Manage auto increment column values in Mosaic Decisions

I have a table in which auto incremental sequence is defined for a key column.

Problem Statement-

Source_table has column ID with values 101, 102, 103 so on and Destination_table has column ID with values 1201,1202,1203.. and is in incremental form.

Source_table

Destination_table

Now, in Mosaic I am able to read the data from the Source_table, but while writing into the Destination table, the values of Destination_table.ID gets overwritten by the Source_table.ID values.

Is there any way that I can preserve the sequence of my Destination_table in Mosaic?

Yes, you can use the Skip Insert and Skip Update functionalities available in the writer node for Upsert write mode, in which it will skip the sequence coming from the input and preserve the sequence at the destination column.

To achieve this, in the Writer Node Configuration menu, select the Write Mode as Upsert and drag in the columns you wish to preserve the sequence for to the Skip Insert and Skip Update, as shown below:
