COMPOSE-E-STARTFLD, Failed to start task "mapping_1".

[sardarabdullahkhawar]

Hi all,

hope you guys are doing well. I have tried to create tables and then validated the mapping but when i try to run this. It gives me this error without executing "COMPOSE-E-STARTFLD, Failed to start task "mapping_1". View log file for more details". I cannot find logs as it is not in the logs tab. Only tables gets created in the data warehouse but data is not populated. I have tried multiple things by deleting the tabl

e & recreating it. Changed the schema as i couldn't go again to the run step again.

So far, i have been disappointed with Qlik Compose community and i have posted 2 questions earlier. One of them is permanently deleted.

Hello @sardarabdullahkhawar 

I am guessing something is corrupted and would suggest Dropping and recreate Datawarehouse Table, Generate Task Statements and Run the Task.

And also i would suggest opening a support ticket with us to analyze further.

HI @sureshkumar , I have tried this but it didn't work . As i have faced this problem for another project where i tried this solution "Solved: Data Warehouse already contains tables error while... - Qlik Community - 2004294" and it is giving me this error again    "Data Warehouse creation failed. Error: COMPOSE-E-DWHCONTAINTBLS, The data warehouse already contains some of the tables or views. Delete these tables and then retry the operation." . Tried every solution available, but it didn't work.

Hello @sardarabdullahkhawar 

Kindly try changing the Datawarehouse DB or change Schema name in Datawarehouse Connection Properties.
