Pivot log data by dates

leviavihay

Hi all,
I'm trying to use RM in a certain task in which I have (kind of) log data in the following (abstract) schema:

• ID | Date | Result

I wish to transform this table to vectors from the following structure:

• id1: [date1: result1, date2: result2, ... ]
• id2: [date11: result11, date22: result22, ... ]

[notice that the dates don't necessarily repeat between different ID's] 

Thanks in advanced

HI @leviavihay,

I propose the following "approximative" solution with the association Generate Concatenation, Pivot, Generate Aggregation operators : 

The process :
