• Implementation using custom logic (BAdI)

  This approach is recommended for advanced users with competency in ABAP coding. Here, the custom routine is implemented as custom logic through the filter-enabled Business Add-In (BAdI) Flexible Billing Document Numbering (SD_BIL_FLEX_NUMBERING). By creating a BAdI implementation with a filter value and mapping that filter value to a routine number, the BAdI implementation can be called every time a billing document of a given billing type is created.

  In addition to defining your own number range intervals (and, optionally, number range prefixes), setup involves writing the custom logic in the Custom Logic app to represent the required rules and subsequently performing two configuration activities in your configuration environment to map the BAdI implementation to a routine number. You then map the routine number to the relevant billing type.
