Validations on Purchase order creation.

Hi Oracle Friends,

Is there any setup/other check points to inform  buyers with appropriate message while creating Purchase order in following conditions.

 

1. Error message should be displayed if the purchase order lines have unit price less than or equal to 1
2. Warning message to be displayed if the purchase order lines do not have the contract purchase agreement/Blanket Purchase agreement while creating standard Purchase order for configured items.
3. Warning message to be displayed if the purchase order lines do not have the sub inventory referenced in the distribution tab when the destination type is INVENTORY.

Thanks

Laksh
