Preventing Visual Studio Tools customization processes from being terminated by Microsoft Dynamics GP

Just recently I ran into a case on the Microsoft Dynamics GP partner forum where the ISV developer was dealing with a potentially long standing process to be executed from within their Visual Studio Tools (VST) add-in customization. As a result of this long standing process, the developer wanted to prevent Microsoft Dynamics GP from closing while his process was executing.

The Theory Part

Typically, while a process is executing in Microsoft Dynamics GP a user attempting to close the application would receive the following message:

Process are being run message

However, Microsoft Dynamics GP can cause a Visual Studio Tools customization to abruptly shut-down if a user closes the application deliberately or accidentally. Microsoft Dexterity developers have never had to worry about this since Dexterity processes are managed by the call stack.

A call stack is an internal Dexterity mechanism that manages the processing of scripts. Dexterity has eight call stacks; seven are used for foreground processing while the other is used for background processing. When the scripts on a particular call stack have finished processing, the call stack is available to be used again. Scripts in the call stack can be viewed in Process Monitor whether they are foreground, background, or remote processes.

Process(es) in call stack while running a Trial Balance report

In some instances and depending on the type of process, a Dexterity developer have the ability to mark such a process as removable from the call stack, in which case the end-user can take advantage of the Process Monitor window to delete the process from the call stack.

The Solution

In order for a Visual Studio Tools add-in to protect itself from termination by the Microsoft Dynamics GP application while processes are being executed, you can add the following lines of code before and after the process to be executed.

C# Implementation 
//tell Dexterity's runtime engine that we are running background.

Microsoft.Dexterity.Shell.DexGlobals.BackgroundProcessesPending++;    
// Execute your process(es) here
//
//
// tell Dexterity runtime engine we're done
Microsoft.Dexterity.Shell.DexGlobals.BackgroundProcessesPending--;

Hopefully you have found this article useful.

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

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

Moving on from my previous article on a similar subject - see Cannot insert the value NULL into column 'BASEUOFM' error when clicking on Items List in Navigation Pane , I recently came across this error,  Cannot insert the value NULL into column 'CONTACT' when clicking on the All Purchasing Transactions list under the Purchasing Navigation Pane option, after performing an upgrade from Microsoft Dynamics GP 9.0 to Microsoft Dynamics GP 2010 R2. All Purchasing Transactions list error - Purchasing Navigation List The name of the global temp table - in this case, tempdb.dbo.##2093338- varies in almost all cases, but the end result of the error is the same. The issue has been identified running Microsoft Dynamics GP 2010 RTM, SP1 or SP2. Upon further review, the issue is due to bad data in the Vendor ID (VENDORID) column in the Purchasing Receipt History table (POP30300). In summary, if you have a purchasing receipt with a blank vendor ID or a vendor ID that doe
