Whenever I add a new data source via Python to PowerBi it refreshes all other tables with a Python source. Is there any way to stop this from happening?
here's an example of one code:
import pandas as pd
# Set location source of CSV's
data_location = 'C:/Data Sources/'
# Data source CSV names
base = f'{ data_location }BASE_DATA.csv'
latest = f'{ data_location }LATEST_DATA.csv'
customer_data = f'{ data_location }customer_data.csv'
# Load CSV's in to Dataframes
df_base = pd.read_csv(base , dtype=str, encoding='latin')
df_latest = pd.read_csv(latest , dtype=str, encoding='latin')
df_customer = pd.read_csv(customer_data , dtype=str, encoding='latin')
# Select only required columns and rename so all match
df_base = df_base[['CIDN_','CUSTOMER_NAME_']]
df_latest = df_latest[['cidn','Company Name']]
df_latest = df_latest.rename(columns={"cidn": "CIDN_", "Company Name": "CUSTOMER_NAME_"})
df_customer = df_maxim[['CIDN_','CUSTOMER_NAME_']]
# Merge and remove duplicates
TBL_CUSTOMER_DATA = df_latest.append(df_base)
TBL_CUSTOMER_DATA = TBL_CUSTOMER_DATA.append(df_customer)
TBL_CUSTOMER_DATA.drop_duplicates('CIDN_', inplace=True)
# Final output
TBL_CUSTOMER_DATA = TBL_CUSTOMER_DATA.reset_index(drop=True)
Adding this code as a data source then refreshes every other Python data source.
This is really frustrating as some of the other data sources are very large and take a long time (some can take hours) to refresh, which is exacerbated by the fact I need to connect to a VPN on the other side of the world to access them.

Hi @Anonymous ,
Please uncheck these options so that only new data sources will be loaded when you click apply.
If you want to refresh a single table, please refer to this blog:
