Applying variable data with duplicate values?

[tlambiam]

I've been asked to take some product images and apply a part number text overlay to the image and am using variable data sets to automate the process.

One part can have, multiple images, and its proving to give me problems when exporting the final assets.

When I export the assets, I setup the file to be named with the "data set name", and "data set number" but Photoshop is disregarding the duplicate variable (in this case the part number) and apply a generic "Data Set" value to the filename instead. So if I have two images of Part# 1234, the variable is correctly applied to both images, but on filename is only correct on one of the images.

Is there anyway to setup my dataset so that it does not overwrite duplicated values?

I do not believe it is possible to have multiple layers in a Data Driven Graphic template that  define the same variable name.  Variable  Names need to be unique. Each column in a CSV file relates to a single variable and layer.  I would think that Rows can have duplicate data  for different columns. If you have two images for a part the template would need two images layers or  you would need to populate the template twice for each part that has two images create two output files.  I have never use Photoshop Data Driven Graphic.  However I have done some programming  declaring two global variable with the same name would not be possible the would generate an error.
