CATS Times sheet in Workmanager

Hi Experts,

We have SMP 3.0, Work manager 6.1 and Iphone is the end device,

We successfully have the Notifications app in production and users are comfortable with that..

Now there is a requirement to add CATS Time sheet aswell.

With the Work manager 6.1 can we implement/Enable the CATS app including with Notifications? Is there any risks/constraints?

There should be workflow to route the Time sheet for approval. How to come across with the requirement.

Please suggest.

Thanks in advance..

Regards,

Thulasiram.
