FLC administrators most often require to run specific clean up activities on whole bunch of items in a workspace. For example, i needed to run script (which is registered as an external script on items in Items & BOMs workspace) to set a group as an additional owners to open up access to that group. This activity required DMSIDs of bunch of items which meet the criteria to trigger an external script registered on items through a power shell script. The power shell script has a feature to process specific items given their DMSIDs.
If there would have been a feature to extract DMSIDs of bunch of items through Reports, my job would have been easy. As a workaround to this problem i implemented an external script with required conditions to get to the applicable items by inputting DMSIDs of all items or released items. This process is really time consuming. I have been told by the Autodesk consultants to adopt to this workaround because finding an item by DMSID is quicker than finding an item by its properties such as Number, Name, Release Letter, etc. is time consuming.
