Sheet1​


So hopefully this simplified sample data will work.
Inventory Data
Columns A,B,C Represent inventory data with a crop serial number (column A), Item Number (column B) and crop quantity (Column C).
Crop serial numbers (column A) are unique and are date based so that lower number means earlier date = older crop.

Order Data
Columns E, F G are orders we have against the inventory in the first three columns.
Again, we have Item number (column E), Ship date (column F), Quantity ordered (column G)

My goal is to identify the oldest crop number that will have a quantity available for a given order if we fill these orders using oldest crops to fill earliest orders for a given item.

So for the order for Item A going out on 1/6/19, my desired formula would return "12" because all crops of Item A Older than (lower crop number than) 12 are needed for earlier shipping orders. (Adding all orders before 1/6 totals 280. Crops before 12 for column A total 240)

The orders and the Inventory are actually on separate sheets of the same workbook and are different lengths.
Neither the orders nor the crops will always be sorted by date. There are some dates where multiple orders of the same item will ship. At this point I am just looking for the oldest crop that will have any inventory left at a given order date before anything ships on that date.

Somehow I feel like I've done something like this before, but can't quite put my finger on it...

Thanks in advance!

Whats the difference between CONCAT and CONCATENATE?
The newer CONCAT function can reference a range of cells. =CONCATENATE(A1,A2,A3,A4,A5) becomes =CONCAT(A1:A5)

Ok, Let's see if I can simplify this...

Sheet2​
What I really want is to identify the oldest crop available to make up a specified sum.

The crop numbers in Table 2, column A are exclusive and age related - the lower the number, the older the crop of a particular Item. So to start the year, we have a total of 550 "A" Items on inventory. That appears in column H of table 1. All 550 are available to pull for this first order. The second order of "A" items only has 460 to choose from because the first order is presumably gone.

What I want is to identify in column I the oldest (smallest) crop number that will still have inventory left in it by the time we get to the ship date for any given order. Now, we may have multiple orders of the same item going out on the same date, but we'll deal with that later. I simply want to match the oldest available crop with inventory in it to an order date.

Any ideas?

Thanks!

The INDIRECT("1:20") represents the upper number of crops you have.

Thanks, Eric, for helping me with this. So if I am understanding right, the 1:20 just assumes I have 20 or fewer crop lines for a given item, or does it mean the serial numbers themselves are lower than 20?

My actual crop numbers are 6 digits long. I just used small numbers for simplicity. But I would be well within the 20 crops available parameter...

If the lowest serial number in your list is 123456, and the highest is 234567, then use INDIRECT("123456:234567"). You'd want to use the smallest range you can, since the more numbers the formula has to check, the slower the formula will be.

Thanks, just got it working using a minifs and maxifs to set the range. Works Great! Thank you very much!
