let
// Combine the tables into a single source
Source = Table.Combine({#"South Metro", #"Great Southern", #"South West"}),

// Change types for specific columns and handle invalid data
#"Changed Type3" = Table.TransformColumns(
Source,

{"Job", each if Value.Is(_, type text) then _ else null, type text},
{"Contract Code", each if Value.Is(_, type text) then _ else null, type text},
{"Price", each try Number.From(_) otherwise 0.0, type number} // Handle Price column
}
),

if [Status] = "Completed" then "No"
else if [Status] = "Cancelled" then "No"
else if Date.From(DateTime.LocalNow()) > [KPI Date] then "Yes"
else "No",
type text),

#"Added Custom4",
{
{"Issue Month Sort", each try Number.From(_) otherwise null, Int64.Type},
{"ECD Month Sort", each try Number.From(_) otherwise null, Int64.Type}
}
),

// Add This week Issue Date? column
#"Added Custom5" = Table.AddColumn(#"Changed Type", "This week Issue Date?", each Date.IsInCurrentWeek([Issued Date])),

// Change type for This week Issue Date? column

// Diagnostic step to check Turnaround Time values

// Add Turnaround Time Bucket column with refined error handling
#"Added Custom9" = Table.AddColumn(#"Diagnostic Turnaround Time", "Turnaround Time Bucket", each

Hi @Ankuurpaandey ,

According to the M code you provided, your source is obtained by combining multiple tables, and you combined them first and then changed the data type. Please try to process the data type in the original table first, and then combine it.

If there is still a problem after modifying and combining, please provide a specific error screenshot. I need to know which step or line the error occurred in.

Best Regards,
