Thanks for the link. I am familiar with this one as this question was asked by a friend of mine long time back. I do know that the standard field is of 300 characters. But the issue is even if I add a custom field of say 1000 characters to the append structure in CRM_ISU_SRV_ORDER_CREATE and create a text area for it in IC Web. It still takes in just 255 characters. Hope you understood my question!
