Mapping Line type Data to table data

Question

Hi,
I am trying to refer to a data element present in the line type of a table type which belongs to an import parameter of a smartform. How will i access the data element to use in the where clause of a select statement.
For Eg:
Import Parameter name: PARTNER_H
TYPE: CRMT_OUTPUT_PARTNER_H_COMT  (table type)
The line type attached to this table type is CRMT_OUTPUT_PARTNER_H_COM.
This line type is the structure that contains the data element that i need to use. the details are as below:
Component: RELATION_PARTNER
Component type: BU_PARTNER_GUID
I have written a select statement as below:
SELECT SINGLE * from BUT000 into I_FS_BUT000 where
  PARTNER_GUID = PARTNER_H-RELATION_H.
I have given the input parameter as  PARTNER_H.
It throws me an error that "PARTNER_H" is a table without a header line and therefore has no component called "RELATION_H".
Is this the correct way to access the data element?Please help.

Hi Neena,
               Since PARTNER_H is an internal table it may have multiple values. If you want only a single entry from BUT000, you ll have to determine which entry from PARTNER_H you need in select query.
If it is always going to have only a single value then , this will work :
data: wa_partner_h type line of CRMT_OUTPUT_PARTNER_H_COMT.
Read table partner_h into wa_partner_h index 1.
if sy-subrc is initial.
SELECT SINGLE * from BUT000 into I_FS_BUT000 where
PARTNER_GUID = WA_PARTNER_H-RELATION_H.
endif.
