Creating RFC to Display HR data
Need some advice here. First time doing ABAP. I'm developing a JAVA webdynpro and need to create RFC to get data from ECC and display it back in my application. My input parameter would be the 'SY-UNAME' (SSO enabled. therefore, portal and ECC have the same ID). This value would be crossed check in infotype 0105 to get the personnel No. we will the use this personnel number to get data from other infotype. I need to get this data out to the portal.
Is there any pointers on how and where i should begin? Thanks
