Field PTRV_UTIL_ABZUG-FRSTK not in field control table

Hi Experts,

While Creating Travel Request and press Save button, I received the following message:

No authorization for personnel number 50099100

Message no. 56090

Then after ignoring this and pressing Save button again, I received the following message:

Field PTRV_UTIL_ABZUG-FRSTK not in field control table

Message no. PTRA_WEB_INTERFACE084

Any help will be appreciated.

Regards,

Fausto
