servers' processing time depends on entity assigned time state variable

[P.Ottevanger]

Dear All,

New to Simio and struggling with the following problem.

I would like to model an entity to exit a server at its assigned time as a state variable

for now, I know this: 

Every entity is assigned before exiting the source with a state variable (pick-up time): TimeNow + random value between 1 -5

I want to use this state variable to decide with an add-on process if the server can finish processing;  TimeNow == pick-up time

if not, the server keeps processing.

In other words, the processing time of the server depends on the state variable of each individual entity. 

Hope someone has tips or tricks to solve this!

Dear All,
I used a storage queue to park the entity and used a search step to search the entities for whom the timenow == pick-up time.
These entities are pulled out of the storage queue. 
If anyone has better or easier solutions, let me know.
