Hi manoj_0911 ,

You can follow below steps to solve this :

1. Use a Wired Ethernet Connection .

2. Reconnect VPN Fresh before opening Power BI.
3. Split Query: Limit the size of data from IVR_SUBHOUR_V using filters or parameters (e.g., only current month).
4. Check Query Timeout Settings:

• Go to Data Source Settings in Power BI.

• Click Change Source > Advanced options, and increase Command Timeout to 10+ minutes.

5. Client-Side Configuration

• Power BI Desktop Options:

  • Go to File → Options and settings → Options → Data Load. Under Global → Data Load, increase Background Data Timeout to higher value.
