Requirements reappear in Sourcing Cockpit - Urgent

Hi,

Suddenly our users reported that requirements from MRP which were sourced long back reappeared in sourcing cockpit today (When you do Find). Most of the items are 0 qty and greyed out but some are non-zero qty but they too were sourced long back.

I am thinking of clearing these already sourced requirement using BBP_GET_STATUS_2. There were no notes applied in the last week. Until 2 days back the SOCO was in good shape (according to one of the users).

Any body experienced anything of this nature and how they solved it?
