Hi gurus,

I am new to SAP CRM 2007. I have a requirement in which I need to create a view which will retreive data from my custom z table. But when you create a view , the wizard ask for Model nodes and, Bol entity, Bol relation etc. Kindly let me know what data I need to enter here so that I can relate to my custom table. I think I need to create a bol structure for my ztable. Kindly guide me in this regard.

Thanks & Regards,
