i want to know how to deal with 19000 items. I need to find only items which have a certain code attached to them, update that item then include it back into the filtered list
1. i have a massive export of product codes
2. i need to change all codes which have the .MUL. in the code to the LAS code.
3. once that is done, I only want to retain owner codes which have a [login to view URL] included of LAS.
4. if it has a product code of LAS associated with an owner code, then we need to include every other line with that same owner code
