Dear team,

Can we put condition in CoC? I mean if condition is true then only CoC will execute else not

If not possible then if any workaround is there?

Please give me the thoughts. thanks!

No, it's not possible. CoC means that you create an extension class and extend a method; there is no way how to make the existence of a class or a method conditional. It's either there or not.

But you can put conditions to the method code.

Maybe you mean whether you can conditionally call the base method (with the next keyword). It's not normally possible, unless the base method is explicitly marked as replaceable.

Hi @CU10121822-0,

It is not recommended to ignore the call to next, but you can do so with an exception !

Hi, I tried in below way:

[ExtensionOf(classStr(SalesTable))] final class SalesTable_Extension { public void update() { try { // Pre-logic with condition if (this.CustAccount == 'CUST001') { info("Before update: Special customer logic"); } next update(); // Post-logic with condition if (this.SalesStatus == SalesStatus::Invoiced) { info("After update: Sales order invoiced"); } } catch (Exception::Error) { error("Error occurred while updating SalesTable"); throw; // always rethrow in CoC } } }

So, here what I understood, the condition is returned TRUE or False, it's doesn't matter, CoC will execute always.

am I correct?

Yes, once created / defined, the CoC will always be called by the system. Adding conditions in the your extension code is probably the solution you are after.

Not sure if I follow you and I might be on a wrong track here. That depends on the code your CoC code. If you are worried about performance, the fact the CoC code is called by the system does not really add much performance overhead on it's own provided there is no database query / update etc. or other time consuming code like calling a web service etc. So, if you have a CoC with a condition that only executes your logic when necessary, it does not really add noticeable overhead.

What adds performance overhead is querying or updating the database, or calling other things like web services etc..

Hi,

A small clarification. Your CoC coding will be always executed. The next() call is mandatory. You can add coding before and after the next() command.

You now have conditions in your X++ coding. The condition will be evaluated and will be true or false. So, in your example, if the customer account number is CUST001, then you will get your info message, whereas for any other customer, the message is skipped.

If this is what you meant by a condition, then this is not useless. In many cases, I used such condition in X++ coding on CoC methods. I think that is also what Anton wanted to say in the message just after your code example.
