How to use drived output of one tool as input in other tools in pro model

Question

Hi,

I am creating a model with my custom python tools in ArcGIS Pro 2.5

In this the first tool will generate some feature classes in the process and gives as the derived output. These will be used as inputs for second tool to do further process.

In second tool I have provided some validation to check that if the inputs are existing then onely proceed further else it will show error message that the required feature class is missing.

Both tools are working fine individually, if I run one by one. but in the model , I am seeing the error message as the features are not existing and I am not able to run the model.

I checked in the Pro help and they suggested to use Updating schema in a Python toolbox. But if I am using then individual /Model are not opening.

Please any one can suggest, how to use this with an example.

Thanks,

Arun E

They seem to give examples where it is possible.

I use scripts.  Perhaps export the models to scripts then combine the resultant might be easier

Yes Dan,

Final product is a model.

As per my understanding submodel will not work for this scenario.

Thanks for your time

Are you using a model as the final product?
