Hello Kets,
Whatever posting you have shown in the screenshot for system entry is correct:
DR AP
CR Noted Payable
==
Even if you enter the tax data in the Open Item Payable migration, that is entered as information/statistical only.
Usually, For Open items on tax accounts in the legacy system.
Solution: Tax must be reported and paid before migration. Choose a cut-off date accordingly.
Please refer to Tips to Avoid Typical Mistakes section from the help document Migration of Financial Accounting Data
Thanks
