Debugging in Dynamics AX 2012 as a non-admin Role

To access breakpoints as a limited user:
1. open dynamics as admin
2. add yourself to your favorite role (in addition to admin)
3. shift control w to open a workspace.
4. insert a break point into a well know x++ class that the role accesses.
5. create a new job
6. insert this:
static void NonAdmin(Args _args)
{

securityutil::sysadminmode(false);
}
7. run job
8. control w to open regular workspace (or open it from the menus, sometimes its sticky)
9. Open the form/class via navigation

observe that you can now stop in debugger as "limited" user

• How can we create primary key for a table?
• what precautions you need for overriding fetch() method for a report?
• Difference between OCC and PCC?
• How many types of MAP there in Dynamics AX? 
• What is cache lookup what is it used for?
• Difference between table and views?
• why we use dialog? and how to accomplished it?
• what are the different type of index?
• Difference b/w cascade + restricted and restricted delete actions?
• In which case delete_from and delete() have same result?
• Explain sales/purchase order processes in AX.

Dynamics Ax 2009 Interview Questions – Part I

• Can you just tell the table properties that you can remember?
• What is cache lookup what is it used for?
• Different types of relation? Explain it detail?
• Explain OCC & PCC (optimistic concurrency control , Pessimistic concurrency control)
• Difference between views and tables
• Explain Queries? What’s it used for?
• Explain different types of reports?
• Differentiate auto design spec & Generated design? Which one is a preferable choice and why
• Primary Key in tables (In dynamics AX don’t have primary key)
• Explain primary index and Cluster index? Explain in detail?
• What is the default index for a table?
• Explain delete action? Types of delete action?
• What are all the add- on tools you used in Dynamics AX (It’s an indirect question for AIF)
• Did you work with EP (Enterprise Portal & Workflow) how can you implement this features into your projects
• Can you just point out some best practice you used when u develop a project?
• Did you worked with base modules?  Actually I answered this question as  
• I worked with production module to integrate with our steel process management
• So can you just point out three classes that you used in production module
• Explain the posting in production module
• When you create production order….Can you point out the affecting classes, tables.

Dynamics AX2009 Workflow – Checklist

I was going through the the workflow implementation with a client and could notice that there is a need of a check list for consultants users to configure the workflow and make it work . I have thought of the following points for the check list.
1. User options

a. Maintain the email address of the users .

b. Setup The parameters for receiving the notifications on the Notifications tab especially the two marked parameters for getting the notifications in client and or email.
 

2. Administration>Setup>Email parameters must be setup so that emails can be sent through AX.

3. Basic>Setup>Setting for workflow>settings for workflow to be used by the system to send workflow emails.

4. Configuration of the email template as identified in step 3 above. Basic>Setup>Email templates. FOr setting templates refer to the AX help file. Its a good source of information.

5.  Ensure that the batches to process the alerts and the email messages are active.
      a. Email batches – Administration>Periodic>Email processing> Batch.
         

     b. Alert batches – Basic>Periodic>Alerts
        
6. Workflow configuration is configured properly . There should one default configuration . Additional configurations may be maintained with specific conditions for becoming active.

e.g. workflow on purchase requisition may have following setup
  
One active version per configuration must be maintained.

7. Workflow rules should be defined properly. If the tasks are being assigned on hierarchy basis then there must be a stop condition maintained ( This is the general error that users do not maintained a stop condition.)

8. Setup events when to generate a notification in an approval process.


I think if above check list is cross checked during setup or troubleshooting most of the errors / problems would be solved related to workflow . For rest of the problems leave them for consultants/developers to investigate on case to case basis.
