Summary :
Due to programming issues in the instantiation method, the ME_PROCESS_OUT_CUST Business Add-In (BAdI) does not execute the PROCESS_HEADER method as expected. This BAdI, intended for single active implementations, can cause an endless loop if incorrectly invoked. Users experience loss of instance attributes upon each call due to repeated new instance creations. The overall complication stems from the method's faulty instantiation process. The solution advised in the SAP note includes necessary corrections to the class and interface configurations to prevent recursion and ensure proper BAdI execution.
