Sync Transform after modifying target database

Using ConnX web interface, create a .cdd file, connected mainframe and SQL server native client server. These server have 2 databases and trying to sync tables from IDMS mainframe to SQL server.

Successfully created transformation and sync the tables.

database_1a.dbo.table_1a > database_2a.dbo.table_2a

After sync, I have updated the target source (SQL server), modified cells in target table. And tried to sync transform again (note: while suyncing, used select existing table and selected the same table database_1a.dbo.table_1a > database_2a.dbo.table_2a).

But receive and error while preforming sync after mofdification -
Error:
Unable to PassPrepare. >>> STAT:2 ERR:0 SQLSTATE:S1000 problems with IColumnsInfo → GetColumnsInfo()STAT:2 ERR:-2147217900 SQLSTATE:S1000 Microsoft SQL Server Native Client 11.0 : Deferred prepare could not be completed.STAT:2 ERR:-2147217900 SQLSTATE:S1000 Microsoft SQL Server Native Client 11.0 : Communication link failure (transform_error)

How to resolve this issue.

What I am trying to achieve is, once the sync is made, modified in target database, and synced again with source, I want new rows to be added, as there is modified rows different from source.

Please kindly open a support ticket for this resolution of this issue.
