Exporting products using Filter (multiple article numbers)

Hi All,

I am struggling (once more) with the export list. I need to export data on a specific set of products according to their article number.

Lets say these three products:
1031260
1031261
1031270

What is the delimiter to add when copying those 3 articles into the “Filter box” during the export generation. Pure copy paste is not working (would have been too easy).

I only get a filter result when I use one number only e.g. 1031260

But how will I get a search results for all 3 products?

Highly appreciate your input
Chris
