Lord 2 - fields not being transferred to ECC

Hi All

We are doing are first project using lord 2 api.

I have followed this blog by Tony Rosenthal,but i am not getting any data transferred between ECC and CRM.

ECC Lean Order: Adding a field to the LORD API

The sales order is being created correctly in the ECC system.

We are on CRM 7 ehp1.

I have duplicated the steps to the letter, and I am getting no data transferred to ecc for field vbkd-ihrez.

Also, I have noted that when I enter a value in the webui in the zzihrez field that I have created and if I hit return, the field value dissapears.

Any help would be greatly appreciated.

Thanks

Darren
