I am trying to build a transfer function with inventory as input and sales as the output. I build both functions and put the results into the Transfer Function Model Specification dialog where I get a "Transfer function model cannot be fitted. Inputs have missing values" error message. Can someone please advise?

*" Once both models are constructed, shouldn't the ARIMA values go into the Transfer Function Model Specification?"*

You would have to specify the orders of ARIMA for **both** noise series (i.e., the error term of the output series) and input series like this (See JMP documentation for details.Transfer Functions

Also note that there are a few steps preceding to this final model specification as shown below such as pre-whitening and check cross-correlations, etc.
