best practice for multiple tasks

[Hafila Hatta]

whats the best practice for achieving below use case?

1. multiple tasks will be created upon catalog submission 

2. tasks are created based on certain selection from user (must be simultaneously) 

3. req & ritm auto closed once all tasks are closed

I think your question is about standard service catalog.

- Generate multiple catalog tasks depending on the request item input in the request item flow. (Workflow change)

- When all catalog tasks are closed, the request item and the request are closed (OOTB)

[Hafila Hatta]

now i am stuck where the request item and request are not closed automatically based on OOTB 

[HIROSHI SATOH]

Are the request, request item, and catalog task records properly linked?
Can you see the catalog task from the related list of the request item?

[Hafila Hatta]

yes they're linked.
