Expense types posting issue

HI,

I have two expense type BRFR & MEFC. Configuration wise both are same and only difference is the wage types assigned to them. BRFR assigned to wage type 2961 and MEFC 6517.

In posting run BRFR does not make posting from TRV into FI, whereas MFEC posting done from Travel into FI.

Why in posting these expense types behaving differently. Is it wage types responsible for that or there is something i mised in configuration.

Please suggest.

Thanks
