What you are calling "4 different IRP Types" would need to be defined in IRP as four different Report Settings.  In Task Scheduler, on Tab 1 Schedule, define a REPORTS Task and on the Tasks Tab 2, choose Module = I/P; Task = Inventory Requirement Planning and Report Setting = your custom report setting previously defined. 

Under the module selection I am missing I/P. IRP is enabled on sage. is there anywhere where this can be enabled in task scheduler?

IRP wasn't added to Task Scheduler until v2023.

We are on version 2023

Ive found the fix. Disregard
