Problem with loop modelling output saving

Sample Data

Hi @sebastian_gonza,

Can you check your XML file : It seems to be broken (it can not be loaded in RapidMiner)

Hi,

attached is a solution. You need Operator Toolbox extension to run this.

Best,

Martin

Thank you Martin

Sorry one last thing, I tried using "Append" operator to join all the model results in a table but it only allows a table to be joined, also I cant append the IDclient to each model, could you help me please?

Thank you

Hi,

i think Annotate is the way to go here.

BR,

Martin

Sorry, I could not ad the IdCliente to each model with annotate, I set the parameters 

Annotation name = Comment

Annotation value = IdCliente

But no specific model has the IdClient append to the IOObject

Should it be another annotation name?

@sebastian_gonza,

did you use macros? Attached a version with annotate.

Cheers,

Martin
