How to disable 'Book Order' BUTTON in OE - using Form Personalization

 Hi,

Verion is 11.5.10.CU2

User needs to DISABLE 'Order Book' button for these conditions.

1)Order Type is Cash -- (We know how to derive that)  + (AND)

2)Order Date is not EQUAL to current-system-date (That can be checked as well).

i)Now the question is which trigger event is to be used?

ii)How many 'Action lines' are needed.

iii)In which block to find / locate  'Book Button'  and what is its item-name in the said block.

On ePoint also be NOTED  that Order may be old-dated and the user finds the Order and directly presses 'Book Button' without any changes in Order Header or Order Lines.
