Problem

How and where to add new Trading engine and Custom metadata attributes in B2Bi.

Resolution

Please check /Integrator/solutions/config/b2bx/server/metadata_attributes.cfg

# NOTE:
# Do not change this file.
- If there is a need to add new additional attributes,
- then create a new empty metadata_attributes.cfg file in the directory $B2BI_SHARED_LOCAL/config/b2bx/server,
- create the directory if needed, and add the new attributes using the same syntax as used in this file.

**Configure custom attributes to be used in metadata criteria rules

1. For optional trading engine attributes only:
   1. From <<span class="mc-variable axway_variables.Product_Short_Name variable">B2Bi</span>_installation_directory>/Integrator/solutions/config/b2bx/b2bxgi, copy the b2bxgi_attributes.txt file to $B2BI_SHARED_LOCAL/config/b2bx/b2bxgi.
   2. Enable the attribute that should be sent from the trading engine to the integration engine by setting the value to 1.
   3. Example: Direction = 1
   4. Restart B2Bi.
2. In the $B2BI_SHARED_LOCAL/config/b2bx/ folder, create a folder named server.
3. In $B2BI_SHARED_LOCAL/config/b2bx/server, add a file named metadata_attributes.cfg.
4. Add the custom attributes to $B2BI_SHARED_LOCAL/config/b2bx/server/metadata_attributes.cfg, with the following structure:
   • For custom metadata attributes:
   • Message Attribute: CustomAttribute1=string
   • For optional trading engine attributes:
   • Trading Engine: TradingEngineAttribute=string
