XFBR in Literal Parameter is not returning value as expected

[VENKAB05]

Hello Everyone,

I need a Literal parameter which will dynamically calculate something like the prior forecast based on another parameter so i ended up writing an XFBR for that Literal parameter, something like below

XFBR(HelperRule,GetPriorForecast).

And now i need this Prior Forecast value for some Finance calculations. So I tried to retrieve the value of Parameter in the finance rule by using 

BRApi.Dashboards.Parameters.GetLiteralParameterValue

But it returns the same "XFBR (Helper Rule, Get Prior Forecast)" rather than the Actual String Value.

Strangely enough, if i use the same XFBR for Scenario Filter in a DM step, it picks up the proper string value.

Curious Why would it not work when I try to retrieve its value in a finance BR?

Isn't this the expected behaviour? You are essentially trying to call or trigger an xfbr function inside a business rule. Whereas it correctly invokes the XFBR before running any action like a DM step.

You could perhaps directly call that function by using the referenced assembly.

Thanks sudarshan,

I was under the impression that i was doing something different and wanted to clarify.

You can call the XFBR directly from the rule where you need the Prior Forecast value.  The Literal Parameter step is an extra, unnecessary step.
