Specifies whether VTAM® dynamically adds entries to the adjacent SSCP table.

If you specify SSCPDYN=NO, you might have to define additional adjacent SSCP tables. When an application issues a CLSDST PASS macroinstruction during session setup, VTAM does not build an adjacent SSCP table in the application's network. (When SSCPDYN=YES is coded in the application's network, VTAM builds such a table automatically.)

This start option is closely related to SSCPORD. See z/OS Communications Server: SNA Network Implementation Guide for information about how to use these two start options.
SSCPDYN=NO
Specifies that VTAM does not add new entries unless it is the owner of the resource. The owner is determined by the CDRM operand of the CDRSC definition statement, or by session initiation.
SSCPDYN=YES
Specifies that VTAM adds a new entry to a cross-domain resource's adjacent SSCP table whenever it receives a session initiation request from the resource through an SSCP that is not already in the table.
