AggregateIHData strategy error (dateTimeToBigDecimal)
Summary
Post upgrade to Pega 8.1.1 and Strategic Application 8.1.1, error occurs when running a Strategy rule.
The strategy uses a Set property strategy component.
@if(CountResponses.CountOffers = 0, 0, @(Pega-RULES:DateTime).dateTimeToBigDecimal(.pxOutcomeTime, "DateTime", tools))
However, the same Strategy works correctly in the Pega 7.2.2.
Error Messages

Steps to Reproduce
- Upgrade Pega 7.2.2 to Pega 8.1.1.
- Create a Strategy with an Interaction History (IH) Import shape and a Property Set shape in the PegaMKT-Data-Customer class.
- Use the following expression and test run the strategy.
@if(true, @(Pega-RULES:DateTime).dateTimeToBigDecimal(.pxOutcomeTime,"DateTime",tools), 0)
Root Cause
A defect in Pegasystems’ code or rules.
The DateTimeToBigDecimal output section had both Java Type and Pega Type defined. However, they were different.
The issue occurred due to the generation of code from the below expression,
@if(true, @(Pega-RULES:DateTime).dateTimeToBigDecimal(.pxOutcomeTime,"DateTime",tools), 0)
Resolution
As a local-change, remove the @if call and use a general ternary expression.
For example:
Property Set:
Target: myIntProp
Source: CountResponses.CountOffers = 0 ? 0 : @(Pega-RULES:DateTime).dateTimeToBigDecimal(.pxOutcomeTime, "DateTime", tools)
Modify the Source to (CountResponses.CountOffers = 0) ? 0 : @(Pega-RULES:DateTime).dateTimeToBigDecimal(.pxOutcomeTime, "DateTime", tools)
