# Sum by group

Hello,

I would like to group the unit values ​​of the products regardless of the order of the document: When changing the price order, calculate this way, as the formula is as follows: =IF(C3=C2;"";SUMIF(C:C;C3;E:E)) In this formula, the DOCUMENT column is considered to perform the sum, but I need to use the DOCUMENT and SUPPLIER column, to then consider the sumif. I ask for a formula suggestion to solve my problem.

Grateful.

I'd create a pivot table based on the data.

# Re: Sum by group

My preference when aggregating data by group is to create a new table that lists the unique combinations of attributes that define the group. # Re: Sum by group

Thanks for your return. However, I need to retain the structure of the first image attached in my question, this is a block of a much larger spreadsheet. And according to the second image, even if the supplier and the documents are in disarray, I need it according to the first image. Thank you for your concern to help me.

That is just a bit more complicated.  Would you want to display the total against the first member of each group or the last? A start towards a solution was to be found to the right of the previous spreadsheet.

``````= HSTACK(
product,
MAP(product, LAMBDA(currentInstance,
LET(
firstOccurence, XLOOKUP(currentInstance, product, product,,,1),
showTotal?,     ISREF(currentInstance firstOccurence),
IF(showTotal?,  SUMIFS(UnitValue, product, currentInstance), "")
)
))
)``````

First or last depends upon the final parameter of the XLOOKUP but, as it stands, the match is made on the basis of a single attribute (product) rather than two (supplier and document).

@peter Bartolomeu I believe that the problem is in =(IFC3=C2;""; which needs to consider the document and the supplier (even if out of order) to then apply the second part of the formula SUMIF(C:C;C3;E:E) ), to then maintain the structure of the first image of the question.

# Re: Sum by group

I have put together a solution to what I understand to be your problem.  All of the methods it uses are specific to Excel 365 and I am not sure you are a 365 user.  Also I suspect my approach to problem solving in Excel will be alien as far as you are concerned.  If so, it may be that @Hans Vogelaar could offer something closer to you needs. ``````= MAP(supplier, document, LAMBDA(currentSupplier,currentDocument,
LET(
firstOccurence, XLOOKUP(1, (supplier = currentSupplier) * (document = currentDocument), supplier,,,1),
showTotal?,     ISREF(currentSupplier firstOccurence),
IF(showTotal?,  SUMIFS(UnitValue, supplier, currentSupplier, document, currentDocument), "")
)
))``````

# Re: Sum by group

A "traditional" formula for F5 could be

=IF(COUNTIFS(B\$4:B5,B5,\$C\$4:C5,C5)=1,SUMIFS(E\$4:E\$1000,B\$4:B\$1000,B5,C\$4:C\$1000,C5),"")

Fill down. See the attached workbook, using @Peter Bartholomew's example.

# Re: Sum by group I think that will match the OP's expectations somewhat better!
