Auto assign a lookup field with Test Account

Hi All,

I have customized the Case entity and in no need of "Customer" field. However, I couldn't remove it from the form, as it's mandatory. So, I decided to hide it in the form and then auto assign the "Test Account" through Business Rule.

However, it failed in QA or PROD, cos the business rule is looking for the same "Test Account" based on the GUID and not by name.

I was told that, JavaScript is the only way to auto assign "Test Account", which will work in QA and PROD as well.

As I am not familiar with javascript, can someone help me with the code for this functionality?

Thanks,

Praveen.
