ABAP ZXLWB_CALLFORM - Export Two Separate Data Sections in One Excel

[munzinh1]

##I have an ABAP report (ZMMHR003) that needs to export data to Excel using ZXLWB_CALLFORM. 
The data contains two vendors:1. Fixed vendor 104959 (always included)
2. Input vendor from selection screen (optional)

Current Structure:
- ZST_ZMMHR003_ITEM with all fields for both vendors
- Single table GT_OUTPUT contains mixed data

Requirement:
In Excel output, I need to show TWO SEPARATE SECTIONS:
- Section 1: Vendor 104959 data with header "I."
- Section 2: Vendor Input data with header "II."

Current Code Issue:
All data is mixed in one table, and ZXLWB template shows everything together.
