A VAT breakdown (BG-23) with VAT Category code (BT-118) "IPSI" shall not have a VAT exemption reason code (BT-121) or VAT exemption reason text (BT-120).
The IPSI (AG) VAT breakdown group carries a VAT exemption reason, but VAT is actually being charged at this category, so there is nothing to exempt.
Remove the exemption reason text (BT-120) and reason code (BT-121) from that group. If you really are not charging VAT, the category code is the thing to change.
