Calculated attribute: Concatenated String not possible ?

Hi,

whats the syntax to make a concatenated String view in a calculated attribute of an analytical view ?

For Example in metasyntax:

<CONST> = 'EDF'

CHANNEL_DESCRIPTION = 'Internet'

<CONST> || CHANNEL_DESCRIPTION = 'EDF Internet'

Is this possible ?

How ?

ThanXs
