Add measurement point / counter

Hello,

I am facing the problem that I need to add a counter value to a measure point. For this I have the equi no, the pos of the counter and the value I have to add. If the measurement point does not exist, I have to add one by creating it with the information about the pos and measurement point.

Could someone tell me if there a some BAPIs that help finding the measurement point by equi no and pos? How to add the measurement point if it is not existing? I just saw some code that reads the information in the tables but is there something more standardized?

Thanks a lot, Vanessa
