How to check/add Cust/Vend Journal transactions to Sales Tax (Italy) report

In AX2012 and D365 there is a specific Italian report "Sales Tax (Italy) report" named "Libro IVA", it contain all transactions about VAT/Sales tax.

By my point of view, an helpful checkpoint, is to veify for each Sales Tax transactions the Posting-parameters.
I'm meaning: Purchase->Invoice Journals; Sales ledger-> Payment Journal and others.
In case we are facing to some transations missing in SalesTax (Italy) Report, the first check is to verify these TaxTrans data:

mandatory fields

The fields are: TaxTrans. TaxBook and TaxTrans.TaxBookSection.
These fields create the link between transactions and Tax Report.

table fields

AX 2012 - Fixed default dimension

 Con questo job possiamo ottenere i valori "fixed" sulla default dimension di un conto:

 static void GetFixedDefaultDimension(Args _args)  
 {  
   Map           map;  
   MainAccountLegalEntity MainAccountLegalEntity;  
   MainAccount       mainAccount;  
   MapEnumerator      enumerator;  
   DimensionStorageSegment DimensionStorageSegment;  
   DimensionAttribute   DimensionAttribute;  
   CompanyInfo       companyInfo;  
     
   companyInfo = CompanyInfo::find();  
     
   select firstOnly MainAccountLegalEntity  
     join mainAccount  
     where mainAccount.RecId == MainAccountLegalEntity.MainAccount  
     && mainAccount.MainAccountId == "200100"  
     && MainAccountLegalEntity.LegalEntity == companyInfo.RecId;  
     
   map = DimensionDefaultingService::getFixedDimensionsForMainAccount(MainAccountLegalEntity.MainAccount,MainAccountLegalEntity.LegalEntity);  
     
   enumerator = Map.getEnumerator();  
     
   while (enumerator.moveNext())  
   {  
     DimensionStorageSegment = enumerator.currentValue();    
     DimensionAttribute = DimensionAttribute::find(enumerator.currentKey());  
       
     info(strFmt("%1:%2 -- %3",DimensionAttribute.Name  
                  ,DimensionStorageSegment.parmDisplayValue()  
                  ,DimensionStorageSegment.getName()));  
   }  
 }
