i have sequence diagram in enterprise architect.

in process can initiated 1 of 2 sources: either timer process or manual 1 (a user hitting button on gui screen).

how show on diagram, please?

a sequence diagram not allow show 2 alternative invocations of same operation. accomplish in activity diagram using 2 different receive events leading same activity, in sequence diagram can't draw 2 messages same sequence.

what can phone call other sequences within sequence.

you first drawing sequence process, not showing how initiated or whom happens within process.

you draw 2 separate sequence diagrams 2 different cases, , each drag first sequence diagram , drop "interaction occurrence."

finally, draw message actor interaction occurrence. occurrence can double-clicked in diagram, opens sequence diagram describing process.

a related problem is, of course, there no standard way of showing spontaneous occurrences (timeouts) in sequence diagrams, since focus on interaction between caller , callee (often in cascade). simplest way of dealing create actor "clock" or similar, , have initiate process.
