I am using Tableau Prep to load PDFs to SQL server. The PDF contains several tables. All the columns except the one with NULL values is not created. If there are 12 columns in the PDF, I'm seeing only 11 in the Output. There's a column that has NULL values. Is there a way to create a column to have NULL values? The column is blank initially(eg, Jan, and values are being populated from Feb onwards) and then is being populated with float values. The PDF's need to be loaded daily. I created the column but it gives an error 'Error adding Text[columnname]. Expected different text.' Prep Version is 20.3.3.
Do I continue loading the Jan files and then is it possible to add the column and map it Feb onwards?
Is there another way to accomplish this?
Thank you in advance.
A little late answering but, you can add a null column as follows:
After connecting to your pdf table, add a Clean activity
Select data grid view and right click on a column
Select Create Calculated Field then Custom Calculation
Name your calculation and set the calculation value as NULL
Reset the data type as Number (decimal)
Add an output activity, saving output to Database table

I am trying to convert some measures that I have into dates for making a line chart. This is the data I have.
[
I am trying to make a line chart out of this data. But I cannot put it under a date since there are no dates in the dimensions. Any help would be appreciated.
You will need to some how reshape this data to create a single date field. You can do that out of Tableau or perhaps use Tableau prep. Your underlying data source is likely to drive that decision, you don't mention anything about that in your question.
Edit from comments:
Connect to the spreadsheet in Tableau. In the Data Source window, where it shows you all of the data in a table, select the 4 fields starting with Tuition and Fees. Then click on the drop down and Pivot those fields.
That will create 2 new fields, Pivot Field Names and Pivot Field Values.
In your workbook create 2 new calculated fields:
[FeeYear]: LEFT(RIGHT([Pivot Field Names],7),4)
and
[FeeDate]: MAKEDATE(INT([FeeYear]),1,1)
You can use FeeDate as the x axis of your line chart. Pivot Field Values is the measure to use in your line chart.
I'm trying to find a way to create a table like the one above, but instead of having columns of months I would like to have columns of MTD, QTD, YTD for all selected measure values. I created calculated fields on the [Date] field but when I try to use that it still splits the data in to separate columns of months and quarters... I'm using two data sources and they are linked on the [Date] field. If I try to put two of my calculated fields in the columns bar it just combines them like 'MTD/YTD'. How can I get them to display as separate columns?
I know this is strange because there will be overlapping data (everything in the MTD will also be in the QTD and the YTD).
I found a way to do this. I created a calculated field on the date field and assigned 'MTD' to all records from the last month. Then I assigned 'QTD' to all records from the start of the quarter to the day before the start date of the 'MTD' records. Then I assigned 'YTD' to all records from the start of the year to the day before the start of the 'QTD' records. (this way there are no overlapping records).
After that I just did a quick table calc to make each of them a 'running total' table (across).
I created parameters for the dates so the can easily be updated.
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.
I created a report where I want to show the heading of a column based on a parameter. I tried using both table and matrix format, but I'm unable to reduce year.
year=2013
For example if I choose 2013 in the report this means it will show the last 10 years in the repor, i.e. 2013,2012,2011,2010,2009,2008, up until 2002.
If I understand your question correctly you want to query a database and display the results in a table with a column per year. You can do this by using by using a Matrix object and Column Groups
Add your Matrix object by drag and dropping. Select the Column Group | Group Properties and add a Group Expression.
Use the following code as your Group Expression.
=Year(Fields!Date.Value)
Two fold I'd think:
Alter your sql to accept the parameter and get the bast 10 years in column names 1, 2, etc.
Then use an expression in the header or title similar to =#Parameter!par.Value - Cdec(Data!1.Value) to show headers for 2013 to 2002.
I hope I was clear?
