  The SAP error message RSCNV428, which states "You cannot modify line item dimensions," typically occurs in the context of data modeling or data transformation processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA. This error indicates that there is an attempt to change the dimensions of a line item that is not allowed due to the current configuration or state of the data model.
  Cause:
  
  Line Item Characteristics: The error often arises when you try to modify characteristics that are defined as line items in a data model. Line item dimensions are typically fixed and cannot be altered once they are set.
  Data Model Restrictions: Certain data models or InfoProviders in SAP BW have restrictions on modifying dimensions after they have been activated or used in queries.

  Solution:
  
  Review Data Model: Check the data model or InfoProvider to ensure that you are not trying to change a characteristic that is defined as a line item. If you need to change it, consider creating a new characteristic or InfoObject.
  Check Query Design: If the error occurs during query execution, review the query design to ensure that it does not reference line item dimensions that you are trying to modify.
  Data Source Settings: Review the settings of the data source or transformation to ensure that they are correctly configured and do not impose restrictions on modifying dimensions.
  Recreate Objects: If necessary, you may need to recreate the InfoObject or InfoProvider with the desired dimensions instead of modifying an existing one.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling line item dimensions in your version of SAP BW or HANA.
