I have the following question:
In one column I have 150 rows with product names (all different). I have assigned an index from 0 to 2 in another column (50 rows/products per index). In a second table I have the same product names, but they are contained several times. Now I want to assign the same index from table 1 to the same product names in the second table. I don't know how to assign the same index if the product name is contained several times.
Thank you very much for your help.
