Regarding Issues pertaining to buffer

Question

When ever we create a new BP we need to set error message based on partner type and country entered by the user on the WEB UI screen. To implement the same we have implemented the BADI   u2019BUPA_FURTHER_CHECKSu2019 based on user input and throw error message. To retrieve the data entered by the user on the WEB UI we are using the function modules 'BUPA_GENERAL_CALLBACK', 'BUPA_ADDR_CALLBACK',  'ADDR_GET_COMPLETE'. When the user enters the data and press enter the BADI is triggered as expected but the above mentioned function modules are not returning the data from buffer. Also when user changes the entered value and press enter again the BADI is triggered again but this time around again these function modules again are not returning the updated data. This implies that the latest values arenu2019t updated in the buffer. However the importing field IS_BUT000 of the BADI carries the updated value.
Please put some light and suggestions as to why the buffer is not picking up the current data.

Hi,
Yes the validation could be done but this would not stop the user from saving the BP details hence bypassing the validation.
We need to validate it and then save it in case everything is fine.
This could be achieved by rasing the exception in the BADI implementation class but this could be done only if we have the exception class defined in the exception tab of the BADI method which is not possible as the current BADI doesn't support this.
