Prerequisites
The DTColDwgDimTab record exists.
Pitfall: It is possible to create duty tables without a defined machine room, but doing so can produce a system error message after creating a new project in DigiPara Liftdesigner. Define a machine room unless you specifically intend a machine-room-less configuration.
Steps
1.) Add records for the new machine room(s). In the Machine Room Settings table (L_DTColDwgMRTab), add a record for each machine room configuration you need — for example a "No machine room" record and a "Machine room top" record — filling in width, depth, and offset fields (DTMR_MR_WIDTH, DTMR_MR_DEPTH, DTMR_MR_DX_KD, DTMR_MR_DX_F0, etc.).
2.) Fill in the machine room door and panel settings. Complete the remaining machine room fields, such as door position and wall/panel settings (DTMR_DOOR_RID, DTMR_DOOR_WALL, DTMR_PANEL_1_WALL, etc.).
Result
At least one machine room configuration exists for the duty table, avoiding the system error that can occur without one.
