Continued to check the screen scrape, to find the cause of the error in the process, as per checking, the screen scrape still sending an incorrect transfer number at the middle of the process, checked the data, as per checking, it has no difference in other data, and when re-running the screen scrape, the process executed the same transfer number successfully but is not successful at previous execution, modified the screen scrape to add an echo and comment to found out where it is inserting incorrect value.
