Hi Mikhail,
The issue is resolved.
solution . -- very simple
tcode sxms_admi_ind
you will see the Index id with source SID
Provide OK code as SAPXI and then enter
this will enable edit mode -> edit (F5) --> chave status Active to inactive --> Save
now existing Index ID will get deleted and you should able to see blank.
now you reactivte and save --> this will create new Index id with correct Target SID
