Hello Deepak,
The consumer in "initial flow contexts" refers to the right consumer maintained in the table CRMCONSUM (the table exists in both CRM and ERP system).
In the table, you are able to set the consumer as "active" or "inactive".
Also, for both upload and download, the proper entry should be maintained in table CRMRFCPAR in ERP system for the right consumer.
Hope this answers your query.
Thanks,
Best regards,
Julin Xin
