Avoid processing of WPUBON in certain case

Hello Experts,

We have a requirement for an Invoicing Scenario for a SAP IS R System. In this scenario, in case of a Particular Condition Type (ZXXX) in WPUBON IDOC (Segment E1WPB03), the further processing of Goods Movement (Article Document) and Billing Invoice (Billing Document) is avoided.

I know there are following user exits which may be used, however I am not sure if this is possible and if yes how -

EXIT_SAPLWPUE_050              POS Inbound Processing Messages

EXIT_SAPLWPUE_102              IDoc WPUBON01 Before Document is Posted

EXIT_SAPLWPUE_104              IDoc WPUBON01 Before Inbound Processing

EXIT_SAPLWPUE_105              Check Whether IDoc Transaction WPUBON01 Is Compressable

EXIT_SAPLWPUE_106              IDoc WPUBON01 Process User Segment

EXIT_SAPLWPUE_109              IDoc WPUBON01 After Inbound Processing

Any pointers are appreciated.

With Regards,

Vikrant
