Workflows Error

Here is another article that talks about an error identified from the stack trace in Event Viewer. I have published a series of articles on Dynamics GP Workflows in recent times. After having installed Web Services, MOSS 2007 and Workflows successfully, I thought everything is perfect. I tried testing a dummy workflow for GL batch approval creating a one approver scenario. I was able to submit the batch for approval successfully. However, When i tried approving the said batch, it takes no action. To identify what’s happening in the back end, I opened Event Viewer. Remember that there would be a separate events series called Dynamics that would be available once you have workflows installed on the Web server running workflows. Under the Dynamics events, it was registering the following error every time I hit the Approval button.  

Action:

SubmitTaskAction

Current User LogOnName:

Domain\Admin

Input parameters:

Exception type:

System.ArgumentException

After a series of diagnosis on the error, I could finally resolve the same. The issue was with Service Accounts for MOSS as well as not importing the user profiles for Shared Services Provider (SSP). While configuring the MOSS, I used same account which is a farm administrator also for all service accounts. Certain Service accounts provide read-only access to the SharePoint databases. So, the account with which I’m trying to approve is being denied access due to the fact that the system is not able to identify this user as an administrator despite the fact that the said account is a workflows administrator in the web services security console as well. Adding to this, there is one step in MOSS configuration where we have to import all Active directory users into the shared services provider. I skipped this step too initially. After correcting these issues, the workflows started working absolutely perfect. So, We have to be 100% sure that we configure web services for Dynamics GP, MOSS correctly in order to ensure the workflows run successfully. Any small misconfiguration would lead to a failure of workflows.

Partner Point: A proactive approach MUST

Here we are talking about Dynamics GP in specific, but this is applicable to other products as well. Our job doesn’t end with just installing and deploying the solution out there. In fact, Our job as the most trusted partner would just start from there. We cannot expect the customers to constantly follow up on the latest software updates rolling down for their use because they expect they are in safe hands just like how You’d relax once you hand over your tax documents to your CPA. Microsoft on its part tries to send E-mail updates to the customers but how many of them would pay attention to these updates unless the partner approach them on a rather personalized basis explaining the benefits. I’ll illustrate the above with an example. We know Analytical Accounting has some critical updates pending in earlier versions of GP and these were made available in GP 10 SP4. As a partner, It becomes our obligation to take this update to the customers, whether they take your advice or not is d

Dynamics GP Fixed Assets GL Posting Batch Missing After Depreciation Run

I got a call from a user who was seemingly worried about her monthly depreciation batch went missing from GL posting routine in the Dynamics GP Fixed Assets. I quickly took her desktop on Teamviewer Quick support and understood the problem she is facing. Let me explain the issue in detail before I tell you the solution. Dynamics GP Fixed Assets GL Posting Issue Issue The user ran the depreciation routine in Dynamics GP for November month through Dynamics GP | Financial | Routines | Depreciate All Assets. Till here, all was good. She then proceeded to FA GL posting routine. Dynamics GP | Financial | Routines | GL Posting. She could not find the batch in GL posting lookup. In other words, the monthly depreciation batch is not accessible for posting. She then ran the depreciation process again and this time when she went to GL posting window and tried processing, the system threw an error message as below There are no transactions matching these restrictions.
