If you pay trip costs via person-specific vendors, you created an index on the personnel number in the vendor master record in customizing of the Travel Management System in the past releases 3.0D to 3.1x. At the same time, you created a matchcode ID P , in order to search for vendor master records via entry of a personnel number.
The matchcode definition has been changed as of release 4.0A. SAP now refers to elementary and global search help. As a replacement of matchcode ID P SAP has provided the elementary search help KREDP (with the short cut P) in general search help KRED.
