**Clarifying missing gross order**

I'm noticing that the order indicates there's a missing gross, but it seems like the user thinks I need to look that up. However, I should clarify that before I move forward with calculations. I need to return a clarification and cite references R1 and R7 in my explanation. It sounds like I should keep it short while addressing the blocker and asking for resolution, specifically regarding fields, decision, and reason_code clauses.

Reasoning
**Clarifying gross issues**

It looks like we have some missing gross information related to R7 and the month/reference. I need to clarify if there’s no need for a lookup since the user mentioned the reference is only available through lookup. However, since there's a blocker in the way, maybe a lookup isn’t necessary after all. I need to ensure we're using JSON with the exact fields for decision-making, including the reason code clauses and optional explanations. I'll also mention the unresolved blocker and ask for a resolution.

Reasoning
**Clarifying information needed**

I need to address a missing gross detail because the order specifies that I should clarify this immediately. However, the user mentions that there’s a reference available, and perhaps I don’t need to pursue it further. I need to pinpoint the exact fields to clarify, and I should cite the relevant clauses. An explanation is optional, but I should keep it short and specifically name the blocker when asking for a resolution. I’ll elaborate in JSON only.
