Must have the same type and the same length

Question

hi experts,
DELIVERY_PLANT  data type STRING    //from proxy class, can't be changed
      BEGIN OF ty_citem,
          article type matnr,
          werks   type werks,
       END OF ty_citem,
LOOP AT it_items INTO lv_item.
    lv_citem-article = lv_item-article.
    lv_citem-werks = lv_item-DELIVERY_PLANT.
    APPEND lv_citem TO GT_citem.
    clear lv_citem.
  ENDLOOP.
SELECT matnr werks
       from marc
       into table GT_marc
       for all entries in GT_citem
       where matnr = GT_citem-article  and werks = GT_citem-werks.
error message here:When you use the addition "FOR ALL ENTRIES IN itab", the fields "WERKS"
and "GIT_CITEM-WERKS" must have the same type and the same length.

Hi,
You know for statement FOR ALL ENTRIES in where clause data type and length should be match.
As per my understanding ,here GT_citem-werks is a string. But you know data type of WERKS_D is char with lencth 4.
Use the below select statement.
SELECT matnr werks
       from marc
       into table GT_marc
       for all entries in GT_citem
       where matnr = GT_citem-article  and werks = GT_citem-werks+0(4).
Thanks.
