What do you mean by displaying null?
Is it displaying "NULL" or "null"? If so there is some code to do that.
As my knowledge, in general BI Publisher won't replace null with "NULL" or "null". Some one has written some code in rtf. Cross check for that.

I copied the below text from the User Guide:

Quote:

• To define behavior when the element is present and the value is not null, use the following:
<?if:element_name!=?> desired behavior when the element exists and is not null <?end if?>
• To define behavior when the element is present, but is null, use the following:
<?if:element_name and element_name="?> desired behavior when the element exists but value is null <?end if?>
• To define behavior when the element is not present, use the following:
<?if:not(element_name)?> desired behavior when the element is not present <?end if?>

How does this look like (screenshot, possibly)?

A DATE column can contain dates (such as 03.11.2008 (dd.mm.yyyy)) or it can be empty so its value is NULL. A DATE column's value can not be a blank space as it is a character string.

Basically, if you select NULL from a table, it is displayed as NULL (on a paper, it looks as if it was invisible).

Now, I don't use BI Publisher so this might be a tricky question which requires some settings to be done, but - theoretically speaking, NULLS are simply NULLS. You don't have to do anything about them /forum/fa/3314/0/

@littlefoot

i do not know how to attach screen shot. I just tried using ctrl+PrtSc and saved it in word file. I am attaching the word file wherein the first row has value as null against date column

i could not attach word doc hence using paint i created as gif and attaching screen shot. thanks i have learnt new thing too
@vamsi

yes it is a problem with rtf creation. but still when i attach this file to my apex page and when i am opening report through word document i am getting the values "null" against date column.
As you have suggested i will try to use <if endif > but the problem where to place? i will try to locate

thanks
