Regarding making hyperlink in OOPs ALV

Former Member — Mon, 06 Aug 2007 10:45:27 GMT

Please see the following ALV Code. Its based on OOPs. There is no fieldcatalog defined in the program. In the output I want to make a hotspot on the filed VBELN & want to call T.code VA03 using SET PARAMETER ID. Please help. If I would have made it through Function Modules, It could have been easier as I can modify the fieldcatalog. Please help me urgently. Points will be rewarded.
