Default Multi-field entry design and reporting

I have a date field that must have its initial date kept forever, which I understand. There also needs to be a place to have multiple date entries (updates) for the same date field and each entry must be kept (either another column or two or making a sub-datasheet for multiple entries). Is there a better way to create an area for multiple entries?

Once dates are inputted (there will be some entires for the initial date and some entries for a second, etc. date), I need to run a report hat will show the most recent dates from either of the date inputs. How do I pull up the most recent dates?

   If you are programming for n dates, then you need to use a subtable. You are basically using a transaction table to capture dates that updates were made, is that correct?

   You can still create an initial date field in the main record by creating a date field, then setting its default value to Date() or Now() so that each time a record is created, it saves the date and time.

   Do you want to create subsequent dates programatically, or through some user interaction?

   As to the reporting issue, it depends on how you are storing the dates. What you might consider (and I use this) is to create a field in your date records called "IsCurrent" or similar, and make it a checkbox. Then whenever there is an update (using a form, of course,) you take the PK of the current record, and the FK to the main table, and whereever the FK of the main table and not the PK of the current record, set IsCurrent to False. Then when you run your reports, just use "True" criteria on the IsCurrent field. It's as easy as that! :D

Lemme know if you need more help.

Hi mmcdonal,

   YES,I’m trying to capture all updated dates and I'll be using a subtable to do this. I'll also use your idea of putting the initial date in the main form.

    Subsequent dates will be either hand inputted, or sometimes imported from SAP via an Excel spreadsheet. These will then go into the subtable via a subform.

    I don't understand your explanation of how you use IsCurrent. I'm still learning. Could you explain it another way?

Thanks for your help.
