It is possible for link nodes in SAS^® Marketing Automation 4.4 or SAS^®Customer Intelligence 5.1 Campaigns to become locked if the diagram is dynamic and they share a common ancestor diagram.

Expect to see an error similar to this in the macore logs.

This will occur only if the upstream diagrams are linked and have had their counts cleared or if one of the cells(4.4) or diagrams(5.1) in the Communication is Dymanic. The solution is to ensure that the upstream link nodes do not reference a common ancestor diagram.

In SAS^® Marketing Automation 4.4 for example:

If you have two diagrams, Diagram1 with a single select node (Gender = 'F' and Gender = 'M'), feeding a cell 'Cell1' OnChange. Update the counts on the cell and save.

Daigram2 with a link node from 'Cell1' and a select node (0 =< Age =< 20)—feed these into an AND node, then a cell 'Cell2' OnChange. Update the counts and save.

A communication with two link nodes, Link1 fed by Cell1 Link2 fed by Cell2. Mark the Exclude check box AND these together and feed the results through an OnChange Cell (Cell3) into the communication.

If you schedule and execute this campaign then everything works OK.

If you clear the node counts on all diagrams and schedule the campaign or make Cell3 Dynamic, you will see the error.

To work around this, simply save a copy of the first diagram under a different name (Dagram3 with link cell Cell4) and replace the Cell1 link in the Campaign diagram with a link to Cell4.
