Cannot import India tax lines with STANDARD taxable_event post GST patch application

I am trying to load AR invoice via Interface using 'Autoinvoice Import Program' after inserting records in RA_INTERFACE_LINES_ALL and JAI_NTERFACE_LINES_IALL and JAI_INTERFACE_TAX_LINES_ALL.

Case 1: When taxable_basis = 'EXTERNAL', transaction is created in AR and IL tax details are also loaded as expected

Case 2: When taxable_basis = 'STANDARD' and we provide tax_category_id, transaction is created in AR but IL tax details are also NOT loaded. It seems JAI interface table data is not even considered

Backgroud: We are importing non-item transactions, using Memo-lines and therefore do not use Order Management in this flow.
