Control on production order consumption agianst BOM

Question

HI Experts,
Post Implementations i have two issues related to production order.
1.Can we stop production order from confirmation if consumption of material are excess than what is defined in BOM ?
If yes, what setting i have to do in system.
2.Our users are replacing the material in production order against what has defined in BOM, if this replacement of material has maid then system should not allow user to confirm the order. i this is possible ?
If yes  please let me know what changes i have to do in system
Thanks in advance

Dear Parag,
Check with these user exits in T Code SMOD,
PPCO0007  Exit when saving production order
PPCO0008  Enhancement in the adding and changing of components.
Documentation for PPCO0008,
The enhancement serves to check components that have been added to an order or changed
for example, against a standard material database).This check can reject the transfer of components to
the order in some circumstances or replace the material number with another.
The enhancement is given the material number, the plant and the storage location of the component
entered by the user (or of the components the user has changed). Also, the order header data is
copied to the structure I_ORDER so that the check can also include order-related values. However,
changes to values in this structure are not copied!
The check should copy back the material numbers to be processed (as well as the corresponding plant
and storage location) in the structure E_MATERIAL. If the data was changed then the structure
E_MATERIAL is always filled completely!
For the material returned (if E_MATERIAL is filled) the checks specified
in the program standard are run. It can happen that the enhancement is
called up for the replaced material number!
If the component is not to be copied at all then the check must trigger
the exception MATERIAL_REJECTED which then leads to the adding or
changing being cancelled.
Partly for this reason but also for example for the case of one materia
number being exchanged with another there is the structure E_MESSAGE in
which a message can be copied back to the calling program. The followin
belong to the message: the application, the message number, the level o
gravity (information, error, warning,...) as wellas four variable texts
that replace the corresponding place holders in the message. If this
structure is filled then the calling program makes sure that this
message is displayed. In the application CO the message 877 was already
created - it can be used to tell the user that a material number has
been exchanged.
If the exception MATERIAL_REJECTED was set and the structure E_MESSAGE
was filled then the calling program displays the message. However, if
the message is not an error or a termination then this message is
displayed as an error.
