FATAL
The official rule text below states the exact requirement your invoice does not meet. The referenced business terms (BT-xx) identify the fields involved.
How to fix it
- Locate the elements for the business terms (BT) named in the rule text.
- Compare your values against the stated requirement and correct them.
- Re-validate - fixing one rule sometimes reveals a related one.
