Handling Characters Like # in Data, when exposing HANA views via oData services?

Question

We've some special characters in the fields (like '#' ), and because of this the client side ODataModel /JSON parsing is breaking when ever the data has these characters.
Is there anyway to encode this at the HANA server level while exposing the views?

Hi Latha,
I've tried numerous combinations but I can't seem to create a view to return the data that I need.
For example, I thought I would need to create an Attribute view based on the M_TIME_DIMENSION_WEEK table BUT then noticed that I can't join this to my table as I only have a date column, i.e. at DAY granularity.
Therefore I created an attribute view based on the M_TIME_DIMENSION table to match the  granularity of the Date column in my table and joined this to my foundation table using the SAPDATE column..
The M_TIME_DIMENSION table also has a WEEK column and I thought I would be able to use that as a basis for the aggregation (SUM) of my Amount column but I haven't been able to make that work.
So basically I have a table like this:
MANDT
NVARCHAR
COMPANYCODE
NVARCHAR
BUSINESSPARTNER
NVARCHAR
AMOUNT
DECIMAL
CURRENCY
NVARCHAR
POSTINGDATE
NVARCHAR
And I want to return sums of the amount field based on the WEEK number of the POSTINGDATE field
The annoying thing is that I can write a simple SQL statement like this to produce what I want:
select  week(postingdate), sum(amount)
from myDbTable
where year(postingdate) = 2014
and companycode = '123'
and currency = 'EUR'
and mandt = '090'
group by week(postingdate)
The problem is reproducing the 'week' function in an analytic/calculation/attribute view.
Of course 'companycode', 'currency' etc would need to be dimensions but I'm sure you understand what I mean.
Any tips/ideas would be very welcome.
Kind regards,
Keith
