Avoid document changes when status is I1005 (completed)

Hello *,

I want to lock a business transaction (one-order "activity") for further maintenance in case the status is set to "completed". I have to ensure that no further changes are possible when the status is completed.

CUSTOMIZING-SETTINGS

status profile:                     CRMACTIV

status:                                    ERLD

system status:                         I1005

triggered business tx:          FINI

--> standard business tx:     "complete" with value "set"

--> addinitional tested business tx: "lock document" with value "set"

I have checked the following threads but they did not fit/solve my situation:

In general we do not want to hide the "change" button in the WebUI.

Any suggestions?

Kind Regards

Thomas
