Error "Line too long" - Report too large?

I'm working with a report which is being generated dynamically through
an XML and XSLT transform which generates the .rdl file which is then
pasted in to the code view of a report file in Visual Studio. This
process has worked so far for various reports until we came to this
latest report.
This report is a bit larger in scale, all together the final file size
of the .rdl file is just about 2MB. Of course it's a bit slow to work
with in Visual Studio, but the goal again was to generate the .rdl
dynamically so that editing the file(s) in Visual Studio would not be
necessary.
The report loads fine into Visual Studio and the layout view of the
report looks fine as well, but when we attempt to preview the report,
we get a build error which states:
[rsUnexpectedCompilerError] An unexpected error occurred while
compiling expressions. Native compiler return value: '[BC30494] Line
is too long.'.
I've attempted to locate information on the error message or the error
code itself but can't find any references anywhere. The error is
occurring on compilation of the report - because the same error occurs
when we select 'Build' from the context menu of the report.
So since it's a compilation error and the message seems to indicate
that the error occured while compiling expressions (and expressions use
VB.NET syntax) my assumption is that the source of the report is
somehow being passed in as a parameter to a version of the VB.NET
compiler and then spit back out for further processing.
If you follow that logic, my first thought was that perhaps one of the
expressions was literally too long and perhaps needed to be broken up
into smaller lines. But this was not the case. As the longest 'line' in
the report is 384 characters. Not long enough to cause any problems.
And we have other reports with lines just as long which do compile.
My next thought was that the entire source of the .rdl file was being
passed in to the compiler as a single string for parsing and execution
(e.g. turning the expressions into actual values or something similar).
If this is the case, then perhaps it's the actual size (in characters
or bytes) of the .rdl file that was the problem.
That's currently where I am now. I've narrowed it down to a theoretical
file size limit.
While trimming the report down piece by piece, I've discovered that the
same report works when it is in the area of 1.63 MB in size. However,
as soon as the report reaches 1.79 MB in size, this error returns and
the report fails to build.
I've seen other posts and documentation regarding the theoretical or
imposed limits of IIS and other platforms for uploading reports to
report server, but we are still below the 4MB limit.
I've also seen other posts by users who have asked about reports in the
range of <1MB, but ours is clearly outside that range.
So, does anyone have any information related to this error message, any
limits on .rdl file size, or suggestions for getting this to work?In case anyone is interested about this later on, I haven't found a
solution to the problem yet, but have found a workaround.
I was able to break the report up into smaller, more manageable chunks
(each one around 1MB in size) and create a master report and include
each chunk in a subreport.
So that's how I'm dealing with the problem for now, but I'm still
wondering if the errors I've encountered are really related to the size
of the report or something else.|||will.s.smith@.gmail.com wrote:

Hi,
Iam have a RDL file where the file size is over 4MB
I have been workiing with it and deploying various versions of this
file size for the past couple of weeks ,without any errors and now
unexpectedly when iam to go live tomm Iam getting this error ,
I really don;t have any clue on how to handle this
Any help would really be appreciated
this is the compiler error iam having
[rsUnexpectedCompilerError] An unexpected error occurred while
compiling expressions. Native compiler return value: '[BC30494] Line
is too long.'.
Basically iam having 24 table data regions each pulling data from the
same dataset with different filtering options
only when i add the last 4 table regions iam gettign this error
Keep in mind that i was not getting this error last week with the same
24 data regions
