D365 BC - Codeunit 1

Dean_Axon

Hi all,

in this version CU1 has gone. Does anyone know where the functions have moved to ? I'm interested in finding the new home for ApplicationVersion().

Thanks in Advance

Have you seen any guidance on how to use these , I have found nothing so far ? Is there new system event for ApplicationVersion() ?

Hi, in the official Microsoft Doc. there is a section about replacement of codeunit 1 as per the following link ; https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/upgrade/codeunit1-replacement

During an upgrade, is this replacement only required when custom logic was included in Codeunit 1 in the old database? i.e. if upgrading from 2017 to BC on Prem. and no custom logic was included in CU1 of 2017, do we still need to include to the replacement CU provided by microsoft?
