Service Management – Maintain Control Keys

Today we start getting into more of details of actually processing the service order.  The control keys are assigned to each operation within service order.  Now, most of the options are pretty self explanatory, but understanding the options are available is what I really want to show. 


Here’s the location within SPRO.  Notice it’s inside of the control key folder


Next up, you need to select the control key (or create a new one).  I’m going to focus on the 3 standard control keys for service management.  SM01, SM02  SM03


I’m going to start with explaining the different parameters, and then I’ll show you the other two control keys.

Under the parameters, the check mark will signify if the operation is valid for each of the different options:


Det. Capacity Requirements



Print Time tic.

By default, all the options are selected, but if you have certain operations that should be excluded from certain functions, say scheduling, then either select an existing control, your copy the closest one to what you want, and make some changes (being the SAP purest, I encourage option 2).

Next up is the confirmation:  Here’s the options to determine if you want these operations to be confirmed.

1    Milestone confirmation (not PS/PM)

2    Confirmation required

3    Confirmation not possible

    Confirmation possible but not necessary

Next up, you can determine if the confirmation should be printed.

The final piece is about external processing.  This would be used whenever you would look to a third party to execute the operation.  You can select internal, external or either.

The last 2 checkbox:

Service – determines if you can plan the service to be done.

Schedule External Operation – determines if you should try to use SAP to perform the scheduling of the external operation.

The last button is the Call up long text. So far, I’ve been unable to determine exactly what this does.  It’s possible this only has a function in production orders, and is not yet part of the service order.  If anyone knows for sure, I’d love to find out.


This is the default view for Service External (standard SM02).  Notice how few check boxes have been selected because this operation isn’t processed in-house.


And this is SM03, for external services.  By default, this one allows planning of the service.
