While enhancing a custom ORU^R01 schema, there was a Z segment at the end (that I did not want to place in the ZSegments message part.
I went happily creating the schema, deployed it and ran it, and received the following errors:
Event Type: Error

This is the schema that I had created:
If I look at the documentation on Z Segment creation I see this:
Type the name of the field, starting the name with the first three digits of the segment name, followed by a period and the number of the field, followed by an underscore and then a short description of the field. The description should be one or a series of words, without spaces, with the first letter of each word capitalized. Press Enter.
To create a field with components, create the field as a record, and then create a child element of that record for each component. To create a field with subcomponents, create the field and components as records, and the subcomponents as child elements. Note that subcomponents cannot be composite data types. For example, for the segment named ZPP_PatientPreferencesSegment, you might create a ZPP.1_Dietary field and a PD.1 Allergies component with a PD.1.1_FoodGroupAllergy subcomponent. The PD.1.1_FoodGroupAllergy subcomponent would have to be a simple data type.
So this is a special behavior for the Z Segments, where you MUST use the period instead of the underscore if the first character is a number, notice the difference between two segments:
