Make mosaic dataset custom fields "allowed" using ArcPy

[JoanneMcGraw]

Hello all,

Given a file geodatabase containing a mosaic dataset, I have added and populated fields using arcpy functionality. Now, I am setting the mosaic dataset properties, but there doesn't appear to be any way to make the custom fields "allowed". There is no entry to set this property in the Set Mosaic Properties dialog in Model Builder. 

Is this not supported through automation?

Cheers,

Retired?

I don't see anything in the documentation indicating that. Is there a replacement?

That is my status

I believe I have solved my problem.

This order doesn't work:

1. Create fgdb
2. Create mosaic
3. Set mosaic properties
4. Add fields
5. etc....

But this order does:

1. Create fgdb
2. Create mosaic
3. Add fields
4. Set mosaic properties
5. etc....

I assume running the Set Mosaic Properties tool for the first time will simply make all fields that exist in the mosaic dataset "allowable" for querying. Adding the fields after having done that, doesn't update the property. And, it appears that subsequent invocations of Set Mosaic Properties doesn't either. I assume the tool recognizes whether it's ever been set previously and, if it was, it doesn't change it.

Anyway, this seems to have taken care of my problem. Hopefully, the info is of use to someone else.

Cheers!
