3624270 - Time Collectors aren't allowed in the time recording profile if a flexible approval period is selected

In the flexible approval period time sheet UI, the following error message is displayed:
"Time collectors aren't allowed in the time recording profile if a flexible approval period is selected. The time collector group XXX is used in the following time recording profile: XXX. See the following time valuations: XXX. "
Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.  

1. In the Time Recording Profile, set the Time Recording Approval Period field "Length" as flexible approval period. 
2. Add time valuations which uses Time Collector to the Time Recording Profile.
3. Attempt to open an employee's time sheet and see the error message: "Time collectors aren't allowed in the time recording profile if a flexible approval period is selected. The time collector group XXX is used in the following time recording profile:"

This is expected system behavior. 

Time collectors cannot be set up for monthly time sheets.
Instead, please set up daily, weekly, and monthly time containers.
Time containers allow different period lengths, including a period of 1 – 12 months or a period of 1, 2, or 4 weeks.
