TIP: Working with changing Field DataTypes and Deleting fields in Business Central

Introduction:
Imagine a scenario where as per the requirements provided by your clients, you have set up the Database structure in NAV/Business Central.
Then comes a requirement in Phase 2 which completely redefines the database structure which was provided by you and you need to delete a few fields in a table and move it to another table.

Pre-requisites:
Microsoft Dynamics NAV
Microsoft Dynamics Business Central

Books & References:
https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/properties/devenv-obsoletestate-property

Solution:
1. In Microsoft Dynamics NAV, there was a flexibility to delete fields, tables, and keys and using  Force-Sync, you can directly delete the field, table, and keys from SQL Database.


2. Whereas in Microsoft Dynamics Business Central, you cannot delete the fields, keys, and tables.
In order to deploy this deleted change, you need to mention this field, table, and keys with Obsolete State Removed.


After you mention the field as Obsolete, in the page directly the field is


3. While deploying these changes in Business Central On-Premise, you can directly deploy the changes using Force-Sync through schemaUpdateMode property in AL.


Conclusion:
In order to delete a field the process has become relatively tedious in Business Central as compared to NAV. This is because from Business Central server point of view, the field is never actually deleted from the SQL Database it just gets disabled. Microsoft has made it easier for Business Central community by adding Force-Sync, other wise the developers will have to change the Application ID which in turn results in erasing of the data for the extension.
Hope you guys find this useful. 😇

I was wondering how to do this on a production environment in the cloud where ForceSync isn't possible.

I think Force-Sync works in Production as well.
You just need to upload the Extension App as you would and Business Central takes care of it.

In Order to change the data in the Table after changing the fields, you will need to write a code refer https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-extension-install-code
If Force-Sync does not work, a workaround would be creating a new field and marking the field to be changed as obsolete. And using OnInstallAppPerCompany() trigger you can migrate data from the old field to new field.

Creating APIs in Business Central - 1

Introduction:
While writing a blog on Automated Testing in Business Central, I was going through sample apps provided by Microsoft and realized that the complexity is nowhere close to what examples Microsoft has provided on docs.microsoft.com. In this blog, I will try to explain how APIs work and how to be creative with the implementation. Also, an API which were in beta are finally out with version V1.0 in the April 2019 release let's see some important key things from development aspects.
This blog is going to be theoretical one kindly bear with me.

How Business Central Modern Client Reverse Compatibility With NAV Can Help You Improve Your Work.

Introduction: Today, I was playing around with Business Central Modern Client (Windows App).
Out of curiosity I was trying to login to one of my NAV 2017 through SSO.
Pre-requisites: Microsoft Dynamics NAV with SSO configured
Microsoft Dynamics Business Central
Demonstration: 1. Business Central App - Main Page:

Clicking on locally hosted service and putting in the credentials configured for NAV 2017 SSO, we get.
Still skeptical when Business Central login into NAV.

2. Business Central App - Reverse compatible with NAV 2017:


Well well well...
Look whose here.
NAV disguised as  Dynamics 365 for Financials.

I think we all agree that Business Central Modern Client is a WebApp version of Busines Central Online. Basically just like browser in an App.
The difference is that it can connect to NAV as it is just like a browser.

3. Does Business Central Modern Client follow DynamicsNAV protocol?:
Well, it simply does not.
It would be amazing  if it did, as it would mean that we could deal with runni…

Generic way of Attaching Documents on any Record of the Page in Microsoft Dynamics Business Central - Template Code

Problem Statement: In Microsoft Business Central, there is a way to attach attachments only on Documents or Master Table records. But, what if this requirement is for other tables such as Opportunities, custom tables, etc. Introduction: I have seen many developers afraid to touch the attachment-related customization as it seems complicated.
Well, I have found a solution and here it goes.
In this blog, I'm attempting to create a generic template for code that needs to have an attachment feature on any table that you like using AL Code.
This means that you simply cannot copy-paste the same code for all the tables but a simple change in variable sub-type will ease your work significantly
