Authorized severs and folders that are needed for HTTP-based communication of Web Dynpro UI elements are listed in a white list. A certificate is stored by the administrator on every application server to validate white lists.

File upload, file download, and the execution of programs will not work correctly without a white list.

Prerequisites

To be able to work with a white list, you first need a certificate for the affected SAP system. This certificate is stored in table WDR_ACF_WL_CERT.

  • You therefore must have created a certificate using transaction WDR_ACF_GEN_CERT (see Creating Certificates).

  • Library SAPCRYPTOLIB must also be installed. For more information, see SAP Note 455033—SAPCRYPTOLIB. Use transaction STRUST to check the installation of SAPCRYPTOLIB and to determine if entry SAPCRYPTOLIB exists.
