**Please note:** The term BHP is an abbreviation for the german word: "Behandlungspflege". These are the measures which have been prescribed by a GP and assigned to the responsibility of the nursery staff. Applying medication is one of those measures, for instance.
</alert>

This Panel is handling the BHPs for the daily access by the nursery staff. The user can apply, refuse, refuse (with discarding the medication), undo the several BHPs presented.

==== isChangeable() ====

Besides the ACLs there are further professional reasons to allow or prevent the access to the BHPs. To tell if a BHP may be changed, it is vital to consider the state of the BHPs and some other issues.

There is one method that has a very important role in the authorization chain: ''BHPTools.isChangeable(BHP bhp)''. **This method is only useful for BHPs, that are not open anymore.**

It returns ''true'' (hence empowering the user to change the BHP) when the following conditions are satisfied:
  * the time (in minutes) between confirming (apply) the BHP and **now** doesn't exceed ''SYSPropsTools.BHP_MAX_MINUTES_TO_WITHDRAW'', which is currently hardcoded in the connected database table ''sysprops''.
  * the underlying prescription is not **closed**
  * this BHP must not be **open**, and the **user trying to change it now, is the same one who confirmed it** in the first place.
  * the resident is **active** in the system and **not currently absent**
  * if there is medication involved, there must not be any trouble with it. meaning:
    * if the medication's stocks should be calculated, the there must be an **accessable stock** in use.
    * it is way to complex to undo withdrawals for more than one stock((which can happen if a stock is emptied during the cause of the confirming the BHP and a new stock is opened and used automatically)). Therefore the user **CANNOT** undo them.

==== Confirming, refusing or discarding an open BHP ====

the user can apply, refuse or refuse (discard) a BHP if:
  * it is still **open** (of course)
  * the underlying prescription is not **closed**
  * the method ''BHPTools.isChangeable(BHP bhp)'' returns ''true''.

==== undoing a confirmed BHP ====

a user can reset a BHP to the **open** state if:
  * it is **NOT open**
  * the underlying prescription is not **closed**
  * the method ''BHPTools.isChangeable(BHP bhp)'' returns ''true''.
