  The SAP error message FE157, which states "Filter across a time dimension," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is an issue with how time-based filters are applied in a query or report. This error indicates that the filter criteria applied to a time dimension (like a date or time field) are not compatible with the data model or the way the query is structured.
  Cause:
  
  Incompatible Filters: The filters applied to the time dimension may not align with the data structure or the characteristics of the time dimension in the InfoProvider.
  Missing Time Characteristics: The time characteristics required for the filter may not be included in the query or the data model.
  Incorrect Query Design: The query may be designed in a way that does not support filtering across the time dimension, such as using non-time-related fields in conjunction with time filters.
  Aggregation Issues: If the query is trying to aggregate data over a time dimension without proper handling of the time characteristics, it can lead to this error.
  
  Solution:
  
  Review Filters: Check the filters applied to the time dimension in the query. Ensure that they are valid and compatible with the data model.
  Include Time Characteristics: Make sure that the necessary time characteristics (like year, month, day) are included in the query definition.
  Adjust Query Design: Modify the query to ensure that it properly supports filtering across the time dimension. This may involve restructuring the query or using appropriate key figures.
  Check Aggregation Settings: Ensure that the aggregation settings in the query are correctly configured to handle time-based data.
