Month Number to Month Name in Universe

Hi,

I have created a Universe based on BEx query in UDT.

We have a Fiscal Period object in query, which is giving period values in characters.

We want to convert those periods to Month names, I have used below syntax but giving me parsing error.

=if([0FISCPER3].[LEVEL01]=1;Jan;if([0FISCPER3].[LEVEL01]=2;Feb;if([0FISCPER3].[LEVEL01]=3;Mar;if([0FISCPER3].[LEVEL01]=4;Apr;if([0FISCPER3].[LEVEL01]=5;May;if([0FISCPER3].[LEVEL01]=6;June;if([0FISCPER3].[LEVEL01]=7;July;if([0FISCPER3].[LEVEL01]=8;Aug;if([0FISCPER3].[LEVEL01]=9;Sep;if([0FISCPER3].[LEVEL01]=10;Oct;if([0FISCPER3].[LEVEL01]=11;Nov;Dec)))))))))))

Please suggest me.
