Creating and Managing Your Model › Creating a CA 2E Design Model › Open Access

Open Access

When you enter a CA 2E model you specify one of the following three user types:

• *DSNR (Designer)
• *PGMR (Programmer)
• *USER (User)

The user type you specify determines when you can access the model and what types of changes you can make.

The Open Access parameter OPNACC lets you specify whether multiple designers (*DSNR) and programmers (*PGMR) can work in the model at the same time. This parameter sets the YOPNACC model value. The values for this parameter and the implications of each are as follows:

• *NO—Restricts access to the model to only one *DSNR at a time. If a designer is working in the model, programmers and other designers are denied access to the model.
• *YES—Allows multiple designers and programmers to work in the model concurrently. enables file and field locking to prevent two designers from updating the same file or field at the same time.
