Hi @Govind_Varma

Can you share the details about code.

from pyspark.sql.functions import pandas_udf, PandasUDFType

@pandas_udf(“order_id int,order_date string ,order_item_subtotal float”, PandasUDFType.GROUPED_MAP)
def sum_total(df):
_sum = df[“order_item_subtotal”].sum()
return df.assign(order_item_subtotal =_sum)

datafinal = data1.groupBy(“order_id”,“order_date”).apply(sum_total)
