Item category Issue

Hello,

I am trying to create an Sales Order thru an Inbouind IDOC.

But I am getting an error message " No Item Categiory available (Table T184 ZTFT TEXT)" there is no such group called as TEXT .

All the other setting in VOV4 are properly maintained,

Kindly let me know the solution as I am able to create the Sales Order manulally fior the same data.
