Workflows vs Plugins in MS CRM

What is the Issue?

When to use workflows and when plugin? What is the difference in these two?

What is Confusion –

Many of the developers or MS CRM beginners get confused in some scenarios whether to go with Workflows or to go with Plugins, as both can be used and has ability to perform specific task at server side.

Solution –

Plugins and workflows have some specific and significant differences-

1. Workflow has specific set of event messages i.e. triggering points as below.
WF
On the other hand other than these basic event messages Plugin has huge set of event messages like AddItem, AddMember, GrantAccess, ModifyAccess, RemoveRelated and so on.

2. Workflows has limitations of Pre-event stages for some of the main events like delete has only before. And for plugin you can trigger the event on stages like pre-validation, pre-operation, post-operation. 

3. Some operations like deleting record from wizard workflow is not possible. So for this you can use custom workflow/Plugin.

One more simple rule you can remember- Whatever scenarios cannot be done with workflows, all that can be done using plugins.

Hope this will help you to understand Workflows and Plugins.

Filter Required/Regarding (partylist data type) fields using JavaScript in Dynamics 365 / MS Dynamic CRM

What is Issue?

Sometimes we need to filter out the lookup fields according to business requirement. So generally we try to apply custom filter using client side scripting (JavaScript). This filtration works for normal lookup fields (datatype Lookup), but when it comes to fields like Regarding object,Required,Optional fields (PartyList Datatype fields) on Activity forms(Appointments/Phone call) the script fails. It won’t filter the field continues to show default results for Accounts .

The Reason-

You will face this issue because the party list shows the results for all the entities like Accounts, contacts, lead,User and depending on the entity selected in “Look for” in Lookup More result window.

Solution-

The Solution for this issue is to set the “Look For” value before filtering the lookup to limit the search according to business requirement. Use the following code to set the “Look For” in Lookup More Window-

LookFor

This will set Look For as well as will apply the custom filter to your field.

C#: Unable to connect Dynamic365

What is the issue?

While coding with C#, developers struggles to connect with Dynamics 365. OrganizationService/ OrganizationServiceProxy object contains null and connection fails.

The Reason-

The reason behind this issue –
1. dll support
2. Wrong Connection String
3. Configuration settings
4. SSL/TLS setting

Solution-

solution according to the reason-
1. dll Support-
You should know which dlls are supported to connect Dynamics 365.
Many times the CRM versions differs and due to CRM upgrades the dlls used becomes outdated for new Versions. Currently many developers faces this issue if you are using Dynamics365 online version . Current version of CrmSDK is V9.0.0.7. and this should be used.
You can add reference of CrmSDK by using Nuget Package Manager-

NuCrmSDK

You can change the version according to recent updates by Microsoft.
2. Connection String-
Wrong connection string might be the problem and for Dynamics 365 online version you can use connection string like-

"https://<YourOrgName>.api.<CRMRegion>.dynamics.com/XRMServices/2011/Organization.svc"

<YourOrgName>– This is your Organization Name.
<CRMRegion>– This is the Region you choose while creating organization.

Also you can find this string navigating Customization-> Developer Resources in Dynamics 365.

Other way to connect CRM is providing each parameter Separately like-

 Microsoft.Xrm.Tooling.Connector.CrmServiceClient conn = new CrmServiceClient(uName, pwd, "NorthAmerica", _crmOrganizationName, isOffice365: true);

Also you need to provide Username and password(converted to secured password) Properly.
3.Configuration Settings-
Many times application throws an exception like “Metadata contains a reference that cannot be resolved” .
You provides the connection string properly, every thing is correct but still you found the OrganizationService/ OrganizationServiceProxy showing null.
This happens in some particular domain networks. In this case you have to enable the Proxy setting and for this add the following tag under the configuration tag to your Web.Config /app.config file-

<system.net>
<defaultProxy useDefaultCredentials=”true” enabled=”true”>
</defaultProxy>
</system.net>

This will only use the credentials provided by you in connection string.
4. SSL/TSL settings-
Your application fails to connect Dynamics365 CRM if it is using some particular security protocol. To connect successfully , you need to explicitly mention the security by adding the following line just before the connection establishment lines-

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Use Tls12/SSL/Tls11 according to security protocol used by Dynamics365 .

Hope this will be helpful to connect your organization.

Changes not reflecting on forms while importing managed solution to organization in MS Dynamic CRM

What is the Issue?

After importing managed solution to the organization, changes on the forms not reflects.
Example- MS Dynamic CRM developer made some changes on form which is already exists in organization,like changed display name of field on form or added some function on onChange event of some field, but when imported this changes through managed solution the labels not changed or function is not added on OnChange Event of field.

The Reason-

You will face this issue in case of unmanaged changes over managed entities in the organization.These managed entities maintains the customization even after importing new changes.

Solution-

We can divide the issue in two parts.
1. New events added to the form components.
2. The exiting field properties changed on the form.

The solution for issue 1-
These changes can be moved overwriting existing the managed solution which already contains the entity form which you want to update.

The solution for issue 2-
The simple solution for the first issue is to add new tab on form and move the updated fields to the new tab and format this tab as previous one.
Also, In this case, you can move the changes using same way mentioned for issue 1.

These both issues will never occur if you maintain the version of managed solution.
While deploying changes to MS Dynamic CRM try to maintain the version of managed solution.You can avoid creating new solution each time.It will avoid many failures which occurs during solution import or the updates on entities.

To maintain version and version history using the ‘Description’ and ‘Version’ fields of solution Information.
