Create/ Calculate new example

Peter_MPeter_M Member Posts: 3 Learner I
I have a data set like this:
Value | Nr.
X | 1
Y | 2

And like to have this kind of data set:
Value | Nr.
X | 1
Y | 1
Y | 1

How can I generate new examples from the existing one? Do I need to use transpose to generate new Attributes? Or should I use De-Pivot or a Macro? What is the most effective way?

Thanks for help.

    If it is always the same example you want to add, then Create ExampleSet and Append seems good, no?

    thanks for the reply but I think I forget some details. There are much more existing attributes and examples. They are compressed in the way that the nr. is the sum of existing examples. I like to get the origina data set. That mean I need to copy the example like the amount of "Nr.". To make it unique I should insert a atribute.
    Hopefully you get my issue.

    Thanks in advance,

    that works for a less number fo examples (rows). Now I will check to automate this via a macro or a loop because there are a lot of rows how are need to multiplyed and appended, depending of the multiplier which is mentioned in the attribute.

    Thanks for the help,
