CCLM offers you the capabilitry for mass maintenance and an integrated view on all obejcts. But there is also the need to access directly an custom code object in CCLM without using the full CCLM application.
For this purpose a weblink feature is available.
Just put this link in your browser
https://<server>:<port>/sap/bc/webdynpro/sap/ags_ccl_objects?sap-client=001&sap-language=DE
and add the following addition parameters to th eURL
&WP_OBJECT_NAME=ZZTEST&WP_PGMID=R3TR&WP_TYPE=PROG
This will open the CCLM objects view for this single object. In this example the Program with name ZZTEST.
Now it is much easier to maintain attribute values for a single object and with a better performance.
To find out the server and port just open SE80: in Package AGS_CUSTOM_CODE do a single test in webdynpro application AGS_CCL_OBJECTS.
