Dear Dzung,

this should be fairly simple: You activated the validation and this goes through all your fields and checks the required boundaries. Your OMP_O09_ORDER is defined as having minimum one instance (have a look at the minimum occurrence attribute of the field).

Regarding your empty fields: The field delimiter is defined as r or carriage return. However your test file provides rn also known as carriage return+line feed. Just switch your text editor to using mac line endings (these are just r) and the file parses just fine.

Best regards,
Matthias

Dear Matthias,

Thank you a lot for your advice. I forgot about the line ending character. I also thought the file has problem because before I added ZD2 segment to it, my system can work well with at least 5 times test. But I don't know what problem can be, thank you a lot.

Best regards,
Dzung
