• Message text: Scaling can only be changed for field groups with constant unit

What causes this issue?

The system displayed records with different units for each line for
field groups with variable units. In order to avoid confusion, which
might occur if a unit is scaled in one way in one line and in a
completely different way in the next line, the scaling option is only
available for field groups with constant units.

• What is the cause and solution for SAP error message GP104 - Scaling can only be changed for field groups with constant unit ?

  The SAP error message GP104, which states "Scaling can only be changed for field groups with constant unit," typically occurs in the context of working with field groups in SAP, particularly when dealing with data elements that have scaling factors. This error indicates that you are trying to change the scaling of a field group that is not defined with a constant unit, which is a requirement for making such changes.
  Cause:
  
  Field Group Definition: The field group you are trying to modify may not be defined with a constant unit. In SAP, certain field groups are expected to have a fixed unit of measure, and changing the scaling for these groups is not allowed.
  Data Element Configuration: The data element associated with the field group may not be configured correctly to support scaling changes.
  Inconsistent Unit of Measure: If the field group is associated with multiple units of measure or variable units, SAP will prevent scaling changes to maintain data integrity.
  
  Solution:
  
  Check Field Group Configuration: Review the configuration of the field group in question. Ensure that it is defined with a constant unit of measure. You can do this by navigating to the relevant configuration settings in the SAP system.
  Modify Data Element: If the data element associated with the field group is not set up correctly, you may need to adjust its properties to ensure it supports a constant unit. This may involve changing the data element's attributes in the Data Dictionary (SE11).
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly configure field groups and data elements with respect to scaling and units of measure.
  Seek Help from SAP Support: If you are unable to resolve the issue through configuration changes, consider reaching out to SAP support or consulting with an SAP expert who can provide more specific guidance based on your system's configuration.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on field group configurations and scaling.
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and others that may help you navigate and modify the necessary configurations.
  Unit of Measure Management: Understanding how units of measure are managed in SAP can provide insights into why certain configurations are required and how to properly set them up.
  
  By following these steps, you should be able to identify the cause of the GP104 error and implement a solution to resolve it.
