Hello Maciej Swiderski,
Thanks for your kind reply. Which implmentation regarding metada will be more useful when perfomance is concern,
1) Store metadata into process instance and reterive when we require.
2) Use user defined entity of metadata and get by using database join table with process instance.
As we are storing object into process instance and i am affarid regarding performance issue. Please advise and thanks for help again.
Regards,
