Validate Payroll is working weirdly for Global Transfer

Summary: We have Default Payroll rule which is working but not for Global Transfer. The use case is 74 for FORD. We also tried a Validation Rule to throw an error if the payroll is incorrect but it is getting trigerred after the Assignment Section, please help. We dont have a use case for this but considering validations re expected to work in Redwood please let us know if this is feasible. I referred to this document which says a combination of default and validate would work for Global Transfer. https://blogs.oracle.com/fusionhcmcoe/post/default-validate-payroll-autocomplete-rule
