"The DefaultValue expression for the report parameter ‘AX_CompanyName’ contains an error: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. (rsRuntimeErrorInExpression)"
The resolution we found was to use "FullTrust" permission set in place of "Execute" for the "Report_Expressions_Default_Permissions" in the rssrvpolicy.config but maybe there is some other solution that I was not aware of.
Existing configuration:
<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="Execution"
Name="Report_Expressions_Default_Permissions"
Description="This code group grants default permissions for code in report expressions and Code element. ">
[...]
</CodeGroup>
Replacement configuration:
<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust"
Name="Report_Expressions_Default_Permissions"
Description="This code group grants default permissions for code in report expressions and Code element. ">
[..]
</CodeGroup>
