Logon to system DEV failed (System DEV does not support Eclipse based ABAP Development Tools)

Question

I get that error:

Logon to system DEV failed (System DEV does not support Eclipse based ABAP Development Tools)

I have the credentials to the SAP system and I have already setup ABAP in Eclipse. But whenever I try to logon I get that error.

Answer 1

There are also a couple steps which need to be done in the backend system in order to allow connections from Eclipse. There is a guide Configuring the ABAP Back-end for ABAP Development Tools on help.sap.com which outlines all the steps.

But the tl;dr is:

• The SAP NetWeaver version must support ADT. The lowest version is 7.3 EHP 1, but some higher versions might also require a certain Service Pack. See the document linked above for the complete list.
• The developers using Eclipse need the roles SAP_BC_DWB_ABAPDEVELOPER and SAP_BC_DWB_WBDISPLAY (or roles with equivalent permissions). You can assign roles with transaction SU01.
• The following ICF services need to be enabled in transaction SICF:
  • default_host > sap > public > bc > abap > docu
  • default_host > sap > public > bc > abap > toolsdocu
  • default_host > sap > bc > abap > docu
  • default_host > sap > bc > abap > toolsdocu
  • default_host > sap > bc > adt
  • default_host > sap > bc > webdynpro > sap
• The following system profile parameters need to be set in transaction RZ11:
  • login/create_sso2_ticket = 3
  • login/accept_sso2_ticket = 1
