Segment wise vendor Report FBL1n

Hi All

Requirement is for Segment wise reporting of Vendor Line Items in FBL1N. The problem is that the segment gets updated at the GL level i.e. when I see the vendor Invoice in "General ledger view" The segment gets populated.

We have done the following activities

1. Brought the option of Segment in Dynamic Selections in FBL1N through Se36

2. Changed the line item display in SPRO and brought BSEG-Segment in the Line item display.

Still not able to populate the Segment, which is present in Recon a/c but is not appearing in FBl1N or any other line item t-code.

Has anybody come across such scenario? Kindly revert.
