The pdm_export_mgr.exe process failed because stored query had an incorrect parameter for the form being exported or used. The parameters name multiple ticket types, such as cr, in, or pr, all in the same export function, which will not work.
Modify the where clause of the stored query used so it only has the correspondent object used by the form.
1. Log in Service Desk with an administrator account.
2. Go to the Administrator tab->Service Desk->Application Data->Stored Queries
3. Search the stored query used by the form and edit the where clause as mentioned.
4. Save the stored query and the issue should not occur again.
See Additional information section for further details about the store query syntax.
Please see KB Article 25395 for more information on stored query support for ticket types.
