dynamic_filters bit Indicates whether the publication is filtered using a parameterized row filter.

0 = The publication is not row filtered.

1 = The publication is row filtered.
snapshot_in_defaultfolder bit Specifies whether snapshot files are stored in the default folder:

0 = The snapshot files are in the default folder.

1 = The snapshot files are stored in the location specified by alt_snapshot_folder.
alt_snapshot_folder nvarchar(255) The location of the alternate folder for the snapshot.
pre_snapshot_script nvarchar(255) Pointer to a .sql file that the Merge Agent runs before any of the replication object scripts when applying the snapshot at the Subscriber.
post_snapshot_script nvarchar(255) The pointer to a .sql file that the Merge Agent runs after all the other replication object scripts and data have been applied during an initial synchronization.
compress_snapshot bit Specifies whether the snapshot written to the alt_snapshot_folder location is compressed into the Microsoft CAB format. 0 specifies that the file is not compressed.
ftp_address sysname Network address of the File Transfer Protocol (FTP) service for the Distributor. Specifies where publication snapshot files are located for the Merge Agent to pick up, if FTP is enabled.
ftp_port int The port number of the FTP service for the Distributor.
ftp_subdirectory nvarchar(255) The subdirectory where the snapshot files are available for the Merge Agent to pick up.
ftp_login sysname The user name used to connect to the FTP service.
ftp_password nvarchar(524) The user password used to connect to the FTP service.
conflict_retention int Specifies the retention period, in days, for which conflicts are retained. After this time, the conflict row is purged from the conflict table.
keep_before_values int Specifies whether synchronization optimization is occurring for this publication:

0 = Synchronization is not optimized, and the partitions sent to all Subscribers will be verified when data changes in a partition.

1 = Synchronization is optimized, and only Subscribers having rows in the changed partition are affected.
allow_subscription_copy bit Specifies whether the ability to copy the subscription database has been enabled. 0 means copying is not allowed.
allow_synctoalternate bit Specifies whether an alternate synchronization partner is allowed to synchronize with this Publisher. 0 means that a synchronization partner is not allowed.
validate_subscriber_info nvarchar(500) Lists the functions that are being used to retrieve Subscriber information and validate the parameterized row filtering criteria on the Subscriber.
ad_guidname sysname Specifies whether the publication is published in the Microsoft Active Directory. A valid GUID specifies that the publication is published in the Active Directory, and the GUID is the corresponding Active Directory publication object objectGUID. If NULL, the publication is not published in Active Directory.
backward_comp_level int Database compatibility level. Can be one of the following values:

90 = SQL Server 2005 (9.x).

100 = SQL Server 2008 (10.0.x).
max_concurrent_merge int The maximum number of allowed concurrent merge processes. A value of 0 for this property means that there is no limit to the number of concurrent merge processes running at any given time. This property sets a limit as to the number of concurrent merge processes that can be run against a merge publication at one time. If there are more snapshot processes scheduled at the same time than the value allows to run, then the excess jobs will be put into a queue and wait until a currently-running merge process finishes.
max_concurrent_dynamic_snapshots int The maximum number of allowed concurrent filtered data snapshot sessions that can be running against the merge publication. If 0, there is no limit to the maximum number of concurrent filtered data snapshot sessions that can run simultaneously against the publication at any given time. This property sets a limit as to the number of concurrent snapshot processes that can be run against a merge publication at one time. If there are more snapshot processes scheduled at the same time than the value allows to run, then the excess jobs will be put into a queue and wait until a currently-running merge process finishes.
use_partition_groups smallint Specifies whether the publication uses precomputed partitions.
dynamic_filters_function_list nvarchar(500) A semi-colon delimited list of functions used in the publication's parameterized row filters.
partition_id_eval_proc sysname Specifies the name of the procedure run by the Merge Agent of a Subscriber to determine its assigned partition ID.
publication_number smallint Specifies the identity column that provides a 2-byte mapping to pubid. pubid is a globally unique identifier for a publication, whereas publication number is unique only in a specififed database.
replicate_ddl int Indicates whether schema replication is supported for the publication.

0 = DDL statements are not replicated.

1 = DDL statements executed at the publisher are replicated.

For more information, see Make Schema Changes on Publication Databases.
allow_subscriber_initiated_snapshot bit Indicates that Subscribers can initiate the process that generates the snapshot for a publication using parameterized filters. 1 indicates that Subscribers can initiate the snapshot process.
dynamic_snapshot_queue_timeout int Specifies how many minutes a Subscriber must wait in the queue for the snapshot generation process to begin when using parameterized filters.
dynamic_snapshot_ready_timeout int Specifies how many minutes a Subscriber waits for the snapshot generation process to be completed when using parameterized filters.
distributor sysname The name of the Distributor for the publication.
snapshot_jobid binary(16) Identifies the agent job that generates the snapshot when the Subscriber can initiate the snapshot generation process.
allow_web_synchronization bit Specifies whether the publication is enabled for Web synchronization, where 1 means that Web synchronization is enabled for the publication.
web_synchronization_url nvarchar(500) Specifies the default value of the Internet URL used for Web synchronization.
allow_partition_realignment bit Indicates whether deletes are sent to the subscriber when modification of the row on the publisher causes it to change its partition.

0 = Data from an old partition will be left on the subscriber, where changes made to this data on the publisher will not replicate to this Subscriber, but changes made on the Subscriber will replicate to the Publisher.

1 = Deletes to the Subscriber to reflect the results of a partition change by removing data that is not longer part of the Subscriber's partition.

For more information, see sp_addmergepublication (Transact-SQL).

Note: Data that remains at the Subscriber when this value is 0 should be treated as if it were read-only; however, this is not strictly enforced by the replication system.
retention_period_unit tinyint Defines the unit used when defining retention, which can be one of these values:

0 = Day.

1 = Week.

2 = Month.

3 = Year.
decentralized_conflicts int Indicates whether the conflict records are stored at the Subscriber that caused the conflict:

0 = Conflict records are not stored at the Subscriber.

1 = Conflict records are stored at the Subscriber.
generation_leveling_threshold int Specifies the number of changes contained in a generation. A generation is a collection of changes that are delivered to a Publisher or Subscriber.
automatic_reinitialization_policy bit Indicates whether changes are uploaded from the Subscriber before an automatic reinitialization occurs.

1 = Changes are uploaded from the Subscriber before an automatic reinitialization occurs.

0 = Changes are not uploaded before an automatic reinitialization.
