Hello Techies,

I have a pre-validate plugin for duplicate detection.

based on the criterion if there is duplicate records found, I want to stop the record creation without throwing the Invalid Plugin Execution Exception.

Thanks in Advance.

You'd probably be better off moving your code to a plug-in which is registered on a custom action and then call the custom action using JavaScript when the form saves. This way you can get back an error message and display it in a friendly way to the end user.

In this case the source will receive the exception but client doesn't want it, as this is just a duplicate and wanted just to ignore.

Hi Viswanath,

This is how you can do it with C# code.

var context = (IPluginExecutionContext) serviceProvider.GetService(typeof (IPluginExecutionContext));
if (context.Stage == 10) //Pre-validation { //Stop Pre-validation code execution without throwing an exception } else if (context.Stage == 20) //Pre-operation { //Execute Pre-operation code } else if (context.Stage == 40) //Post-operation { //Execute Post-operation code }

Probably you can give the option to the external system for checking if the record already exists & ignore it before creating.

You have choice of creating alternate key, UPSERT operation or SuppressDuplicateDetection to decide. Better to stay away from prevalidate Plugin & InvalidPluginExecutionException.

If you are from external exe, actually you can wrap the code using block try and catch to surpress the error if you've got error unique right? It should be got error if you still want to have unique data insert into your system and not creating the error. It means that your code works normally.

If you don't want to get error stopper. Actually the easiest way is doing this one:

try{

service.Create(entity);

}

catch(Exception ex){

//Surpress the error weather got problem or not

}
