在Azure Data Factory V2上构建此管道

Question

I am currently trying to set up this pipeline on Azure Data Factory V2 (as you can see in the picture attached). In summary this ERP system will export in a monthly basis this report (CSV file with actual and forecast data) and this will be saved in a blob container. As soon as this file CSV is saved, an event trigger should activate this stored procedure that will - in turn - erase all actual data from my fact table in Azure SQL as this gets replaced every month.

Once actual data is deleted, the pipeline would have subsequently a copy activity that would - in turn - copy the CSV report (actuals + forecast) to same fact table in Azure SQL. Once the copy activity is finished, the HTTP logic APP would delete that new CSV file from the blob container. This workflow would be a recurrent event to be carried out very month.

So far I have been able to run these 3 x activities independently. However, when I join them in the same pipeline, I have had some parameters errors when trying to "publish all". Therefore I am not sure whether I need to have the same parameters for each activity in the pipeline?

The JSON code for my pipeline is the following:

请按照此文档配置您的Blob事件触发器，并将正确的值传递给您的参数。
