BO Rampup 4.0 WEBI strange error

Question

Dear All.
We are currently using BI 4.0 Rampup and trying to develop our application on it.
while creating an query when i add measure objects in the report it gives the Error "The DSL service return an error (WIS 00000)
if i remove the columns the report run without issue this error is not because of wrong defination of measure object in business layer because i check to change the measure objects and the error repeat with almost any combination of objects.
i have check the Query in Business Layer by adding all the measure objects and same filter and it runs without any issue, but in WEBI giving error.
if some body face this issue in WEBI 4.0 kindly please let me know.
In between i have checked when i remove some columns this error not came is this because of sub queries limitations, cause all the measures are restricted i.e. along with the where clause with diffrent parameters.
here is the complete exception.

Hi Syed,
I found the whole thing in WEBI for this BO4 is so unstable. Whenever you changed something of the underlying BEx Query and specially that involved Variable, the WEBI has always caused issues. You can't even determine what exactly caused the issue - and thanks to the Error message which is so unhelpful.
So far, from my own experience - anything to do with BEx Query that involves Structures and Variables (incl. User Exit Variable), you just have to be very careful with the impact to the WEBI reports.
I actually found the way to copy from W1 to W2 based on a copy from Q1 to Q2. You do this via "Change Source" in Design tab or Data tab. Once you copied the Webi, change the source query. So in this case, once you have W2 change the source from Q1 to Q2. Again, you have to be very careful with changes of the BEx query after you generate the WEBI report.
Cheers,
Andy
