ABAP-DICTIONARY PROBLEM

Question

I have created one Z-Table with following fields
Fields                                          Data Elements
MANDT                                       MANDT
WERKS                                      WERKS_D
MATNR                                       MATNR
BWART                                      BWART
SMTP_ADDR1                            CHAR50
SMTP_ADDR2                            CHAR50
SMTP_ADDR3                            CHAR50
When I enter some data in all the fields through Table Maintainance it is not allowing me to enter data in last field. While saving it gives error  ‘Data objects in a Unicode program are not convertible.’
Please help me out.

Answer 1

Please look at the SAP Note : 551704
Reason and Prerequisites
In a unicode program certain rules apply for the
conversion between structures and single fields.
Conversion is only possible if the structure
begins with a character type group and if this group is at
least as long as the single field.
The dump indicates, that the extension table defined in
transaction /SAPTRX/TSC0ET (and linked to an event handler type
with transaction /SAPTRX/TSC0TT) was not set up according to
these rules.
Solution
Use only character-type fields (CHAR, NUMC, etc.)
and data elements pointing to character-type
domains in an extension table defined in transaction /SAPTRX/TSC0ET.
