Passing sys_id between screens in Mobile App Builder (Need Spare Part → Spare Parts List)

[RaoFahadA]

Hi everyone 👋,

I’m working on a Mobile App Builder use case where a technician opens a record (ticket) and clicks a Need Spare Part button. This button redirects to the SAHL Spare Parts list screen, and I want to pass the current ticket’s sys_id to that screen so I can attach the selected spare parts to the correct parent record later.

Here’s what I’ve done so far:

• Added a UI parameter named parent_sys_id (carried ✅).

• Set the Function table to x_nah_nhc_cfm_nhc_community_facility_management (ticket table).

• In Redirection destination fields, mapped:

  • Source field → sys_id

  • Destination UI parameter → parent_sys_id

  • Type → Field

• On the Spare Parts list screen, added a UI parameter also named parent_sys_id with input type = Source field, input source = Auto fill, and carried = ✅.

However, when I open the Need Spare Part function, it redirects correctly, but the parent_sys_id value is not appearing on the next screen (it seems undefined).

Can anyone guide me on:

1. The correct configuration for passing a sys_id between screens in Mobile App Builder?

2. Whether the List Screen should use a “Screen Parameter” or “UI Parameter”?

3. How I can verify or debug that the parameter is being passed properly?

Thanks a lot in advance! 🙏
