K2 blackpearl error with sharepoint groups
Problem:
If i change the sharepoint group users still email is going to old user.
But task is assigned to new user.
Solution:
Please check k2hostserver database.
Task will assign based on sharepoint group.
Email will assign based on the data in K2hostserver database.
Tables:dbo.groups
dbo.groupusers
dbo.users2
Email will go based on the mapped users in dbo.groupusers
dbo.Groups= GroupID,groupName(Name of the group which is assigned as destination in k2 workflow)
dbo.Groupusers=groupID,UserId
dbo.Users2=UserId,UserName, Properties
dbo.Groupusers table k2 is not updating the group users when sharepoint admini changes the users in sharepoint group.
Because of this reason email is going to old user, and task is assigned to new user.
