This error typically arises when you are trying to create or modify a chart in SAP BusinessObjects or SAP BW (Business Warehouse) that uses incompatible chart types together.
  Cause:
  The error occurs when:
  
  You are trying to combine different chart types that are not compatible with each other. For example, combining a bar chart with a line chart in a way that the data representation does not make sense.
  The data series or dimensions used in the chart do not align properly with the selected chart types.
  The chart configuration settings are incorrect or not supported by the selected chart type.
  
  Solution:
  To resolve the RSWWW401 error, you can take the following steps:
  
  
  Check Chart Types: Review the chart types you are trying to combine. Ensure that they are compatible. For example, if you are using a combination chart, make sure that the primary and secondary axes are set up correctly.

  Simplify the Chart: If the combination of chart types is not essential, consider simplifying the chart by using a single chart type that can adequately represent the data.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on chart combinations and supported configurations.
  
  
  Test with Sample Data: If possible, create a test chart with sample data to see if the issue persists. This can help isolate whether the problem is with the data or the chart configuration.
