One of the most complicated activities for WebDynpro ABAP newbie and one of the most boring activities for expert developer is the customization of ALV.
Activities are really simple if you know Abap OO but very repetitive, you have always to code pretty the same piece of code.
So here is the SALV Generator, the first tool for the creation of ALVs in WDA in just a few steps and with no coding required

Any feedback is really appreciated. Post yours on SDN.
