factorDatasetstring

The database to which the factorDataset factor belongs. This field is used in conjunction with factorType. If factorType is 1, the data name of the factor is displayed. If factorType is 2,factorId indicates the ID of the referenced product. If factorType is null,factorId is meaningless. This field is a new field. Old data may not have data in this field and is displayed as "/".

/
percentdouble

The percentage. Four decimal places are retained and 31.4000 is returned to indicate the percentage 31.4%. The first level returns null; The second level returns the current process as a percentage of total emissions; the third level returns the current inventory as a percentage of total emissions.

factorstring

The value of the factor. Only the third level is not empty. The factor in the inventory information indicates the factor value of the selected factor. The factor value is kept to four decimal places after the decimal point, and "1.0000" indicates that the factor value is 1. The factor value should be used in combination with factorUnit. If factorUnit is "kg CO2-Eq mg/kg", it means that the carbon emission per 1kg of the list is 1kg CO2-Eq.
