How to configure more than 3 activity predecessor for another activity

In Flexsim HC I want to add an activity called "Revaloración" that means that the patient must be examed by a doctor after finish other activities that are being consider in a decision point. The problem is that the logical secuence of activitys in real life is:

- 70% of the patients must complete this activities "160_RetornoObs" and " 192_Analisislab" for doing "200_Revaloracion"

- 30% of the patients must complete this activity "170_Obsx" for doing "200_Revaloracion". (I created 170 like a no process activity, cause those patients no receive any treatment)

According with the configuration did in the decision point (activity 90), I don´t now how to configure the predecessors activities in "revaloration" in orden to comply with the both conditions describe before.

PD: All the patients must pass and complete this other activities : "130_Aplicarmendicamento" and "180_Observacion".

I attach the flexsim model in orden you can visualize what i'm traying to explain. Thanks a lot. fase-6-img-ok.fsm.

For activity 200_Revaloracion it looks like you just need to set the Predecessor to be:

160 OR 170

since these are the last activities in each route.

I noticed a couple little errors you'll want to clean up though:

170_Obsx has its predecessor set to 160. I think you want to uncheck the Use Predecessors checkbox

150_Imagenologia - I think you want to change its predecessor from 191 to 192
