Reports were loading to PM Compass through Report Administration but would fail when run. This was a bug with the framework that was failing when a matrix-style report had a column group (left to right group) that contained more than one column group row.
As part of the pre-process for Deltek’s reporting framework, there was a walk through with the entire report, touching all textboxes to do things like adjusting formats for numbers and dates as well as applying other formatting. This is also done to support column selection for the standard reports. This was a case where the custom report layout was not being handled properly during the pre-process.
This was fixed on site and deployed to the development server. There were two fixes for this. One was to address the issue for a specific report, and the second change was a general change that generally skips the pre-process for a specific tablix. You can now set a custom property in the report designer for any tablix report control SkipProcessing and set it to Y. This allows you to bypass the framework for a given tablix report to essentially pass-through without changing the report at runtime. You will get what you see in the report designer. This was added in case another variation of a custom report is not being handled.
