1. Unset estimated Begin of the insertiontimes areEnd of the insertion Begin of the deletion time &quot;-&quot; is currently (12.1) included into the calculation with 8 h. It is almost impossible for users to understand this assumption. It is alsoEnd of the deletion not Begin of the insertionconsidered asEnd of the insertion Begin of the deletion documented. 
**Example 1**: The estimated time of _Grandchild 1.1.2_ isEnd of the deletion 0 h. Begin of the deletion The algorithm therefore implicitly assumes an estimated time of 8 h. This leads to a Progress % for Child 1.1 of 50 %. Since the estimated time for _Grandchild 1.1.2_ is &quot;0&quot; it must not be included into the progress calculation of Child 1.1.End of the deletion
2. It is not possible to set a percentage % for Begin of the insertionthe estimated time that is defined forEnd of the insertion a parent work package.
**Example 2**: The estimated time for Child 1.1 itself is 24 h. It is not possible to define Progress % for those 24 h. The shown 50 % is derived from the _Grandchildren 1.1.1_ and _Grandchildren 1.1.2_.

* For the estimated time field it is possible to understand whether a value is empty (not set) or set to 0 h. This allows to better understand if an estimate has been made or not.
* Unset estimated time is included by 0 h into the Begin of the insertioncalculation.End of the insertion Begin of the deletion calculation (not 8 h).End of the deletion
* It is possible to set the Progress % for the estimated time of Begin of the insertionaEnd of the insertion parent work packages.
* The Progress % value Begin of the deletion calculatedEnd of the deletion for Begin of the insertiona work package has two values:
* The Progress % for the estimated time of the parent work package itself.
* The Total Progress % that als includes allEnd of the insertion children work Begin of the insertionpackages.
* When filtering child workEnd of the insertion packages Begin of the insertionfrom the list the value in the bracket remains unchanged. The percentage % for the filtered work packages only includes the values of the filtered work packages. It does not include the values from children values whichEnd of the insertion are Begin of the insertionfiltered out.
* The Progress % of a version is the same as the total progress when filtering for all work packagesEnd of the insertion Begin of the deletion indicatedEnd of the deletion in Begin of the insertionthis version. It also does not include children work packages from other versions.
* Optional: for parent work packages that have a children work package with unsetEnd of the insertion Begin of the deletion brackets (similar toEnd of the deletion estimated Begin of the insertiontime there is an indicator in the hierarchy sum icon.End of the insertion Begin of the deletion time).End of the deletion

## Alternative concepts

Work packages that has children get their estimated time automatically calculated from this ones and can&#39;t have an own estimate. Adding a subtask deletes the values entered for the summary task.
