Setting one input parameter for several models?

Question

I have a bunch of models (about 20) in my custom toolbox. I need to run them one after another and look for some errors which they make in table. I could put all these models into one but it is not allowed for my tasks. Nevertheless, I want to ease this work just by making a tool which sets a certain path to my geodatatbase in all models I need to run.

All my models have input parameter of workspace which is GDB base with "Model Parameter" label. After I set this parameter by showing the path to gdb file, I run the model. When process is done I open another model and have to set this path again. After the my current geodatabase is scanned for errors, I bring another base, which also has to be checked with that models. I haven't found yet a tool in System toolbox for automatic setting of input parameters in models.

It sounds like you are saying that using submodels is not permitted within your environment. That seems restrictive, but assuming that it is a mandatory requirement what I would do is:

1. Create a table with one text field and one row and edit it to hold the path to your data.
2. At the start of your models use a Get Field Value tool to read that value into a variable whose name you can then put between percentage signs in the remainder of your model.

The Get Field Value tool gets the value of the first row of a table for the specified field.

If you want to use a different path all you need to do is Start Editing that table and type over the old path with a new one. Nothing will need to change in your models.
