Dear community friends,
I have spend more then 10 days on this issue, but my badluck still working for solution.
Issue :
Formula.Firewall: Query 'Flow Main (2)' (step 'Invoked Custom Function') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.
Source :
1. Tabular Cube [ Table1,Table2]
2. OLE BD function.
Pulling dta into OLE DB connection from Tabular cube with paramater to populate data.
Step 1:
Createing dataset from Tabular with merging Table1 and Table2.
Step 2:
Created function using OLE DB with paramater.
Step 3:
Created refrence of the Step 1 and used Invoke function (Step 2 function) to get data.Here is the place am getting this error.
Formula.Firewall: Query 'Flow Main (2)' (step 'Invoked Custom Function') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.
Note :
I can't ignore the privacy policy from settings.
Hi @Baskar,
Based on my test, I can reproduce a similar error as yours. Clearly we cannot combine an external data source with another query. Please check the blog to solve your issue.
At first, I create a parameter that contains file path/name and let the source is equal to the parameter. Then the M code is like this.
let Source = Folder.Files(Parameter1), #"Invoke Custom Function1" = Table.AddColumn(Source, "Transform File from C (2)", each #"Transform File from C (2)"([Content])), #"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}), #"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File from C (2)"}), #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from C (2)", Table.ColumnNames(#"Transform File from C (2)"(#"Sample File (2)"))), #"Changed Type" = Table.TransformColumnTypes(#"Expanded Table Column1",{{"Source.Name", type text}, {"ID", Int64.Type}, {"name", type text}}), #"Merged Queries" = Table.NestedJoin(#"Changed Type",{"name"},#"Transform Sample File from C",{"name"},"Transform Sample File from C",JoinKind.LeftOuter) in #"Merged Queries"
And based on the above blog, I take the steps and change the M code as below.
let Source = testlist, #"Invoke Custom Function1" = Table.AddColumn(Source, "Transform File from C (2)", each #"Transform File from C (2)"([Content])), #"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}), #"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File from C (2)"}), #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from C (2)", Table.ColumnNames(#"Transform File from C (2)"(#"Sample File (2)"))), #"Changed Type" = Table.TransformColumnTypes(#"Expanded Table Column1",{{"Source.Name", type text}, {"ID", Int64.Type}, {"name", type text}}), #"Merged Queries" = Table.NestedJoin(#"Changed Type",{"name"},#"Transform Sample File from C",{"name"},"Transform Sample File from C",JoinKind.LeftOuter) in #"Merged Queries"
Then we can get the result without no issue. If you still get errors, please share your Power Query code here.

Thanks for your response @v-frfei-msft.
Here i have to use invoke function to get data from OLE DB connection. It is PI source.
Hi @Baskar,
I can only refer to the link that @v-frfei-msft has given as well: https://www.excelguru.ca/blog/2015/03/11/power-query-errors-please-rebuild-this-data-combination/
You have to re-structure your queries accordingly.

@ImkeF @v-frfei-msft i have followed the link but still am getting same error.
Here i have attached my flow diagram.
My source is SSAS.
1. CT_1 ans PI Tags are two different DAX code.
2. Mergeing this two dataset to create Merge1 step.
Here am trying to invokle my PI function.
@MarcelBeug can you please help me on this case
