Newbie - Collecting portal's latest data.
I am a beginner just starting to use Filemaker Pro 11 and I have a issue that I need your advice.
I have created a main table with all the items in my inventory (which also includes the cost of the items). Due to the fluctuating freight charges, all the items in my inventory will have different costs from time to time. So I created another layout which I named "Item info". This layout is used to present the information for each individual item. Also, this layout includes a portal which lists out all the costs and the date of purchase throughout the life of this item. I have created a field in this layout to collect the latest purchase cost from portal. But I am not sure how to do it. Therefore, I would like to seek your advice on what is the best way to go about doing this.
Thank you for your attention.
