How to define for loop with incremental date

[#1]

Hi!

I am trying to adjust total inspection quantity per day based on the "Single Count?" column. Created a new inspection quantity column Inspected_TTL_New. If the input in this column is "F", Inspected_TTL should be same as Inspected_TTL_New. But if it is "T", Inspected_TTL_New column should be the Inspected_TTL quantity for "F" on the same day. 

This is how far I got:

inspected_ttl_temp = 0;
For Each Row(
	If( :SINGLE COUNT? == "F",
		:Inspected_TTL_New = :Inspected_TTL;
		inspected_ttl_temp = :Inspected_TTL;
	,

	);
	If( :SINGLE COUNT? == "T",
		:Inspected_TTL_New = inspected_ttl_temp,

	);
);

This is what I'm trying to do:

I tried to create a for loop below with incremental dates to capture the inspection quantity per each day but couldn't get it to work :\ 

nspected_ttl_temp = 0;
startdate = "2022-08-01";
For( i = "2022-08-01", i <= Max( :DATE ), i++,
	For Each Row(
		If( :SINGLE COUNT? == "F",
			:Inspected_TTL_New = :Inspected_TTL;
			inspected_ttl_temp = :Inspected_TTL;
		,

		);
		If( :SINGLE COUNT? == "T",
			:Inspected_TTL_New = inspected_ttl_temp,

		);
	)
);

Please help!!

Hi

My understanding is you want to get the "Inspect_TTL "about "Single Count" F. 

There is a easy way to do that just need transpose your data table.

Data Table( "jmp example data table" ) << Transpose(
	columns( :Inspected_TTL ),
	By( :DATE ),
	Label( :Name( "SINGLE COUNT?" ) ),
	Output Table( "Transpose of jmp example data table" )
);

Then you will get a new table like this. And the column F is the data.

Then Join the dt_tran to original dt.

Data Table( "jmp example data table" ) << Join(
	With( Data Table( "Transpose of jmp example data table" ) ),
	Select( :Name( "SINGLE COUNT?" ), :DATE, :Inspected_TTL, :Inspected_TTL_New ),
	SelectWith( :F ),
	By Matching Columns( :DATE = :DATE ),
	Drop multiples( 0, 0 ),
	Include Nonmatches( 0, 0 ),
	Preserve main table order( 1 )
);

final dt like this one. 

Hope this helps.

Have a good day!
