Set up a new number sequence (e.g. for Blanket Orders)

1. New Data Type
   
2. Add a new SalesParameters method:

   static client server NumberSequenceReference  numRefSalesIdBlanket()
   {
       return NumberSeqReference::findReference(typeId2ExtendedTypeId(typeid(SalesIdBlanket)));
   }
   

3. Assign SalesId in the somewhere during the creation of the blanket order:

   salesTable.SalesId = NumberSeq::newGetNum(SalesParameters::numRefSalesIdBlanket()).num();
   

4. Add new reference to NumberSeqReference_SalesOrder class (used to add the new number sequence to the list in the CustParameters form)

   protected void loadModule()
   {
       NumberSequenceReference numRef;
       ;
   //blanket order number sequence
       numRef.DataTypeId              = typeId2ExtendedTypeId(typeid(SalesIdBlanket));
       numRef.ReferenceHelp           = literalstr("@SYS53960");
       numRef.ReferenceLabel          = literalstr("@CUS525");
       numRef.WizardManual            = NoYes::No;
       numRef.WizardAllowChangeDown   = NoYes::No;
       numRef.WizardAllowChangeUp     = NoYes::No;
       numRef.SortField               = 1;
       this.create(numRef);
       …
   }

5. Set up the new number sequence in the customer parameters form.

Done.
