Custom ID that counts and resets each year

[knightjl]

Relatively new to PowerApps and reaching out to the community for assistance with building a custom ID that countss the number of containers in a waste stream created annually and resets each year. 

Example: YY-WasteType-## or 20-Battery-1.  This would be the first container of batteries created in the year 2020.  Next container of batteries would be 20-Battery-2 and so on.  In 2021 the ID would be 21-Battery-1.  I have figured out how to capture the year and wastetype, but I am struggling with the last digit and how to count and reset each year.  

Writing my data from PA to a SP List.  Currently I am using the largest ID number.

First(Sort('Container Log',ID,Descending)).ID+1)

Complete code....

If(varFormMode="Edit", varContainerNo, Text(Now(),"[$-en-US]yy") & "-" & Dropdown5.Selected.Title & "-" & First(Sort('Container Log',ID,Descending)).ID+1)
 

Any suggestions on how to accomplish the yearly count and reset of the last digit of this custom container ID would be greatly appreciated.

Hi @knightjl ,

Do you want to get a text like this "20-Battery-1"?

If so, since you want to reset ID every year, you need to filter firstly. Also, since the ID number that you want is not directly equal to ID

 field, I suggest you use CoutRows() to represent number.

Try this formula:

Concatenate(Text(Year(Now())),
            "-",
            Dropdown5.Selected.Title,
            "-",
           Text(
                CountRows(
                          Filter(fruit11111,Year(Created)=Year(Now()))
                          )+1
                )
            )

On your side, you should try:

If(varFormMode="Edit", varContainerNo,
   Concatenate(Text(Year(Now())),
            "-",
            Dropdown5.Selected.Title,
            "-",
           Text(
                CountRows(
                          Filter('Container Log',Year(Created)=Year(Now()))
                          )+1
                )
            )
)

Thank you for your reply.  I tried using the CountRows function, but this function cannot be delegated so I get a Delegation Warning.

Also note: the Custom ID is dependent upon the Waste Type (ie. Batteries, Aerosols, Solvents) selected.

Close, but this is not the solution we are looking for.  Any other ideas?

Hi @knightjl ,

Well, I don't think only using delegate function could achieve the feather that you want.

Because you want to reset ID per month, after you filter based on month, how could you know how many records has existed with the value of current month?

That needs CountRows() function.

While there's no delegate function with the feather of counting number.

The delegate functions:

Item	Number	Text	Boolean	DateTime	Complex [1]
Filter	Yes	Yes	Yes	No [4]	Yes
Sort	Yes	Yes	Yes	Yes	No
SortByColumns	Yes	Yes	Yes	Yes	No
Lookup	Yes	Yes	Yes	No	Yes
=	Yes	Yes	Yes	No [4]	Yes
<, <=,<>, >, >=	Yes [2]	No	No	No	Yes
StartsWith	-	Yes	-	-	Yes
IsBlank	-	No [3]	-	-	No

So if your records are smaller than 2000, just leave the delegation warning alone. You just need to change the delegate limit to 2000.

 If your record is larger then 2000, please consider save your data to collection.

Then using the formula that I suggested in collection.

Collection does not have delegate problem.
