I am new to SAP BW, i am facing problem with enhancing issues. I enhanced the LIS Datasource by appending the structure in the extract structure and then wrote a code in respective includes ie., EXIT_SAPLRSAP_001, 002, 003, 004, it is succeeded. But when i am enhancing the LO datasource, i followed the same as above ie., append structure in extract structure and then code in respective includes. But it is not working( not showing the newly added fields in RSA3).
So, what my doubt is, is there any differences in enhancing the LO and LIS Datasources, please help me in this regard.
