I have been trying to call the offer engine via enrichment and have been following this document - https://docs.campaign.adobe.com/doc/AC6.1/en/PDF/interaction-v6.1-en.pdf (Page 85).
I have followed all the steps as mentioned in the document but when I run my workflow, I get the below error in my enrichment activity -
09/08/2018 15:06:57 No joining condition is defined for the 'upsellofferproposition' link ('Enrichment' stage)
Note : I have been trying to use enrichment for specifying an offer or an offer engine call. And the document doesnt mention any linking/join for this activity.
Also, We are using custom tables to store proposition instead of the Adobe OTB tables.
