Declare Expression is not working in Pega 7.1.7



A Claim work object contains a page list of AccountingTransaction items, each of which consists of one or more AccountingEntries. A Declare Expression has been created to get the sum total of debit accounting entries for each AccountTransaction; however, the Declare Expression is giving the total for all of the AccountingEntries items in the Claim and not just for a single AccountingTransaction.

Error Messages

Not Applicable.

Steps to Reproduce

  1. Create work and data classes so you have the following page structure.
    • ​​pyWorkPage
      • AccountingTransaction(1)
        • AccountingEntries(1)
        • AccountingEntries(2)
      • AccountingTransaction(2)
        • AccountingEntries(1)
        • AccountingEntries(2)
  2. Create a Declare Expression to sum the amounts from the AccountingEntries when the type is debit.
    • ​​Set TotalAmount = Sum of Parent.AccountingTransaction().AccountingEntries().Amount using entries in which @(Pega-RULES:String).equalsIgnoreCase(.DebitCredit, "Debit").

Root Cause

The condition used to sum the values was incorrect.


Perform the following local-change:

Change the sum condition from "Parent.AccountingTransaction().AccountingEntries().Amount" to ".AccountingEntries().Amount".
