During my AX 2012 R3 RTM installation, I found some warnings left after do 'Generate full CIL'.
Path
\Classes\PayrollCalculatePayStatementBenefits\retrieveSymmetryBenefitLimits
Error message
CIL generation: Severe Warning: .NET type Symmetry.TaxEngine.BenefitType is not found during IL generation. 'PayrollCalculatePayStatementBenefits.retrieveSymmetryBenefitLimits' will throw an exception at run time.
Analysis
First of all, it seems to be that you can ignore this kind of warning if you're not interested to use US Tax payroll function.
However if you would like to clean up all of above warning. The possible ways are:
Option A - Install related components or libraries US Tax payroll functions needed. However at the moment I don't have details about this. ; ) (Would be good if someone can help to clarify as well)
Option B - And this is my choice. Just omit it! Because of my current tasks not related to that tax feature, so disabling the function is fit to me.
Solution (as skip)
1) Deselect the US payroll function
2) After that, do generate full CIL again. The warnings would be disappeared.
Until the next post!
