Error "FAILED: Tax calculation call to connect supports 15,000 items at maximum." when using Vertex
If you have Vertex Tax Connector integrated with your tenant, when using Order API calls to create Subscription, and there are too many Rate Plans included in one single Create Order call, it's possible to encounter the error "FAILED: Tax calculation call to connect supports 15,000 items at maximum."
There are two approaches to avoid this error:
1. In the request payload, split the Order Actions into multi Orders to reduce the number of Rate Plans included in the single call;
2. Set the "Calculate Tax for TCB and ELP Metrics?" option to "No" in Subscription Settings so Tax calculation will not happen during the API call process.
