"SV_STORE_NBR"']}, @{biServer.variables['NQ_SESSION.storenbr']}, @{biServer.variables['NQ_SESSION."storenbr"']}. I need it to be the values of TestVar1 and TestVar3, that were applied in a previous prompt as request variables, multiplied, but all I get is the original values from the session variables. You do not need to set up the PASSWORD variable, and you can use this variable in a database connection pool to allow passthrough login using the user ID and password of the user. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. There seems to be a glitch in the way obiee (11.1.1.6.0) interprets server variables when using them as default values for a dashboard prompt: only when the variable name is in uppercase and contains no underscores will it be recognised. Such directories begin with sk_. Required for authentication. Cache hits would only occur on cache entries that included and matched all security-sensitive variables.
