When Opening SNA Manager, the Error "SNAOLE - FIELD CONFLICT. UNABLE TO CHANGE" is Displayed (275181)

SYMPTOMS

The following error message is displayed when the SNA Server Manager interface is started:

SNAOLE
FIELD CONFLICT. UNABLE TO CHANGE"

Note This error does not prevent SNA Server Manager from functioning normally.

CAUSE

This error message is displayed when the properties of a link service are modified after a connection has already been defined to use the particular link/adapter.

SNA Server Manager still works correctly because SNA Server Manager does not actually allow the change. However, the error is displayed.

WORKAROUND

To work around this problem, change the properties of the link service back to what is shown in the Connection Properties.

For example, in the Attachmate Advanced SDLC Link Service example that is described in the "More Information" section, change the link service back from "Switched: Modem-Stored Number" to "Leased."

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.

MORE INFORMATION

Steps to reproduce the problem

In the following steps, Attachmate Advanced SDLC Link Service is used as an example:

Add Attachmate Advanced SDLC Link Service (use External Link Services), and then configure it with a line type of Leased.
Add an SDLC connection that uses this link service. Notice that it shows up as a Leased Line in SNA Server Manager when you view the connection properties.
Modify Attachmate Advanced SDLC Link Service such that the line type is changed to something other than Leased (for example, Switched: Modem-Stored Number).

After you make this change, the SNAOLE error message is displayed every time SNA Server Manager is started.
