SEM CPM BSC - Assessment entry through UMB_LAUNCHPAD_WEB

Hello

I have a Balanced Scorecard defined in SEM.

The users can entry "assessments" each month for each measure.

Something happened, and right now it is not possible to enter "assessments" through the web interface (transaction UMB_LAUNCHPAD_WEB) of the balanced scorecard.

The assessments can only be entered through the GUI SAP using transaction UMB_PRES1.

The users used to enter the assessments through the web interfase, but now this feature is disabled (The button "assessment" dissappear), maybe someone change something that i don't know.

Please help me in order to enable the entering of "assessments" through the web as it is possible now through the SAP GUI way.

Thanks in advance for your valuable help.
