Answer: The problem is still complex mandatory ATO rules. So user still have to enter correct codes. So A and A doesn’t work. Possible are: A for partnership worksheet and P for form. Or none of the codes at all. If user doesn’t want P for form then I suggest second option is acceptable.
A valid combination of deduction codes should be presented in both partnership worksheet and partnership section. This is mandatory for ATO. User can read more about codes at https://www.ato.gov.au/Individuals/Tax-return/2021/Supplementary-tax-return/Income-questions-13-24/13-Partnerships-and-trusts-2021/.
