Specifics of update_recordset crossCompany in AX 2012

Have you ever tried to run update_recordset crossCompany statement?
Yes, it is possible. There are only 5 methods in standard AX code with such statement, but it can be very useful for data update jobs in multi company environment.

Tables:
TaxTransGeneralJournalAccountEntry.moveTaxForeignKeyToTaxTrans()
RetailLoyaltyConflictCard.migrateConflictCards()

Classes:
ReqDemPlanForecastChangeTracker.applyAllChanges()
ReleaseUpdateDB63_HRMMinor.updatePositionForecastBudgetAcctLine()
ReleaseUpdateDB63_HRMMinor.updatePositionForecastCompGroupRefPoint()

You must disable update method, database log and alerts, otherwise compiler will throw an error, for example:

transTable.skipDataMethods(true); transTable.skipDatabaseLog(true); transTable.skipEvents(true); update_recordSet crossCompany transTable setting loyaltyCardId = conflictCard.NewCardNumber where transTable.loyaltyCardId == conflictCard.CardNumber && transTable.dataAreaId == conflictCard.Company;

If you are still not convinced, then there is another example below.
