Activity diagram question

[panda72]

Hi.

I am new to these forums and to SysML, but I hope some of you can help
me answer my question.

I have created an activity diagram (using RSA with EmbeddedPlus' SysML
ToolKit) which describes a block's operation, let's call it moveTo
(p:Position). Position is an enumeration describing two different
positions. This activity (used as a call behaviour action in a
containing activity diagram) has an activity parameter node describing
the parameter in the operation.

Is there a way I can specify the value of the parameter sent into the
parameter node from the containing activity diagram?

Inside the activity I check the value of p to decide on a set of
following actions later on in the control flow.

The activity is being used by two different higher level activities,
each where I wish to specify 2 different values of p.

My other solution is to not specify the operation as it is, and give
up on reusing the activity and rather make two separate activities
moveToPosition1 and moveToPosition2.

As I am new to this, I am a bit unsure whether I have included enough
information for anyone outside my project to understand me.

Hopefully you can help me! Thank you for reading!
