Detection Method: Suspicious Terms Screening for Customer Invoice Items

You can use this method to screen the text of customer invoice items for specific terms. Terms that are thought to be suspicious can be specified and grouped to lists using the Suspicious Terms tile in SAP Fraud Management.

Logic

The execution procedure checks if the field SGTXT in table BSEG contains a term specified in a list. The screening logic, which uses fuzzy logic, is encapsulated in the generic procedure PR_SCREEN_TERMS. To improve performance, the selection procedure’s input is split into 20 packages. The generic procedure is called for each package, which leads to parallel processing and therefore faster screening.
