When the "Apply Changes" and/or "Store Changes" replication options are enabled,the ordinal position of the "Data start" header column cannot be zero.

Hello @Sehwag ,

Welcome to Qlik Community forum and thanks for reaching out here!

It seems the "Data start" is a custom header column rather than prebuilt header column. Would you please share the expression and what's the source endpoint database type?

thanks,

John.

Hello @Sehwag ,

Thanks for the update. We need to know the "Data start" column expression, it's better a support ticket with Diag Packages.

thanks,

John.

@Sehwag -- what is the question here?

Obviously the data start column cannot be zero apply/store as there must at least be an operation column first.

You may also need to provide the table name, a timestamp and a username.
