Hi,

In the crosstab report I am using one of the expression as

if([Type]= 'M') then('Mag zines.') else('book')

so it shows the count of each for a store.. But if that store does not have magzines  for a time period(like Quarter)  then it should display '0' but it is not pulling that column at all.

It is just  pulling book and displaying its numbers.

It could be because of null suppression that is automatic in crosstab.
Change expression of your measure to coalesce () or nullif or (if null then 0 else measure) etc... expression.
Use the one that works according to your database.

the [Type] data item I am using above is text  so when I am using coalesce () it errors out.

If possible can you please let me know how to use nullif and others with an example of condition/expression

then use a if else statement to check for null and if null put '0' value.
