Integrity Rules: SAP enforces strict rules to ensure that data remains consistent. Changing the UOM of a reservoir could lead to inconsistencies in planning data.
  Configuration Issues: There may be configuration settings in the SAP system that restrict changes to reservoirs once they are created.
  
  Solution:
  
  Check UOM: Verify the unit of measure that the reservoir was created with. Ensure that any changes you are trying to make are compatible with this UOM.
  Create a New Reservoir: If you need to work with a different unit of measure, consider creating a new reservoir with the desired UOM instead of trying to change the existing one.
  Consult Documentation: Review SAP documentation or help resources related to Integrated Planning and reservoirs to understand the limitations and best practices.
  Contact SAP Support: If the issue persists or if you believe it is a system error, consider reaching out to SAP support for assistance.
