Unicode issueAssigning database table data to a string field of a structure

Question

Hi All,
This is piece of code where it is throwing the error in ERP 6.0 but this is working fine in SAP 4.6c.
select * into datatab-data from catsdb
where pernr IN select_pernr.
datatab-pernr = datatab-data+3(8).
datatab-tabname = 'CATSDB'.
datatab-dtype = 'C'.
where CATSDB is transparent table with 108 fields.
and datatab is a structure of type ZHCLONE_DATATAB in a Function Module defined with 4 fields PERNR,DTYPE,TABNAME,DATA.
data is a charater field of length 4999.
Error:CATSDB and DATATAB-DATA are not mutually convertable in unicode conversion.
Any pointers to this would be highly appreciated.
Thanks in advance.
Regards,
Rizwana.

Answer 1

Hi,
The Data in the table CATSDB cannot be copied directly into the field datatab-data if the catsdb contains any non-character type fields.
1>First take a work area
wa_catsdb like line of catsdb
2>Select the data from catstab into the the workarea
select * into wa_catstab from catsdb
where pernr IN select_pernr.
3>Now transform the workarea into the datatab-data variable
If the catstab contains complete character fields we can use direct move statement,else we need to use following method
class cl_abap_char_utilities definition load.
    CALL METHOD cl_abap_container_utilities=>read_container_c
  EXPORTING
    im_container               = wa_catstab
  IMPORTING
    ex_value           = datatab-data
  EXCEPTIONS
    illegal_parameter_type = 1
    OTHERS                 = 2.
