• What is the cause and solution for SAP error message UPP_LB026 - Manually entered or missing values were overwritten by the system ?

  The SAP error message UPP_LB026 indicates that manually entered or missing values in a certain context (usually related to planning or budgeting) have been overwritten by the system. This typically occurs in the context of SAP's Integrated Business Planning (IBP) or other planning modules where the system automatically calculates or fills in values based on predefined rules or algorithms.
  Cause:
  
  Automatic Calculations: The system has rules or algorithms that automatically calculate values based on other data inputs. If you manually enter a value that conflicts with these calculations, the system may overwrite your input.
  Missing Data: If required data is missing, the system may fill in default values or calculated values, which can overwrite any manual entries.
  Data Consistency Checks: The system may have checks in place to ensure data consistency, leading to overwriting of values that do not meet certain criteria.
  
  Solution:
  
  Review Input Values: Check the values you have entered manually to ensure they are correct and do not conflict with system calculations.
  Understand System Logic: Familiarize yourself with the planning logic and rules in your SAP system. This may involve consulting documentation or working with your SAP administrator to understand how values are calculated.
  Adjust Settings: If necessary, adjust the settings or parameters in the planning module to allow for manual entries without being overwritten. This may involve changing configuration settings or user permissions.
  Consult SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional insights or solutions specific to your version of SAP.
  Training and Documentation: Ensure that users are trained on how to enter data correctly and understand the implications of manual entries in the system.

  SAP Documentation: Refer to the official SAP Help Portal for detailed documentation on the specific module you are using (e.g., IBP, S/4HANA).
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
