I have some transformations included in the NCA.along with some Tables: when I run the program now I get the following message: “Object reference not set to an incidence of an object”. Now how would I know which object reference to focus on as the source of the problem. I ran into problems after I tried to correct some doses from the doses I was given originally. I reran the porgram and it worked then I eliminated some objects that were redundant. {The transformation routine has been working well for me}. Angus
Hi Angus, I am not sure if i follow your question correctly. a) if you are asking how to work out which object in your workflow is giving this error message then if you didn’t notice when executing them individually then when you execute a workflow you can see in the verification tab which object had a problem. (in the shot below I I have ‘forgotten’ to add statisitcs to a table template that requires them. 
b) IF you’re asking what “Object reference not set to an incidence of an object” means within a specific workflow object e.g. table then unfortunately it’s not always obvious. It may be that the e.g. table object in the workflow is corrupt in some way and it may take some steps to ‘reset’ it - it may be qucker to create that object in your workflow anew. In short the message “Object reference not set to an incidence of an object”, is not very explicit in itself I would carefully check the settings i have in that workflow object (apologies for the potential confusion in using the term “workflow object” with your problem.) If you can’t resolve please either post your project here or if confidentiality is an issue to support@pharsight.com. Simon
