Hmmmm... I think you have a slight design issue to over come first.
For starters, the Job Number field your using is the wrong type. You must use an ID type field if you wish for your database to increase job numbers by a value of 1 each time.
The function you want in A,B,C and D by where it Clones the record and moves it to another folder also not advised if your using Job Numbers. If you do this, the Job Number ID Field will roll on once more because no two records can exist with the same ID number. If they did, that would defeat the entire purpose of job numbers. It's best that you move the record created only and not clone it.
To change “New Job” to “Blank” requires a query to be written that checks the current date, so this is no problem.
ok.....cool...but what i am trying to achieve with the cloning is that usually our billing clerk will use the same information from a job to create another part of the job to bill a separate charge after a bill is done. There can be up to 4 parts for each job with additional charges. So the same job number is used but with a letter at the end to identify it as a part of the job. For example the main job can be 2130000 and if another charge comes after a bill is done then she would clone the same job but name it 2130000 A. If another charge comes after this one then the primary job will be cloned again but name 2130000 B and so on....So i just wanted to simply the process by pressing the corresponding letter to create a clone and name the job number as mentioned above. Can this be achieved?
