H Sarada,
I am also having the same requirement populating Notes details latest change date to a custom field attributes.
I tried implementing the BADI SCMG_CHNG_BFR_STR_C and not able to get the notes details while triggering this BADI/inside this BADI.
This BADI is triggering twice while Saving the Case ID and able to see the CLASS for the notes inside internal table 'G_TAB_SUBCOMPONENTS' but not able to get the notes details/notes log details during this BADI triggering.
Please let me know how to make use of this CLASS details related to Notes and help me out how you solve this issue/requirement.
Thanks
Kishore
