Hi all,

Could someone let me know what I am getting this error. How could I solve it? Any ideas are highly appreciated.

    requires that the operands "dst" and "src" are convertible.             
    Since this statement is in a Unicode program, the special conversion

    In this case, these rules were violated.

Hi Mr. Wong,

Hopefully you you have to point both "src & dst" to one type of Fileld/Domain.

Please check that once.

Thanks & regards,

Hello,

This is because you're trying to move a data of TYPE CDTABKEY(CHAR70) to a structure TYPE EKBN. Try to change the data declaration as follows & the code should work:

DATA: lv_fieldname  TYPE        fieldname.
DATA: lv_tabkey     TYPE        ebkn.

You can read more about the data conversion rules in UC environment on F1 help.
