Peoplesoft 9.1 - Time and Labor: Dynamic Groups are dead, long live Dynamic Groups!

The pronouncement of the title does not hint that Oracle has taken away the definition of Dynamic and Static groups from Time and Labor, but it's significance is greatly reduced with the introduction of approval workflow engine in 9.1 and by the improved row level security framework in 8.9. In pre-8.9 days, the entire row level security in T&L used to be driven by Dynamic Groups and it used to be a design nightmare to arrive at the best security strategy as various modules drove security differently (at that point of time, frankly dynamic groups offered a pretty flexible way of driving security as it's design is distantly similar to the current robust row level security structure). But with the introduction of the very flexible and configurable row level security structure in 8.9, the need to use Dynamic Groups for row security in T&L, almost died down and now with the introduction of the AWE framework in 9.1 - I really do not see any more need to use Dynamic Groups for security purposes. This is more a message for current 8.9 and 9.0 Time and Labor implementations - you should discourage the use of T&L security driven by Dynamic Groups as much as possible and adopt the HRMS Row Level security in Time and Labor. The focus of Oracle has been towards adopting common frameworks across various modules for driving aspects like Security, Approval, Delegation etc. and it will be great to keep that point in mind while designing solutions in these areas if you are on versions lower than 9.1/9.0.

So do we need Dynamic Groups anymore in Time and Labor?
There are two areas where the use of Dynamic Groups are significant:

1. As a parameter for running the Time Administration process. Dynamic Groups will still remain to be a very useful run control parameter for running the time administration process.

2. Grouping approvers together for use in some of the T&L specific AWE definition Ids. This is a change introduced in version 9.1 in the definition of a dynamic group. A new field called 'TL Approval Group' has been introduced in 9.1 as shown below:

When a Dynamic/Static group is selected as a 'TL Approval Group' - it will be used only as a group of potential approvers and not for row security. Row Level security cannot be attached to these groups and they can be used in the AWE Definition Ids for Time and Labor to specify the user list that approves time.

Hi Jiju,
Excellent Blog.

It's fairly apparent that organizations that were very dependent on TL Security will have to drastically re-design. What is Oracle recommending for those clients that do not follow any of the delivered Definition ID's and want to have the same security their had before. A very common theme is a group of managers have access to a group of employees (not defined by reports to, sup id, dept manager, etc).
