Posted on by Community Power Pla... Microsoft Employee

Is there a way to dynamically set the fields that a dataset is grouped by in a GroupBy funtion?

I'm trying to do it with an If() as with limited sucess

If(
		cbGroupClient.Value = false && cbGroupMonth.Value = true
			,GroupBy('Renewable Book Test',"Month","Customer_Group")
		,cbGroupClient.Value = true && cbGroupMonth.Value = false
			,GroupBy('Renewable Book Test',"Customer","Customer_Group")
		,cbGroupClient.Value = true && cbGroupMonth.Value = true
			,GroupBy('Renewable Book Test',"Month", "Customer" ,"Customer_Group")

Hi @Anonymous
What do you mean by 'limited success'? What is the issue?
Thanks.

PS There does not seem to be anything obviously wrong with your formula, although the syntax could be shortened. Also, there seems to be no result in case both Client and Month are false, which could be throwing PowerApps.

I think I understand the problem with setting a condition for GroupBy. The function is meant to be used to nest one Gallery into another: the child Gallery is set to the result of GroupBy.

Gallery1.Items:
GroupBy(datasource,"column1","grouped_column1")

Gallery2.Items:
grouped_column1
If Gallery2 relies on having grouped_column1 as the Item, then it will fail to populate data if grouped_column1 does not exist.

As an alternative, I would recommend using AddColumns to add a new temporary column that pulls in data from the column you want for GroupBy based on your conditions. Then use GroupBy on that temporary column:
GroupBy( AddColumns( 'Renewable Book Test', "tempcolumn",[put your conditions here] ), "tempcolumn","Customer_Group" )
You can set the child Gallery to
Customer_Group
and it would be consistent no matter the condition.
