I have a marketing rule in DTM (Rule A), that uses variables from a different rule (Rule B)
How can I adjust timings, so that Rule A fires after rule B.
Sorry for the delay here. I must have missed your question initially.
Based on the information given, you cloud change rule A to a direct call rule that is called by the custom code section of rule B. That way, rule A would only fire when rule B fires. There may be other ways of accomplishing this, but I would like to understand your use case better before suggesting anything further.
If I was you, I would implement rule A as a direct call rule, and then have Rule B to trigger rule A, then you are sure of the order...
