Language issue for downloaded product category

When you try to edit some downloaded product categories, you may meet with this error message:

The root cause is for example ERP supports language A and B, and CRM only supports A.

After you perform customizing download, description in language both A and B will be downloaded to CRM. And description in B looks like below in CRM, not valid!

# Solution 1

Remove description B in ERP, and then do customizing download again.

# Solution 2

If you are working on CRM dev system, execute the following ABAP code to remove category description with invalid language:

method REMOVE_INVALID_LANGUAGE.
    DATA: lt_cate_text TYPE STANDARD TABLE OF COMM_CATEGORYT,
          lt_delete LIKE lt_cate_text,
          LT_SEL type SEL_OBJT.
    data(ls_sel) = value SEL_WBTYPE( sign = 'I' option = 'EQ'  ).

    DATA(LV) = '1234567890ABCEDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.
    DATA(lv_length) = strlen( lv ).
    DO lv_length TIMES.
      data(lv_offset) = sy-index - 1.
      ls_sel-low = lv+lv_offset(1).
      APPEND ls_sel TO lt_sel.
    ENDDO.
    SELECT * INTO TABLE lt_cate_text FROM COMM_CATEGORYT where langu not in lt_sel.

*    LOOP AT lt_cate_text ASSIGNING FIELD-SYMBOL().
*      CALL METHOD cl_com_product_basic=>t002_read_single
*      EXPORTING
*        iv_spras  = -langu
*      EXCEPTIONS
*        not_found = 1
*        no_desc   = 2.
*
*      IF sy-subrc = 1.
*         APPEND  TO lt_cate_text.
*      ENDIF.
*    ENDLOOP.

    WRITE: 'total invalid language text deleted:' , lines( lt_cate_text ).

    If iv_prod_mode = abap_true.
       DELETE COMM_CATEGORYT FROM TABLE lt_cate_text.
       COMMIT WORK AND WAIT.
       WRITE:/ 'delete successful' COLOR COL_POSITIVE.
    ENDIF.
  endmethod.

After that you can edit downloaded category as usual:
