I have been running a provided ARIMA process with Windowing and Loop...runs fine.  But when I recreate this process I keep getting a Recall error...The Extract Macro and Remember and Recall are names "data" ExampleSet".  I appreciate all recommendations.  Thanks Karl

 

Main Process & Loop Sub-Process with Recall Error Message.

    Is your order of execution correct?

     

    I use this one. It has optimization. I had to change the data to protect the innocent so make sure the attribute names are correct.

    The one above has a problem, so skip that as I trouble shoot. This one below works without optimization.

    i use this one and still, i got error on recall operator

  • Thomas_OttThomas_Ott RapidMiner Certified Analyst, RapidMiner Certified Expert, Member Posts: 1,761 Unicorn

    Is your order of execution correct?

  • Edin_KlapicEdin_Klapic Employee-RapidMiner, RMResearcher, Member Posts: 299 RM Data Scientist

    Hi,

     

    you can check the actual execution order by clicking on the blue icon marked in the screenshot below.image.png

     

    As you can easily see in this example the Recall Operator is executed befor the Remember Operator which results in an error message as you described.

    In order to change ther execution order the easiest way is to click on one Operator and then select the Operator which should be executed afterwards.

    I personally recommend to rather enforce the correct execution order by connecting the output port of the Remember Operator to other Operators which are executed beforehand. In the following screenshot I simply put the Recall Operator inside the Subprocess.image.png

     

    Best,

    Edin
