Customize X12 for US CBP

We have a requirement to send an ANSI X12 004060USCBP, which seems to be an approved ANSI X12 version that WM doesn’t suppport. It seems similar to 5010, although some segments have additional fields.

I’ve copied the 5010 schema and am trying to add the additional fields. I’ve created a custom dictionary in which I’m creating the segments requiring additional fields, using field references back to the original 5010 dictionary.

(confused yet??)

So far, the wm.b2b.edi:convertToValues just won’t map the custom segments.

Any suggestions, or anyone worked with this standard before?

Are you utilizing any formatServices of the 5010 schema??Also what have you changed in the Schema/Dictionary??
