  The SAP error message UJW_EXCEPTION028 indicates that a bottom-up rule has been violated in the context of SAP's Integrated Business Planning (IBP) or SAP Analytics Cloud (SAC). This error typically arises during the planning process when the data aggregation or distribution does not comply with the defined rules or constraints.
  Cause:
  The violation of a bottom-up rule usually occurs due to one of the following reasons:

  Incorrect Planning Levels: The planning levels may not be aligned correctly, leading to discrepancies in the data.
  Rule Configuration: The bottom-up rules may not be configured correctly in the planning model, leading to conflicts during data processing.
  Missing Data: There may be missing data at lower levels that prevents proper aggregation to higher levels.
  
  Solution:
  To resolve the UJW_EXCEPTION028 error, you can take the following steps:
