Filling voucher type (VoTp) in Voucher table (WaVo) doesn't fill debit and credit account fields.

[Simonas]

Hello,

we started getting problem that when filling voucher type (VoTp) in Voucher table (WaVo) doesn't fill debit and credit account fields (DbAcNo) (CrAcNo) anymore. Voucher type table has all accounts filled to corresponding voucher type. It worked before and we cant find  the reason why it doesn't work anymore.

Maybe anyone has a tip what the problem could be?
