• Unable to create/change an external operation with an Outline Agreement in Maintenance Order in the operations tab.

SAP S/4HANA Cloud Public Edition

1. Access app Change Maintenance Order.
2. Input Order number.
3. Navigate to Operations Tab.
4. Select an operation item.
5. Input an Agreement Number.
6. Press Enter.

Requirement needs to plan maintenance work using external labor under an outline agreement. The outline agreement is for a service product, but external operations generally do not carry a material number. The observed behavior is therefore expected.

In SAP S/4HANA Cloud Public Edition, there are two possibilities for procuring external labor:

1. Using a control key such as YBM2 which indicates that an operation is processed externally. No material number is used for such procurement. 
2. Using a material of type SERV.

Given the material number is already a service, YBM2 control key would not be used but instead use YBM1 and add the service material in the sub-screen "Services". For more information about the handling of service materials, please also refer to SAP Help:
