М... похоже, что можно В \Classes\SysCompileIL\generateIncrementalIL есть такой код:

// Dump incremental xml files
changeFound = !dumpChanges || SysCompileIL::dumpIncrementalBulk();
if(changeFound)
{
    AppVersionStr = ApplicationVersion::applBuildNo();
    AppVersion = new System.Version(AppVersionStr);

    xppILAppDomain = xApplication::XppILAppDomain();

    parameters = new Microsoft.Dynamics.Ax.Xpp.GeneratorParameters();
    parameters.set_AppVersion(AppVersion);
    parameters.set_AssemblyName(#XppDllName);
    parameters.set_EnableDebugging(true);
    parameters.set_EnumFile(xmlPath + '\\Enums.exml');
    parameters.set_NumberOfModules(#NumberOfModules);
    parameters.set_WritePath(writePath);
    parameters.set_XmlPath(xmlPath);
    parameters.set_OldAssemblyName(xppAssemblyPath);
    parameters.set_GeneratorAppDomain(xppILAppDomain);
    parameters.set_IsDebug(Debug::isDebugOnAOSEnabled());
    parameters.set_LogFolderPath(writePath);

    modifiedModules = Microsoft.Dynamics.Ax.Xpp.XppILGenerator::GenerateIncrementalAssembly(parameters);

Здесь видно, как собственно запускается инкрементная компиляция. А вот в вызываемом методе SysCompileIL::dumpIncrementalBulk() есть такие интересные строчки:

SysModelElement sysModelElementChildren, sysModelElementSameBucket;
SysModelElementData sysModelElementData;
SysCompileILTable sysCompileILTable, sysCompileILTableSelfJoin;

// insert any type that has changed.
insert_recordset sysCompileILTableSelfJoin(Name, ModelElement, ElementType, AxId, GenerateType)
select Name, RecId, ElementType, AxId, generateType from sysModelElementSameBucket
exists join sysModelElementChildren where sysModelElementChildren.ParentModelElement == sysModelElementSameBucket.RecId
    && (sysModelElementChildren.ElementType == UtilElementType::ClassInstanceMethod
    || sysModelElementChildren.ElementType == UtilElementType::ClassStaticMethod
    || sysModelElementChildren.ElementType == UtilElementType::TableInstanceMethod
    || sysModelElementChildren.ElementType == UtilElementType::TableStaticMethod
    || sysModelElementChildren.ElementType == UtilElementType::TableRelation
    || sysModelElementChildren.ElementType == UtilElementType::TableField)
exists join sysModelElementData where sysModelElementData.ModelElement == sysModelElementChildren.RecId && sysModelElementData.ModifiedDateTime >= modifiedDateTime;

// Insert types in same bucket as types that changed
update_recordset sysCompileILTableSelfJoin setting NetModuleId = (sysCompileILTableSelfJoin.AxId / #GroupSize) mod #NumberOfModules;
insert_recordset sysCompileILTable(Name, ModelElement, ElementType, AxId, GenerateType)
select Name, RecId, ElementType, AxId, generateType from sysModelElementSameBucket
where sysModelElementSameBucket.ElementType == UtilElementType::Class || sysModelElementSameBucket.ElementType == UtilElementType::Table
exists join sysCompileILTableSelfJoin where sysCompileILTableSelfJoin.NetModuleId == (sysModelElementSameBucket.AxId / #GroupSize) mod #NumberOfModules;

Самое интересное тут - установка поля SysCompileILTable.NetModuleId:

update_recordset sysCompileILTableSelfJoin setting NetModuleId = (sysCompileILTableSelfJoin.AxId / #GroupSize) mod #NumberOfModules;

Используемые при его вычислении макросы #GroupSize и #NumberOfModules определены в \Macros\XppIL:

#define.NumberOfModules(1000)
#define.GroupSize(10)
