The first time, pallets get stored in rack and later on, they get picked by the resource.
Now 2nd time when pellets come to get store in the rack, I get rack full error but there is 0 pallets in rack at that time means rack is empty.
Attaching the model images below.

Pallet Rack
Rack Store
How can i solve this problem?
I suspect you didn't use a rackpick to take the pallets out of the storage... you MUST use a rackpick
Or you need to use palletRack.remove(agent);
If that's not the problem, then you will have give more information

i would like to pick a certain amount of pallets from my racks but I have no idea how to actually do that. For example, I would like to deliver 5 pallets but i have 25 stored, if i use a wait or a queue that I release all agents get picked up.
to release 5 agents from the wait block so they can be delivered you have to do the following
List <MyAgent> deliverables=findAll(waitBlock,w->true).subList(0,5);
for(MyAgent x : deliverables){
waitBlock.free(x);
}
I know that for an object to be removed from a pallet rack you need "Rack Pick". However, in one of my models, I have a different configuration where I am using pick up:
Step 1: 10 agents are in the rack
Step 2: Another agent picks them up
The way AnyLogic understands the above is that the rack still holds 10 agents, so I get the error eventually that the pallet rack is full. Is there a simple turnaround for this?
you have to remove the agents from cells with this line of code
palletRack.remove(agent);
put it to your pickup block, "on pickup" trigger.
i`m trying to take pallets from a conveyor to a Rack and after some time the Picker(Ressource) should take the Pallet out of the Rack to a conveyor again. But if i try to use the Rack Store, i get the error: The agent is not in a network. I think the problem is the Ressource(Picker), because without it the Rack Store is working.
Thanks for helping.
This might work, assuming you are using a conveyor from the material handling library, after the conveyor use a conveyorExit block.
The conveyorExit block allows your agents to move smoothly from a conveyor network to the normal network.
If you are using a conveyor from the process modeling library, then it means that you are not connecting your networks correctly and you should be sure you conveyor path is connected in the same network as the path in which your palletRack is located.
This might fix. In my case: I had 4 process flows of the same type of agent (ie. agent Type: product) coming into the RackPallet. Two is a to model processes before agent:product is stored in Rack, and the other two is to model the initial Stock of the Rack.
This solved my problme: I put the code
agent.setNetwork(network2);
before the RackStore of the initial Stock process flows, and it worked. I think this is because when we model initial Fill, the agent is not set on a on network yet.
My wait block should test if my pallet rack has enough space to store my pallets. So when I have 20 pallets and my store has space for 15, 15 should be stored and the other 5 pallets should wait in my wait block until the pallet rack has space again.
The problem is that I get an error that there are no empty cells which means that the pallets which don't have space not wait in my block but go trough the wait block and that causes an error.
Where is the problem? Wait block and rack pick are attached.

I suggest you switch to using RestrictedAreaStart and RestrictedAreaEnd blocks: Simply queue agents before and set the capacity of the restricted area to your pallet capacity.
Much easier (and less error-prone) than your manual approach.
Is it possible to move pallet between two different racks directly, without adding intermediate point node? For example I have two racks one at the receiving dock and one a the storage, after unloading all pallets to Receiving rack I need to send it to storage rack. So I understand I need to add two blocks Rack Pick and Rack store. Is it possible to combine those two?
You can always combine any number of blocks and make your own composite block. Select them, right-click and choose "create flowchart block".
This tutorial (phase 7) shows you how to do it and how to make it as flexible/reusable as you want.
