Step 4: Create a trading capability

A trading capability connects your outbound transformer to specific Amazon S3 directories and defines the automated workflow. It monitors your input directory for new JSON files and automatically processes them using your transformer, placing EDI results in the output directory.

To create an outbound trading capability

1. In the AWS B2B Data Interchange console, choose Trading capabilities.

2. Choose Create trading capability.

3. In the Trading capability settings section, enter:

   • Trading capability name: Outbound-850-Generation

   • EDI direction: Select Outbound

   • X12 version: Select 4010

   • X12 transaction set: Select 850 (Purchase Order)

   • Apply transformer: Select JSON-to-X12-850-Transformer

4. In the Configure directories section:

   1. Input directory: Choose Browse S3 and select my-b2bi-outbound-input-bucket-your-account-id.

   2. After selecting your input bucket, the console displays a Copy policy button. Choose Copy policy to copy the automatically generated input bucket policy to your clipboard. Save this policy text in a text editor for the next step.

   3. Output directory: Choose Browse S3 and select my-b2bi-outbound-output-bucket-your-account-id.

   4. After selecting your output bucket, choose Copy policy to copy the automatically generated output bucket policy to your clipboard. Save this policy text in a text editor for the next step.

      Note

      You'll validate your S3 setup after configuring the bucket policies in the next section.

5. Choose Create capability.

Configure Amazon S3 bucket policies

To apply bucket policies

1. Navigate to your input bucket in the Amazon S3 console.

2. Choose the Permissions tab.

3. In the Bucket policy section, choose Edit.

4. Paste the input bucket policy you copied from the trading capability configuration in the previous step.

5. Choose Save changes.

6. Repeat steps 1-5 for your output bucket with the output bucket policy.

7. Return to the trading capability configuration page and choose Validate input S3 setup to verify your input directory configuration. This checks bucket region, EventBridge events, bucket policies, ownership, and KMS permissions.

8. Choose Validate output S3 setup to verify your output directory configuration. This performs the same checks as input validation plus verifies ACL is disabled.

   Note

   Now that you've configured the bucket policies, the validation should pass without warnings. Any remaining warnings can typically be ignored as they are approximations.
