Learn how activity and service call properties in SAP FSM are mapped with service order operation/service order data in SAP ECC/S4:

Activity

SAP → FSM

FSM property	Source in SAP ECC/S4
Planned start date	If ‘DT Order Header’ set in transaction /PACG/ECM_SCTD, basic dates from service order header are used. Otherwise, operation constraints are used. If constraints cannot be found, field ‘Assignment date/time’ from /PACG/ECM_SCTD determines the date source. Early – use earliest scheduled start date/time Late – use latest scheduled start date/time Early and late – use earliest scheduled start date/time
Planned end date	If field ‘DT Order Header’ is set in transaction /PACG/ECM_SCTD, basic dates from service order header are used. Otherwise, operation constraints are used. If constraints cannot be found, field ‘Assignment date/time’ from /PACG/ECM_SCTD determines the date source. Early – use earliest scheduled finish date/time Late – use latest scheduled finish date/time Early and late – use latest scheduled finish date/time
Duration	Operation duration
Planned duration	Operation’s work
Earliest start date	Based on setting ‘Dates alloc’ in transaction /PACG/ECM_SCTD: B - basic dates - Basic start date from Service Order Header S (space, default value) - scheduled dates – use earliest scheduled start date from the operation
Due date	Based on setting ‘Dates alloc’ in transaction /PACG/ECM_SCTD: B - basic dates, use service order header basic finish date S (space, default value) - scheduled dates – use latest scheduled finish date from operation

FSM property	Target in SAP ECC/S4
Planned start	Operation constraint start date (Earliest start/Latest start also updated)
Planned end	Operation constraint finish date (Earliest finish/latest finish also updated)
Duration	Duration updated only if ‘No work/dur’ not set in transaction /PACG/ECM_SCTD; Operation duration normal
Planned duration	Operation work activity
Earliest start date	No impact
Due date	No impact

FSM property	Source in SAP ECC/S4
Start date	Based on setting ‘Dates alloc’ in transaction /PACG/ECM_SCTD: B - basic dates - Bsc start from Service Call Header is used: S (space, default value) - scheduled dates - the Earl start from the earliest operation is set as Start date:
End date	Based on setting ‘Dates alloc’ in transaction /PACG/ECM_SCTD: B - basic dates - Basic fin. from Service Call Header is used S (space, default value) - Latest fin from the last operation is used.
Due date	Use the finish date from service order header:

FSM property	Target in SAP ECC/S4
Start date	Service order headed basic start
End date	Service order headed basic finish, but only if the due date was not maintained in FSM
Due date	Service order headed basic finish - priority over end date if both were maintained in FSM
