Increase the size of ProjId in Ax2012

Hi,

I have Increased the size of ProjId to 40 characters in Ax2012 , but when tried to sync the data dictionary two errors were thrown because it's used in two views (BankLGDocumentView,smmActivityAssociationView) with join type"union" with DocumentId which means I have to Increase the size for purchId, SalesId and many other data types, can you please let me know if there is another way to Increase the size of ProjId in Ax2012?

Thanks.
