In draw loop we can merge the Salesforce record fields related to only the main object where we created DDP (Dynamic Document Package). To resolve this issue, we can use SOQL query in draw loop to fetch unrelated record or all child records.

After you have successfully installed Nintex Draw loop, you can start creating relationships for your Salesforce data, creating templates to generate documents based on the data, and can specify where and how output documents should be delivered.
