@NicolasCadier, What you are wanting to do can be done, but not in the way you are thinking or at least not the way I am reading your question (upon entry). Anaplan does create a unique "key", the # then number, but you can't bank on that. When a list item(s) get deleted, those # numbers are now gone and can't be used. For example, let's say you have 5 members in a list ( #1, #2, #3, #4, and #5). If you delete all of the members, and then reimport them, the numbers will now be #6, #7, #8, #9, and #10, so no reusing the older numbers. When using a numbered list, it is very important to use a code, either manufactured from the source system (preferred) or one that is created in Anaplan. Since this can not be done via Anaplan Connect or via our Actions, this will need to be done via a module where your concatenate several fields together with a delimiter, and then update the list with the code. Why is this code so important? If you don't have a code on a numbered list, getting data from the list (using lookup's) is impossible because you will never know what the "hidden" number is (the #number). Please note, when you are using one of our ETL partners, like Informatica, Snaplogic, Dell Boomi, or Mulesoft, it is possible to create this "code" using their formula's and transformation processes. So, if you have don't have the code, the next question is "How do I update the numbered list". Simply create a module using that list in the Applies To. Create a line item using formula's to create the code (100_200_300) and then reimport that to the list using the member in the first column of the Action and making sure the Name (#ID) is used under the "Items unquely identified by" as seen below. Hope this helps, Rob
