Creating Custom Fields
FIX Module allows you to create custom fields and include them in the messages that you exchange with your trading partners. A custom field is a user-defined field that is not part of the standard FIX specification, but can be created and added to an IS document type so that two trading partners can tailor messages to their specific needs.
FIX Module has an IS document type that corresponds to each FIX message type in the FIX specification. To create a custom field, you must edit the corresponding IS document type as indicated in the following instructions.
Important:
Both partners must define the same custom fields and use the same message structure to successfully exchange messages.
To create a custom field for a FIX message
1. In Designer, navigate to the WmFIXMessages package and open the FIX IS document in which you want to add a field.
For example, to add a new field to the FIX50AllocationReport, open the IS document wm.fix.rec.FIX50:FIX50AllocationReport in the WmFIXMessages package.
2. Add a new field to the IS document, and type the name of the new field.
3. Edit the Comments section and add the tag number of the field.
4. Repeat these steps for every new field that you want to add.
5. For the changes to take effect, reload FIX Module from either Integration Server Administrator (by clicking the Reload icon for the WmFIX package on the Management window) or from Designer (by right-clicking the WmFIX package and selecting the Reload Package option from the menu.
