Problem Statement
The problem reported consist on not been able to open and use the plots in What-If Simulation, returning the following error:

<html><body><div id="body_msglog"><font face=Verdana size=4>Error 2</font></div></body></html>

Solution
This issue is caused by the number of future moves and the magnitude of some of the dependent variables. This is exceeding a 600 character limitation in the query. The workaround is to truncate the prediction array to some smaller number of points to allow the vector to fit within the 600 character limit. The attached field test will do this.

To install the field test follow the next instructions:

1. Download the attached file
(WhatIfSimulationPlotFix_v11_v12.rld) to the aspen watch server.

2. Run InfoPlus.21 Manager and choose the View -> Utilities menu option.

3. On the Records tab, choose Load and "Use first free record id".

4. Click Browse and select the rld file.

5. Click Execute.
