| For several functions, GuiXT uses an RFC connection to the SAP System (Remote Function Call). In order to logon to the system, the RFC needs a user name and password. GuiXT uses the logon values stored in GuiXT profile. As a default, the GuiXT profile contains the user “SAPCPIC”. Since this user is often locked in productive systems, we suggest you create a special GuiXT RFC user with appropriate rights. For testing purposes, you can also fill in your own user name and password in GuiXT profile.
The following table contains the GuiXT actions that use an RFC connection, the name of the called function, the client in which the logon takes place, and the necessary user rights. Instead of logging on to client 000, you can ensure via a profile option that GuiXT always uses the current client. This has the advantage that no RFC user has to be created in client 000. On the other hand, if you have numerous clients, you then have to create the RFC user in each client. Creating an RFC user can be done in the SAP system with transactions SU01, SU02, SU03. As an example below, we show how to create the necessary user rights for web repository access. | ||
| Action | Client Function |
Required RFC user rights |
| Read scripts for transaction variants | 000 RS_HDSYS_GET_GUIXT_SCRIPT | S_RFC: RFC_TYPE=FUGR, RFC_NAME=SHD0, ACTVT=16 |
| Read web repository objects Objects “SAPWR:…” | 000 WWW_DISPATCH_REQUEST | S_RFC: RFC_TYPE=FUGR, RFC_NAME=SURL, ACTVT=16 |
| Read data dictionary (symbolic offsets in variables) | 000 RPY_TABLE_READ | S_RFC: RFC_TYPE=FUGR, RFC_NAME=SIFD, ACTVT=16 S_DEVELOP: DEVCLASS=*,OBJTYPE=TABL,OBJNAME=*,ACTVT=03 |
| “Call” statement in GuiXT Script | current client (function is specified in script) | S_RFC: RFC_TYPE=FUGR, RFC_NAME=xxxx, ACTVT=16
here xxxx is the function group of the called function |
| if Q[Role=...] and if Q[Profile=...] | current client BAPI_USER_GET_DETAIL | S_RFC: RFC_TYPE=FUGR, RFC_NAME=SU_USER, ACTVT=16
S_USER_GRP: CLASS=*,ACTVT=03 |
| Read images from “SAPDB:…” | 000 RS_HDSYS_GET_GUIXT_IMAGE | S_RFC: RFC_TYPE=FUGR, RFC_NAME=RSIMG, ACTVT=16 |
| Read images from “SAPIM:…” (Business Document Server) | 000 RS_HDSYS_GET_BDS_IMAGE | S_RFC: RFC_TYPE=FUGR, RFC_NAME=RSIMG, ACTVT=16 S_BDS_DS: CLASSNAME=cccc, CLASSTYP=OT, ACTVT=30 here cccc is the class name of the BDS image file |
