Sadly that is not possible in that comprehensive manner as you describe it. We have had this as a feature request w/ SAP development for years.
There are at least 2 restrictions here:
- The Change Request UI is a BOL object, and the current WebClient UI Framework does not seem to support the linkage as a whole (despite that FPM does)
- Navigation to a Sub Page from the error message is not supported by FPM. This would also have to update the lead selection on the main page, so that the Sub Page shows the correct data
You normally get the linkage only:
- For WDA errors (e.g. entering a string into a number field, entering an invalid date, ...)
- In MDG-M, for some messages from ERP backend. This is accomplished by writing the error log directly from the application. Linkage also only works if error field is visible on current screen.
