Customize Messages in Package Log in BPC

Dear Experts,

                    I have created on ABAP Program to validate data (BPC Cube) for certain cases, and this ABAP program is called using BADI. If Validation of Data fails, then those error messages must be written in Package log in addition to package status.

                    Is this possible?

                    for example,

                    if data is validated and 2 Error messages are generated using program say Error1, Error2.

                    then package log will contain total 3 lines,

                    eg,  1: Package Log Status as -- Failed

                           2: Error1 -- Customize Error Message

                           3: Error2 -- Customize Error Message     

                     PFA For Reference.
