the versions are:
after searching on support site:
i found the table ap_duplicate_vendors_all contains records with process_flag=N.
if we delete these records from this table, the forms starts working.
but the problem, it works only for 3-4 times and again the table gets records with process_flag=N.
If again deleted, it works.
does that mean, we have to keep on deleting those records.
or we can have any other solution.
