Abstract: Described herein are techniques for automatically substituting information into orders generated by a data record system prior to persisting the orders in storage of the data record system. The techniques store substitution groups of data entities that store data associated with respective substances (e.g., medications). When order templates (e.g., medication regiments) are generated by the data record system, the techniques automatically modify the order templates (e.g., by substituting data entities in the orders) based on data entity substitution configurations of the substitution groups. Information from the modified order templates is input into orders before the orders are persisted in storage of the data record system.
