Hi Chris , if I undertood your needs.
When you want transfer Statuses to User Status in Operation order when planning (MRS) is save, you can assign the follow statuses in Demand Item in MRS Configuration:
PLAN_FULL .- If the resource works on the demand for a duration equal to the complete duration of the demand the abstract status
PLAN_UNDR .- If the resource works on the demand for a duration lesser than the complete duration of the demand the abstract status
PLAN_OVER .- If the resource works on the demand for a duration more than the complete duration of the demand the abstract status
And when you need assign in Header Order, you can assign the follow status in Demand Header in MRS Confg.:
OR_HAS_ASG Order Contains At Least One Assignment
You can do that in MRS Customizing:
/N/MRSS/IMG >> SAP Multiresource Scheduling >> Basic Settings >> Assign Objects >> Status >> Assign Status for Demands (ERP)
In this Customizing activity, you assign concrete ERP statuses to the abstract statuses that are used for resource planning in MRS.
