Wrong text in ADRC and LFA1 table after Unicode conversion

Question

Hello,
We are doing MDMP to Unicode on SAP 4.7 system.
In post unicode activities,we had corrected the garbage characters in
table ADRC
by converting to target langauage ZH using SUMG t-code.
Condition used for addind table ADRC in SUMG is LANGU ='1' and
LANGU_CREA = 'EN'
But after converting and saving the data,most of the records have
incorrect character in word.
and text field of search term/company name/city in table LFA1 are also
wrong in correspond field in table ADRC.
Thanks

Hi Harshavardhan,
Assumption: You have Chinese entries in table ADRC with ADRC-LANGU_CREA = EN
Now you have to distinguish two problems:
1) Chinese texts are stored in ADRC fields, which are NOT used for search help texts (most of the fields - e.g. ADRC-NAME1):
These texts can be handled in two ways:
a) Change LANGU_CREA = EN to LANGU_CREA = ZH for these entries (e.g. where ADRC-COUNTRY = CN) before the Unicode conversion (by the way, I would not use ADRC-LANGU, since this is the communication language, which does not necessarily comply with the code page of the entry).
This needs to be done in a similar way as shown in z-reports described in  SAP Note 634839 ( although this specific fool-the-system case is not covered there - you have to adapt those examples)
b) Use SUMG to repair the entries using language ZH (as you already did)  
My favourite would be a), as this can be done before the conversion (Note that SUMG ineeds to be executed during downtime !)
2) Chinese texts are stored in ADRC fields, which are used for search help texts (e.g. ADRC-MC_NAME1):
a) If these entries were inserted / changed with logon language ZH, then point 1) applies
b) If users logged on with logon language EN and created the entries, then most of these texts are destroyed already in Non-Unicode system. Then there is no automatic repair possible (at least point 1 does not work). Here my statement from before is valid:
Those entries need to be generated again - e.g. if you do a dummy change on the name.
According to my knowledge, this is a manual effort (either before or after the conversion) - but maybe it can be automized ...
