 Hi All ,

While creating the Requisitions in the iprocurement , I have to attach the attachments to the requisition .

In the Add Attachment Screen (as shown in the attachment)  , the reis one field called CATEGORY .

In the CATEGORY field , there is list of Values . " Internal To Requisitions , Miscellaneous , To Approver , To Buyer , To Receiver , To Supplier " .

In my screen the default value is pointed to the  "  Internal To Requisitions "  . But here I want to make the  " Miscellaneous " as the default value for the category field .
