Not all types of MRM models support optional fields.
You'll need to be more specific about your model and the type of data you're trying to parse before we can help. |

For Ex

You can't use optional fields within fixed length types. They have to be present in the input message (even if they're blank).
If you are trying to ADD data to a message, then you can model the message twice - once as the input message without the field and once as the output message with the new field.
However, you can have optional fixed length types. That is, you can have an optional element of a fixed length type - which it sounds like you're trying to do. So your model should be something like
| Code: |
Message
Records
NAMelement (required)
MORelement(required)
F2Aelement(optional)
RPIelement(required)
CNFelement(required) |
Each XXXelement is of the compound type that describes that record - which may be fixed length or variable elements tagged delimited. The Records type is a compound type of Choice composition, and is of Tagged Delimited type. The Message type is also of Tagged Delimited type and contains a single element of Records type which is a repeating element.
The tag length on all types is 3. And you set the tag on each XXXelement to be the tag, which for the NAMelement would be NAM.
If I understand your question properly, that is. |
