Hi there,

I'm trying to build a "serial numer", but need a conditional, until today I did it using "CountRows(Filter(", but I have the problem with non delegable formulas.

So I think maybe is possible do it with Max funtion, but I don't know how I can do it.

My alternative code that I'm trying is:

Max(Filter('[dbo].[tbPO]';IdProject = proyecto).Line)+1

If not possible, How I can do it to avoid the issues with non delegable functions?

Thank you.

MAX cannot be delegated: so just use a Sort function instead. It does the same thing.

Sort(Filter('[dbo].[tbPO]';IdProject = proyecto),Line, Descending).Line+1

Note: I assume 'Line' is a number type.

Try:

Hi@mdevaney ,

Yes, you are right, "Line" is a number, but the function doesn't work:

My last function was:

@Manarjomar

I missed the FIRST function. Include this:

Sort(First(Filter('[dbo].[tbPO]';IdProject = proyecto),Line, Descending)).Line+1

Thank you @mdevaney your formula doen't work, but I understood your idea and I found that only was an order error. Finally works with this one:

If(FormPO.Mode = FormMode.New ; First(Sort(Filter('[dbo].[tbPO]';IdProject = proyecto);Line; Descending)).Line+1;DataTablePO.Selected.Line)

Thank you for your help.

Regards.

Hi @mdevaney ,

Jumping on this post in case you can help. I have created an application for customer service tickets. For each ticket there is an increasing ID per store. The code below was working fine until I loaded the database with the tickets from an old system where there is no ID. For stores where there aren't many tickets the code still works. For the ones where there are lots of tickets it is creating all the IDs as 1. I suspect this is due to delegation issues and the last ticket it is getting is one of the ones with no ID. From what I see, Sort is delegable, but Last is not. Do you have any ideas how I could rework this code so it correctly gets the last highest ID ?

I think the code is quite self explanatory but just in case: I filter the list to get tickets for the selected store, sort it by ID ascending and then take the last and add 1.
Thanks

I believe I have managed to fix this by using a collection. I first collect using Sort, Descending on the ID and then use the First(Collection).ID + 1.
