Purchase Order guidance

[Janniffer Mukantale <jm...@hotmail.com>]

Hi every body,
Iam new to ofbiz,  i was able to set it up on a central server and POS machines which are syncing using the PUSH mechanism when i sell an item. 
 Note: My organizational structure is; 
there are two selling points. 
the selling points requests for items for selling from the central storeAnd the central store makes the purchase order from the external suppliers.
Issue:  The problem cames when i want to replenish the selling points inventory.
 I tried by placing a purchase order but when i receive the the central server's inventory level remain unchanged.When i place an order from the selling localhost order manager it takes long to reach the central server.when i receive from the central server the selling points database is never affected.

Request:
can some body guide on how i can receive a purchase order against 
product store or how best can i make item request to affect the 
inventory level of another store/central server.

I will be very happy upon receiving your help.

Jannie
