Check sales order exits for category ZTAC

Question

Hi Experts
I have a requirement to modify the iDOC interfaced program,
In the routien which checks for the existence of a production order, I have to modify the following
1.  Inspect each item on the sales order
2. If (and only if) there is atleast one item with a category of "ZTAC" then check for a production order otherwise processing the order in the usual manner.
Could anyone tell me how to check (Is there a sales order) if no then display error message if yes then is there a production order if no display error message if yes Create confirmation .......................
I want to know how to write a coding to check sales order exits from table VBAP,VBAK Etc., .
Thanks in Advanced

Hi Prabhu
Thanks for your email and response but I need to check this in program for IDOC ....Modification
Insert code in this way
check sales order for category = 'ZTAN' inspect for each item on sales order
and if you found item with cateogry ZTAN then check for production order otherwise go asual manner
I WANT TO WRITE A CODING HERE **********************
  if production order required then check
                for each item on sales order item list
                      with item category = 'ZTAC' then
                                 return true
                            next
                              end function
  VBAP TABLE field VBELN and PSTYV (ZTAC,ZTAN Etc)
Eg of coding
if lva_saleord is initial
        select single * from vbap into l_saleord
          where vbelv = lva_saleord
          and   vbeln = lva_vbeln and
          exit.
        endselect.
      endif.
I want to write a small program in between to check the sales order exits if it is then I have to go to deliveries ...................
