how to change value of table property using C/AL

if any one can tell me whether it is possible to change values of table property using C/al programming and how to do that

What properties you want to change and where do you want to change. Can you please bit more clear on that. Jagjeet

thanks for your reply i want to change the table relation property value at run time.can we do that…

Sorry man you cannot change this property at runtime. But if you really want than instead of defining the table relation to the field. Why dont you write the code on the lookup trigger on the table. I hope this will fullfil your requirement. Jagjeet
