Dynamics 365 Blog - best_practice - Microsoft Dynamics 365 for Finance and Operations

I have had the problem in the past that the BP test did not find all expected deviations or even the following error was issued:

[BPFrameworkFatalException]:A fatal exception occured in the Best Practices framework.

In all these cases it has helped to disable the following rule: BPCheckTableDimensionFields

I found the decisive tip in the Dynamics 365 Community

In principle, every solution in Dynamics 365 for Finance and Operations should be free of best-practice deviations, but sometimes there is the need to suppress them.

Such a case are for example, event handlers that have a predefined parameter profile, but if one of these parameters is not used, it causes a BP deviation.

class MyFreeTextInvoiceHeaderFooterTmpEH
{
    [DataEventHandler(tableStr(FreeTextInvoiceHeaderFooterTmp), DataEventType::Inserting)]
    public static void FreeTextInvoiceHeaderFooterTmp_onInserting(Common sender, DataEventArgs e)
    {
        FreeTextInvoiceHeaderFooterTmp freeTextInvoiceHeaderFooterTmp;
    
        freeTextInvoiceHeaderFooterTmp = sender;
    
        if (freeTextInvoiceHeaderFooterTmp.CompanyBankAccount == "")
        {
            freeTextInvoiceHeaderFooterTmp.CompanyBankName = "Unknown";
        }
    }
}

With the above EH, the following BP deviation would be output because the parameter e is not used:

BP Rule: [BPParameterNotUsed]:The parameter 'e' is not used.

Usually the best practice checks are run during the build of a project/a solution. Sometimes, however, it can be quite practical to run them separately from a build.

Therefore Microsoft offers us the XppBp-Tool, see https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/dev-tools/author-best-practice-rules (at the bottom).

This tool is located in the PackagesLocalDirectory\bin directory and can be used as follows:

Xppbp.exe 
    -module:MyModel 
    -model:MyModel 
    -metadata:"C:\AOSService\PackagesLocalDirectory" 
    -all

A colleague of mine has brought to my attention the Dynamics Application Checker, which can be used to implement advanced best practice checks.

The used XQuery files can be downloaded from GitHub. How to use them I try to describe here.

1. Install BaseX (and Java if needed)
   https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/dev-tools/install-basex?tabs=admin
    
2. Download and extract files from GitHub
   https://github.com/microsoft/Dynamics365FO-AppChecker
   The files must be unpacked into the corresponding directory, e.g. C:\AOSService\PackagesLocalDirectory\Bin\AppCheckerRules
    
3. Build model
   In Visual Studio, under Dynamics 365 > Builds models, select the desired model and select the Run App Checks option:
    
4. Check result
   Now corresponding entries should appear in the ErrorList if BP deviations have been detected.
   
   
   In addition, a file AppCheckerResult.xml is stored in the packages directory, where the detected deviations can also be viewed.
