Extensions between versions (2016/2017)

Tranad

Hey there !

I was testing extensions in the Nav 2016 (Cronus Database) and couldn't achieve what I wanted to do. So I decided to download Nav 2017 (Downloadable here if you fill a little survey). Then I thought "Nice ! I will be able to install my 2016 extension on 2017 !".

I got an error :


This wasn't a big extension, but I had to add a field in "Sales Header" Table in it. Understanding how the .DELTA files were generated (here you have a pretty good example, made by Ashwini Tripathi) I decided to check the differences between "Sales Header" 's table in those versions, using WinMerge :


(Just in case, all the yellow/grey zones are added/missing code lines)

I got sad, this was blinking more than my Christmas Tree ! When Microsoft announced this new feature, I directly thought about the migrations, like right click, copy, right click, paste.

Can I only use my extensions in the Navision version I developped it ?

Many thanks in advance,

Do you have any other extensions already published in db?
please check whether any previous extension used field id's or new object id's which are used in present extensions.

we need to have a extension upgrade functions along with each extension
so create global upgrade functions (atleast blank) OnNavAppUpgradePerDatabase and OnNavAppUpgradePerCompany

Thanks for your answer.

I've made some research on those two functions, and tried to follow Waldo's topic (It seems like the function "RESTOREARCHIVEDATA" is only available in NAV 2017). I didn't understood well where I had to use those functions, but I presume in the 2016, in a new CU included in the package.

I tried, creating a new CU in NAV 2016 with those two empty functions :


Then tried to install the new package which included the CU newly created, and had this error :


Could you enlighten me about this new error please ? This all being new, I can't find any hint on the net.
