Hi @Shou 

You are currently using a Update projection action, you’d need to use a call projection action to use a call method. IFS Cloud uses Read, Update, Delete, and Call actions for projections.

Here is an example where I used a call projection action in my workflow

For your example though, I’m assuming the ConfigID parameter is either not called “ConfigID” but ConfigId or the projection doesn’t have access to that field, so you’d need to update a different projection. I can’t say for certain without seeing the error.

Thanks,
Bryan

Thanks for you answer.

my understand is 

Call   -  for projection’s Action and Function

Read, Update - for projection’s Entity

Currently, I just want to “PATCH” one Entity(not call an Action) , so “Update” is the correct selection.

meanwhile, you are right, ConfigID should be ConfigurationId.

But still , I get the ETag Error

I found the answer for it.

※tried with 23R1.

before you “Update” an Entity,

1) you have to “Read” it to get the Etag , 

2) then in the “Update” part

    just simply pass all Path Parameter and Update Parameter together 

after that , all works fine.

Hi @bdoucette 

I have some doubt about parameters in Call Projection task in workflow.

Can you please clarify some issues for me about passing parameters in Call Projection?

Thanks
