-Improve payment changes when user did a mistake and disable some actions on
-Point of Sale Bank Statement Line
-
-* Add the possibility to switch a payment (account.bank.statement.line)
-  of an order from a journal to another. This feature is usefull when
-  the user realized that he did a mistake, during the close of the session,
-  or just after he marked the order as paid
-  (Only if entries has not been generated)
-
-.. figure:: https://raw.githubusercontent.com/grap/grap-odoo-incubator/8.0/pos_change_payment/static/description/pos_order_switch_payment.png
-
-* Add the possibility to change all payments (method and amount) of a POS
-  (Only if entries has not been generated)

-
-Bug Fixes / Improvement
-~~~~~~~~~~~~~~~~~~~~~~~
-
-* In the pos.payment wizard, display only the payment methods defined in
-  the current POS session
-
-* Disable the possibility to edit / delete a bank statement line on a POS
-  Order that has generated his entries, except using the wizard of this
-  module. This will prevent the generation of bad account move during
-  the close of the session; (mainly unbalanced moves)
-
-* All the cash payment are merged into a single one statement line. This
-  feature is usefull if the user use OpenERP as a calculator, writing
-  for a payment:
-
-1. Payment 1/ Cash 50 €;
-2. Payment 2/ Cash -3,56 €;
-3. With this module, the final statement line is a single line Payment 1/ Cash 46,44 €

-Improve payment changes when user did a mistake and disable some actions on
-Point of Sale Bank Statement Line
-
-* Add the possibility to switch a payment (account.bank.statement.line)
-  of an order from a journal to another. This feature is usefull when
-  the user realized that he did a mistake, during the close of the session,
-  or just after he marked the order as paid
-  (Only if entries has not been generated)
-
-.. figure:: ../static/description/pos_order_switch_payment.png
-
-* Add the possibility to change all payments (method and amount) of a POS
-  (Only if entries has not been generated)
-
-.. figure:: ../static/description/pos_order_change_payments.png
-
-Bug Fixes / Improvement
-~~~~~~~~~~~~~~~~~~~~~~~
-
-* In the pos.payment wizard, display only the payment methods defined in
-  the current POS session
-
-* Disable the possibility to edit / delete a bank statement line on a POS
-  Order that has generated his entries, except using the wizard of this
-  module. This will prevent the generation of bad account move during
-  the close of the session; (mainly unbalanced moves)
-
-* All the cash payment are merged into a single one statement line. This
-  feature is usefull if the user use OpenERP as a calculator, writing
-  for a payment:
-
-1. Payment 1/ Cash 50 €;
-2. Payment 2/ Cash -3,56 €;
-3. With this module, the final statement line is a single line Payment 1/ Cash 46,44 €
