so in salary slip v15 there is this code in salary_slip_loan_utils.py .
however when checking the salary slip structure , there is no table called loan , in v14 the table exist , but not in version 15 . so where is the table ?
Loan has its own separate app now
@bahaou try installing the app that @mohitchechani mentioned, because loan repayment will be set if the lending app is installed, as you can see in the code on line 24.
