Get previous value of a parameter in Tableau

Let us assume that we have defined the following parameter
Now, user can select a value for Data_Selekcja parameter, for example '2018-01-01'. Is there a way of getting the previous value from the list? Previous value would be '2017-07-01' in this case. I need the previous value of this parameter in a calculated field. The current value in a calculated field is given by [Parameters].[Data_Selekcja], but what about the previous value from the list.

Jaspersoft Studio: Force input parameter of subreport to be entered manually

In my main report I get a (small) list of string values from the data base. I then want to use this list for selecting records in a subreport, along with other input parameters:
The user shall be able to select records based on a range of begin and end date -- this is easy using an input parameter of type java.util.Date with "Is For Prompting" set to true. Another criteria shall be one or more items from a list showing values from a data base field. I could define the list in the report template, but then I'd have hard-coded strings (filled from the data base, but at definition time only).
Now the dilemma is: If I define the input parameters in the main report, I cannot get the values for the list beforehand; if I define them in the subreport, I get no prompt at all, so there's no way to set any of them.
So the report requires values for start and end date, and a list of string values to select from (multiple itmes can be selected). This list shall be built from values from the data base. In the subreport all these values shall be joined into a filter for the records. A user shall be able to define the dates and select items from the list manually before executing the report.
Is there a way to achieve this?
After some more hours of trial & error, and some more research, of course, I found that the keyword is "Query-based Input Controls". This documentation describes their creation on the JasperReports Server. Such input controls can be edited in Jaspersoft Studio as well, however, they actually work on the server only. Anyway, this is the solution to my problem.

apex tabular form icon link column

I am working with a wizard-generated Tabular Form column that needs to display an icon which launches a Javascript function and pass the row value into the function when clicked. The function launches a popUp2 window which sets the values of other fields on that row. So the row number is crucial, but it is always 0 for newly-created rows (in APEX 4.0.0.00.46). I managed to solve that problem by storing the rowNum of new rows into my Updated By column during AddRow.
What I have now is an Updated By column ("Lookup" Heading) which stores the row number of new rows, has onClick="javascript:usePopup(this);" in the Element Attributes which launches the popUp window function, and then gets any values under 2 digits wiped before submit. This fills the correct fields and submits to the table with no problem.
I can't keep using the Updated By column for this function, though. There are currently reports running on this table, so I can't add a new column to the table. I need a dummy column to display the icon, temporarily store the Row Number of newly created rows, and not mess up the MRU. It is f08, so the value of f08_0005 needs to be 0005. I tried making a null column with
select
"FUEL_USAGE_DETAIL_ID", ...
"EXPENSE_TO_PROJECT",
"EXPENSE_TO_TASK",
NULL Lookup,
"UPDATED_BY",
"PROVIDER"
from "#OWNER#"."FUEL_USAGE_DETAIL"
but that can't submit. I get the Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "01A949FAF0B3A91914ECACCDC9BBA9E6", item checksum = "B6ADF86455B14EF691B2AFB314926A0D".
Please help me create a null column to display this icon, store the row number of all the rows (including the brand new rows), and not mess up the MRU. If you need pictures of what I have and what I need, see my other thread: https://community.oracle.com/thread/3649771 Thank you!
Fractal65,
Do not add any null column in tabular form.
just go to>>Edit tabular form attribute make following change
you will get it position as f02_000X (x-rownum)
now uou can use this rownum value in javascript or anything.
Hope this helps.
I had a similar error with my last project. Do you have a none displayed row selector? Please try to delete it to see if it will work.

Can a value list remember where you were last?

In my database, users are complaining that to input data in from a value list, even though they are inputting the same, or next, value in subsequent records they have to scroll down to where the last value was in the list.
Is there a method for filemaker to remember the last value chosen in a value list and display the drop down for the value list starting (in the middle) from there?
Sure, just set the field to the desired value before displaying the value list. Then it will start with that value selected.

Can I assign a value for one parameter

I am using crystal reports 2008. I want to generate a report for which i will get one value from one subreport and i want to pass this value as a parameter so that i can include this value in the sql command.
For eg.
From my subreport i will get customerkey and i want to pass this value in the sql as
{?customerkey}
Sql is 'select card_number from customers where customerkey={?customerkey}'
For this i created parameter in the command and added like this.
But what my problem is this customerkey is getting from subreport(using shared variable).If i get a value customer_key from subreport how will i assign this value to {?customerkey}. I tried like assighning this value but i dont want to popup {?customerkey}this value as a parameter.
Can anyone help? Please
So you want the data shown in the main report to be based on a parameter passed to it from a subreport? I don't think this is possible - the Report Processing Model (described here) states that SubReports are in 'Pass 2', while data retrieval is in 'Pass 1'. This means that the parameter prompt will always appear first.
You might instead be able to have the main report contain TWO subreports, the first of which is used to retrieve the parameter and the second uses it. That can get very messy, especially when dealing with page headers and footers.
