Many thanks,

While preparing a demo I nailed the problem:
I name the merge fields after TableName.ColumnName pattern.
Previously, in order this to work I had to rename all columns after this pattern: e.g. column Id in table Customers was renamed to Customers.Id. Now this doesn’t work, I had to remove column renaming.


Hi Georgi,

Thanks for your inquiry.

Well, if the region in your template document is defined by something like TableStart:Customers and TableEnd:Customers, in this case please note that the region name ‘Customers’ should correspond to the name of the table (e.g. the name of DataTable). Also, the name of the merge fields that are placed inside your region should correspond to the fields of your data source (table columns). For example, if the name of the merge field is Customers.Id then your DataTable must has a column named Customers.Id.

If we can help you with anything else, please feel free to ask.

Best regards,
