The problem of this is in [Accion Cargo Modificado por] value. In database, this field has the value "RED_DESARROLLORED_SUP" and, after looking for SBL-DBC-00104 in google, I thought that the reason could be the length of this value, too long, but the fields [Accion Cargo Modificado por] and [Updated By] have the same length that the fields in database. Any idea about how put a length limit in a calculated value? can it be wrong because is a EBC? (I haven't this error in a similar BC with the same fields)
I have discovered the error. The text length in EBC had the same length that the fields in my table in database BUT the columns of that table in Siebel Tools hadn't the same length. That was why my EBC didn't work.
