Cause

Within the routing path network, a topology function has been found that is not a main function and whose function definition does not match the associated multi-line main function in the schematic.

Solution

1. Locate the topology functions in your routing path network using the Go to (graphic) function from the popup menu in the Message management dialog.
2. In the popup menu, select the Go to 2nd coordinate menu item.
   
   A jump is made to the multi-line counterpiece – the main function.
3. Call up the Properties <...> dialog of the main function, and switch to the Symbol / function data tab.
4. Remember the entry in the Definition field under the Function data (logic) group box.
5. Close the Properties <...> dialog of the main function using [Cancel].
6. On the insertion point of the main function, open the popup menu, and select the Go to (counterpiece) menu item.
   
   A jump is made to the topology function.
7. Call up the Properties <...> dialog of the topology function, and, here too, switch to the Symbol / function data tab.
   
8. In the Function data (logic) group box in the Definition field, click [...], and set on the topology function the same function definition that is also set on the main function.
9. Click [OK] to close the Properties <...> dialog, then start a new project run.
