Note - Before asking the question, I googled, searched in softwareag and also tried with a sample code. But I didnt get an answer.
I was trying to find the disadvantage of using Update with Read physical. I read in a resource that Read by ISN is preferred compared to Read Physical to do updates. “Potential Double updates problem” in read physical wont be present using Read by ISN.
So anybody can explain about this issue? I tried updating all the records of a file for one field using Read physical and I didnt get any issue.
