I'm working on Business Central version 13.11 (13.0.35820.0) on-premise. Most of the code is C/SIDE but some is in extensions.
I need to make some changes to the Danish OIOUBL extension that exports an XML file.
Is it possible to get the code and make changes there or overwrite their extension with my own? (I need their code, because I only have a few things to change.)
I have read in a forum that two years ago it was not possible to subscribe to anything from their extension. So I don't expect that subscribing can help.
