Summarising rows in calculated table
Hi All,
Stuck on an issue that I'm almost certain is a simple one.
I have two tables of data, and I've taken them to a single calculated table via a UNION, like so:
CalcTable = UNION(
SELECTCOLUMNS(Table1, "ID", [ID], "Qty A", [Quantity], "Qty B", 0),
SELECTCOLUMNS(Table1, "ID", [ID], "Qty A", 0, "Qty B", [Quantity])
}
This has given me something like the following:
| ID | Qty A | Qty B |
| 1 | 12 | 0 |
| 1 | 0 | 10 |
| 2 | 0 | 20 |
| 2 | 6 | 0 |
| 3 | 9 | 0 |
What I'm looking to end up with is:
| ID | Qty A | Qty B |
| 1 | 12 | 10 |
| 2 | 6 | 20 |
| 3 | 9 | 0 |
I thought the function for this was SUMMARIZE, but this appears to have no effect on the data.
Thanks for any ideas!

Something like this should work for you.
Calc_table= VAR inTempTable= UNION( SELECTCOLUMNS(Table1, "ID", [ID], "Qty A", [Quantity], "Qty B", 0), SELECTCOLUMNS(Table1, "ID", [ID], "Qty A", 0, "Qty B", [Quantity]) ) RETURN SUMMARIZE ( inTempTable, inTempTable[ID],"Total Qty A",SUM(inTempTable[QtyA]),"Total QtyB",SUM(inTempTable[QtyB]))Thanks

Hi Raj, thanks for the help.
I've tried the suggested, but when attempting to SUM(inTempTable[QtyA]), PowerBI refuses.
Error:
Table variable "inTempTable" cannot be used in this context because a base table is expected.
The only fields it gives me access to in the SUM() are from other tables.
Thanks.
HI ziqh
The UNIOIN function just combines teh data and it wont aggregate, so the output of UNION is expected one.
For your desired result, you need to Wrap your UNIONed query with a SUMMARIZE function.
Thanks
