Question

Hi Experts,
please check my code below
DATA: BEGIN OF ibsis OCCURS 100, 
         ebeln LIKE bseg-ebeln,   
         ebelp LIKE bseg-ebelp,   
         bsis LIKE bsis,          
         ldgrp TYPE fagl_ldgrp.   
DATA: END OF ibsis.              
TYPES : BEGIN OF TY_ZFINITEMCAT,
               pstyv TYPE vbap-pstyv,
             END OF TY_ZFINITEMCAT.
DATA : GT_ZFINITEMCAT TYPE STANDARD TABLE OF TY_ZFINITEMCAT.
FIELD-SYMBOLS : <fs_ZFINITEMCAT> TYPE TY_ZFINITEMCAT.
DATA: l_item_catecory TYPE pstyv.
SELECT VALFROM
          INTO TABLE GT_ZFINITEMCAT
          FROM SETLEAF
          WHERE SETNAME EQ 'ZFIN_ITEMCAT'.
LOOP AT ct_ibsis[] ASSIGNING <ibsis>.
"Check if we can find one item of the wrong category, if so then we remove the documents.
     SELECT SINGLE pstyv INTO l_item_catecory
       FROM vbap
       WHERE vbeln = <ibsis>-bsis-zuonr
         AND pstyv NOT IN GT_ZFINITEMCAT.  "getting error here (The line structure of the table "GT_ZFINITEMCAT" is incorrect.)
     IF sy-subrc = 0.
       DELETE ct_ibsis[] WHERE bsis-zuonr = <ibsis>-bsis-zuonr.
     ENDIF.

When using IN you must use a range table afterwards.
Try this :
DATA: BEGIN OF ibsis OCCURS 100,
         ebeln LIKE bseg-ebeln,  
         ebelp LIKE bseg-ebelp,  
         bsis LIKE bsis,         
         ldgrp TYPE fagl_ldgrp.  
DATA: END OF ibsis.             
DATA: gt_zfinitemcat type range of vbap-pstyv,
FIELD-SYMBOLS : <fs_ZFINITEMCAT&gt; TYPE any.
DATA: l_item_catecory TYPE pstyv.
SELECT VALFROM AS LOW
          INTO CORRESPONDING FIELDS OF TABLE GT_ZFINITEMCAT
          FROM SETLEAF
          WHERE SETNAME EQ 'ZFIN_ITEMCAT'.
LOOP AT GT_ZFINITEMCAT ASSIGNING <fs_ZFINITEMCAT>.
     <fs_ZFINITEMCAT>-SIGN       = 'I'.
     <fs_ZFINITEMCAT>-OPTION = 'EQ'.
ENDLOOP.
LOOP AT ct_ibsis[] ASSIGNING <ibsis&gt;.
"Check if we can find one item of the wrong category, if so then we remove the documents.
     SELECT SINGLE pstyv INTO l_item_catecory
       FROM vbap
       WHERE vbeln = <ibsis&gt;-bsis-zuonr
         AND pstyv NOT IN GT_ZFINITEMCAT.  "getting error here (The line structure of the table "GT_ZFINITEMCAT" is incorrect.)
     IF sy-subrc = 0.
       DELETE ct_ibsis[] WHERE bsis-zuonr = <ibsis&gt;-bsis-zuonr.
     ENDIF.
   ENDLOOP.
