RESTAPI Payload errors while trying to create inventory reservations against Transfer Order lines
As per standard design, once the Internal Sales Order is triggered through enrichment rules from the backing Transfer Order, we are trying to attempt the reservations against TO lines where the ISO is in a Waiting/Pause Step. Once the ISO, reached awaiting shipping , then the same payload works for inserting inv reservations against TO lines.

Kindly help us in concluding the design.
