Problems with SEPA OSS notes

Hi experts,

I implemented some OSS notes and now I'm having problems with the transport, these notes are:

2235866

2243546

2245270

2247937

The error is given in program LSEPA_MNDID_CUSTT00. Comparing with other clients that have already implemented those notes, it seems that it hasn't been updated because there is no reference to the part:

*...processing: V_T028Y_SEPA....................................*

(...)

When tranpsorting the order I get the error "V_T028Y_SEPA-REASON_CODE doesn't exist".

I don't know if I've missed any step when implementing the notes.

Thanks in advance,

María
