I agree with Gary and John – you really need to provide context when you ask a question. Nevertheless, I've got a free moment, so I'll give it a try: It appears to be a description of qualifications job-seekers should have in order to be considered. (It's something you might read in a job announcement.) It's not written as a sentence, but rather as a bullet point. It means that if the applicant has a professional designation (licence, certificate, degree – it depends on the occupation), it would be an asset (of value / helpful).

"professional designation an asset" does not make sense.

Can you give more context? It doesn't make much sense as it is. And please try to punctuate correctly. You need a space after your comma.
