Field help (VALDETEAS) 

It is the value that the field will take during the application of the associations. The entry of this value is optional.
If no value is entered for a determined field, this field will be ignored during the association whatever the setup done for the Forced flag may be: the potential value that is already in the field will not be deleted.
..\FCT\SEEINFOThe value of the admission coefficient cannot be entered in this column; the entry is carried out in the Coeff. column.
