Parameter MESSAGE in structure BAPIRET2 not filled

Hi All,

I am receiving the following error message when saving my working time record in the portal: java.lang.Exception: Parameter MESSAGE in structure BAPIRET2 not filled. The data is getting saved but I have no idea where to look for this error.
