Im using a ASP.NET based site with fairly complex SSRS reports embeded. i designed the reports in VS 08. My DEV, UAT, and PRD database servers that house my rdl files run SQL 08 R2. my DEV DB server is in the cloud while UAT and PRD are regular VM's.
the series of reports worked perfectly in the past in all environments but these problems may have began with a recent modification to allow users to expand/collapse all in data tables below graphs in each rdl.
columns of tables are hidden in these rld's based on input parameters and data passed to them from stored procedures.
the logic that works perfectly in DEV to present the appropriate table layouts but in UAT and PRD they do not. when loading a view that hides the first two columns of the data table UAT and PRD is also hiding the data returned for a third column.
Im looking here for input on why SSRS data table group and cell hidden expression logic would behave differently in different environments given that the rdl's, webpage files (aspx/cs) and stored procedures are identical.
