• Key Concepts: 
  Field derivation schema is a feature of the FI-CA-INV Convergent Invoicing component of SAP. It allows users to define the rules for deriving field values from other fields in the system. This helps to ensure that data is consistent and accurate across the system. 
  
  How to use it: 
  To use field derivation schema, users must first define the rules for deriving field values. This can be done by selecting the fields that need to be derived and then specifying the conditions under which they should be derived. Once the rules have been defined, they can be applied to any field in the system. 
  
  Tips & Tricks: 
  When defining field derivation rules, it is important to consider how they will affect other fields in the system. For example, if a rule is defined that will cause a field to be derived from another field, it is important to consider how this will affect other fields that rely on that same field for their values.
