Hi Alwina,
I've looked into the tranactional audit logs and ST03 for both DDIC and the basis user ID who reported resolving the issue (see attached screen shots). The only transactions that look promising are SWU3 (Worklfow Runtime customizing)and SWU4 (Workflow task consistency checks). While it is possible one of these starts some synchronization process, I couldn't find anything like that explicitly in either transaction. By the way, these two transactions would fall into the window of time the issue was resolved.
I am not familiar with the entry (in attached screen shot) for <AD_NTAB_SYNC>. Nor could I determine the time this was done which is probably due to a lack of understanding on my part as to what this entry represents.
Thanks for all your support. I appreciate the time you have taken to assist me in unravelling this mystery.
Kindest Regards,
KM
