Trigger a workflow when we change an item attribute field in PPM

Hello experts,

We have the requeriment to trigger a workflow when we make a change in one item attribute. We know how to trigger it when we change the item status but we don't knw how to do when it is an attribute, does anyone know how to achieve this? It seems that it is possible because PPM has the workflow ID 00000000000002 for this,

Thanks for your hep,

Sara
