You can use change request header information in conditions or driving values when creating rules.
Value Check or Derivation Rule
Create the rule according to Value Check Rule or Derivation Rule instructions. When creating the condition, choose CR_HEADER from the Entity box and select which type of information to use from the Attribute box.
Multivalue Validation or Multivalue Derivation Rule
Create the rule according to Multivalue Validation Rule or Mutlivalue Derivation Rule instructions. When adding the validating or driving attribute, choose CR_HEADER from the Entity box and select which type of information to use from the Attribute box.
Rules Using Notes/Attachments
The presence (or absence) of Notes/Attachments can be used as conditions in single or multivalue validation and derivation rules. For example, in this rule, if the base unit of measure is G – Gram, and both note(s) and attachment(s) are present in the change request header, the value of weight unit will be derived to be the same as unit of measure.
In the change request below, both a note and an attachment have been added to the change request header. The base unit of measure is G – Gram. Therefore, the weight unit has been derived according to the rule.
