Hi Purnima,

Pre-Validation: is before the record even reaching the stage of pre-operation,

so means not yet saved, it is the first layer,usually used for validation, but not many people use this, usually will just use pre-operation.

Please check below example how to use pre validation stage.

Thanks,

Check this - there is a nice explanation:

stackoverflow.com/.../when-would-i-register-a-crm-2011-online-plugin-for-pre-validation-stage

I believe 3 things to consider are:

- Pre-validation runs outside of the main transaction (you can do CRUD operations there, and they won't rollback if an error happens after)

- Security checks happen after pre-validation

- Cascade operations happen after pre-validation (but, possibly, before pre-operation)

Hi Purnima ,

There may be many scenario you can use pre-validation messages. But two things you need to remember when you are going to implement pre-validation plugin.

Plugin in Pre-validation does not join the database transaction, that means whatever you are doing in pre-validation it will not going to rollback if any error happen in the other stage of the plugin.So be careful when you are using pre-validation operation.

Secondly Pre-validation does no check any security access so it might be happen you want to retrieve some records which you don't have permission but you retrieved to validate .

In summary I can say pre-validation you can use when you really need only validation purpose not for main operation.

Hope this helps.
