Pivot tables with 2 attributes for columns

ivangeraskin

I have table of purchases. Buyers with related Card_IDs buy diffrent products with related Segment (Cheap, Expensive) and Type (Meat, Bread, Milk)
Card_ID - Segment - Type - Amount
1012 - Cheap - Meat - 1

1012 - Cheap - Bread - 2

1013 - Expensive - Milk - 1

1013 - Cheap - Bread - 3

1014 - Expensive - Bread - 1

1014 - Cheap - Meat - 2

1014 - Expensive - Milk - 1

I want to make a pivot table, where "Card_ID" will be in string, "Segment"+"Type" in columns, aggregation sum by "Amount":
Card_ID - Cheap+Meat - Cheap+Bread - Cheap+Milk - Expensive+Meat - Expensive+Bread - Expensive+Milk

1012 - 1 - 2 - 0 - 0 - 0 - 0

1013 - 0 - 3 - 0 - 0 - 0 - 1

1014 - 2 - 0 - 0 - 0 - 1 - 1

Thank you for your help,
Ivan

Hi,

i think the easiest thing is to create a new attribute with concat(Segment,Type) and use this as the index variable.

Thank you very much!

Can you tell, which operator could make such pivot table (after concatination), aggregating by sum (Card_id in strings, Segment_Type in columns)? I can't make "pivot table" operator do such thing.

Hi,

you first use Generate Attribute to generate the Concat, then Select Attributes to remove the two attributes you just concatted and then Pivot.

Thank you) I found solution to aggregate by sum we also need Aggregate operator before Pivot Table operator.
