Recall Error

kamact2

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

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.

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

Thomas_Ott

Is your order of execution correct?

Edin_Klapic

Hi,

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

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.

Best,

Edin
