Hybrid development for the Managed Code developer (cont.)

In my previous article I outlined a hybrid development approach for managed code developers that allows for a C# or VB.NET programmer to make use of Modifier and Dexterity as complements to deliver a solution - see Hybrid development for the Managed Code developer.

In summary, a managed code developer could leverage Modifier to effect changes on the core Microsoft Dynamics GP (or any add-on or third party product) user interface, then use Dexterity to create the table definitions and routines that will make those tables available on SQL Server - the added advantage? tables are exposed to Microsoft Dynamics GP security model and are created on the first launch of your dictionary and you can create an assembly for the dictionary to drive table operations from your Visual Studio Tools solution that will not require the use of ADO.NET or even the GPConnNet.DLL file to access the tables. Finally, your Visual Studio Tools code would be used to drive the user interface controls added with Modifier and the table operations (the glue to it all if you will).

In using this hybrid approach, there are a number of considerations for deployment:

The Modifier bit
To deliver the UI changes to your customer, you will need to export a package file - using the Customization Maintenance window - that contains only the modified resource. Since it's possible to have VBA code with your UI changes, you may also need to export any references.

As best practice, export any references as a separate package as they may already be loaded in your customer's environment.

Since you also had to create an assembly for the modified forms dictionary (FORMS.DIC) using the Dictionary Assembly Generator tool (DAG), you need to include the Applications.Dynamics.ModifiedForms.DLL file with your package.

Note: as a best practice, you should generate a modified forms assembly using the actual forms dictionary from your client's environment, plus your UI changes. This will prevent any incompatibility with existing forms customizations when deploying the assembly in their environment. On the flip side, some developers prefer to DAG the clients FORMS.DIC dictionary file on site after the package file has been imported. This may still require to change the references within your existing Visual Studio project to use the modified forms assembly and recompile to create your final DLL.

Deliverable work products from this section:
  • Package File with UI customizations
  • Applications.Dynamics.ModifiedForms.DLL
The Dexterity bit
Since you created a Dexterity dictionary to deliver the table implementation (and any other bit you may have needed to facilitate your development project) you will now have to follow the conventional chunking process for your Dexterity application, YourPROD.CNK.

In addition, you would have needed to create an assembly for your Dexterity dictionary to reference in your Visual Studio Tools project using the DAG utility, yourCompany.YourProduct.DLL.

Deliverable work products from this section:
  • Chunk dictionary file with table creation/upgrade routines
  • yourCompany.YourProduct.DLL assembly file
The Visual Studio bit
As you are familiar with this process, suffice to say your actual VST project that serves as glue to the UI and table operations will need to be compiled into an assembly that will be deployed with the rest of components.

Deliverable work products from this section:


  • yourCompany.YourProduct.Extended.DLL assembly file
So in summary, you will be delivering 5 components with your application. While this may sound like a lot, it makes for a really slick solution. I want to hear from you about hybrid solutions you have created and how you have leveraged each tool.

DBMS: 12 Microsoft Dynamics GP: 0 error when updating to Microsoft Dynamics GP 2013 R2

Image
Hello all! It's been quite a while since I've actually written anything of remote interest to anyone who follows my blog, but at the same time, you will be pleased to know that I've been quite busy in the consulting front, with upgrades, server migrations, complex multi-instance postings involving 10's of thousands of transactions, wrapping up some Field Service Automation projects, and the list goes on and on. This time around I want to bring to the forefront, an issue I encountered updating  from Microsoft Dynamics GP 2013 SP2 to Microsoft Dynamics GP 2013 R2 plus the latest service pack. Background My client requested a server migration to a new environment where they wanted to deploy Dynamics GP 2013 R2 web client (plus the latest service pack) and upgrade their relational database management system to Microsoft SQL Server 2014. This is something I'm absolutely comfortable with (for the most part) given also that my client was sitting at Microsoft Dynamics...

Do I have to use those "Z-" currency IDs in GP?

Image
I know this seems like a trivia question, but recently I have come across a number of clients who have been using Microsoft Dynamics GP for a number of years and have been told by their former partners that they *must* use the predefined currency IDs created after adding the sample company, with no real explanation to support these claims. Case in point, my new client in Saudi Arabia, has been struggling for years to understand why they were told to prefix all currency IDs with the "Z-". So they went ahead and setup "Z-SR" for the Saudi Real. If you are familiar with Microsoft Dynamics GP and the sample company, Fabrikam, you may have noticed by now that after adding the sample company (which is not a requirement by any means), you will get a number of predefined currencies such as Z-US$ (US Dollars), Z-UK (British Pounds), Z-C$ (Canadian Dollars), Z-AUD (Australian Dollars), and so forth, accompanied by a number of exchange rate tables. If you are not familiar wi...

Microsoft Dynamics GP Scrolling Windows and Line Sequence Numbers

Image
I thought I would write about something meaningless that no one really thinks about. However, I realized that this is a compelling topic since it makes for some interesting discussion around the ability to insert line items withinin most transaction scrolling windows. Let’s take some time to understand where Line Sequence Numbers come from. A Line Sequence Number is auto generated by Dynamics GP and uses a seed value of 16,384 as a basis for the first line. Each subsequent line in the scrolling window is incremented by this number, so line number 2 would have a Line Sequence Number value of 32,768, line number 3 would have Line Sequence Number Value of 49,152, and so on. Since most GP transaction entry scrolling windows allow inserting rows in between line items, the newly inserted Line Sequence Number value is calculated as an average between the previous and the next line item sequences, i.e., if you were to insert an item in between row 1 and row 2 in the scrolling window -- keep in...
