On executing the below query to connect Excel and powerapp:
LookUp(ABCD,'Number' = First(PowerBIIntegration.Data).'Number')
ABCD is the name of the table in Excel, Number is the column.
ABCD has 2 columns Number and User Comments
We are getting an Error: when trying to retrieve data from the Network :Expression: "Number eq null not supported "
Please suggest how to handle this null?
