Field help (BDFCY) 

This field uses the site code.
It can only be accessed if the budget is defined by site.
The code of the operation site is initialized by the site associated with the user code.
It can be modified provided it has been chosen from the list of authorized sites.
On entry of the second line, the system uses the value of the previous line.

If the budget is defined at site level, the site must necessarily be specified.
In that case, the Company field is automatically filled with the site company.
