How can i roll up value so that it shows only the latest one?

Hi @kennypurnomo

There might be a easier way of doing this, but it works.

Create a rollup field in your Invoice table, refering to your Invoice Log table; choose the Last Modified field and MAX(values) in the formula field. This will give you the most recent date.

Create a lookup field in your Invoice Log table, looking up that most recent date.

Create a formula field next to it: IF(lookup field=Last Modified, Invoice No.). This will show you the invoice number when it matches the most recent date and leave the other cells blank.

Create a lookup field in your Inventory table for this formula field. It will only show your most recent Invoice Number.

Thank you. It works like a charm!

There's a simpler way of doing this now. Use a Lookup field and select option "Limit the number of items shown." Then, "Last 1."
