Problem about casting in internal tables

Question

Hello,
TYPES:
  BEGIN OF ts_matnr,
    matnr TYPE matnr,
    objct TYPE cuobj,
  END   OF ts_matnr.
  tables: mara.
DATA:
  myStatus(20) type c,
  mySTANDARDCLASS(20) type c,
  gt_matnr TYPE STANDARD TABLE OF ts_matnr WITH DEFAULT KEY,
  gs_matnr LIKE LINE OF gt_matnr,
  gs_mara  TYPE mara.
SELECT-OPTIONS:
  pr_matnr FOR gs_mara-matnr.
START-OF-SELECTION.
SELECT matnr
       matnr AS objct
       FROM mara
       INTO CORRESPONDING FIELDS OF TABLE gt_matnr WHERE matnr IN pr_matnr.
I want to write both the normal String and the value as object  into the table. But there is a error at the select saying the fields can't be converted to target field.
I don't know what the problem is. Can you see it?

Answer 1

unfortunately, I just saw that I just walked around my problem instead of solving it. The reason I want to have this MATNR is that I need to use it as Objectkey for a BAPI call:
LOOP AT gt_matnr INTO gs_matnr.
CALL FUNCTION 'BAPI_OBJCL_GETDETAIL_KEY'
  EXPORTING
*    CLOBJECTKEY           = gt_matnr-objct "nicht Tabelle, sondern Arbeitsbereich
    CLOBJECTKEY           = gs_matnr-objct "hat Typ OBJCT <=> BAPI1003_KEY-OBJECT_GUID
    CLASSNUM              = 'FARBIGE_UNTERLAGEN'
*   KEYDATE               = SY-DATUM
*   LANGUAGE              = SY-LANGU
IMPORTING
   STATUS                = myStatus
   STANDARDCLASS         = mySTANDARDCLASS.
*  TABLES
*    ALLOCVALUESNUM        =
*    ALLOCVALUESCHAR       =
*    ALLOCVALUESCURR       =
*    RETURN                =.
ENDLOOP.
But with the type from Shiva's code the debugger says that the given parameter has a wrong type.I just can't get this BAPI to work. I want to use it to get the classification information about a material.
