Different (Header) Condition Records for different Users??

Hi Gurus,

For some POs, we are seeing different header condition records for different POs. Can anybody help me out?

Here are the details.

For a PO, when one user is checking in ME22n, the following are displayed

Condition Type1 - PBXX (with gross price, Net Value with Tax and Net value with Discount)

Condition Type2 - ZX11 (With Amount and Actual price)

For the same PO, when another user is checking using ME22n, the following information is being displayed in addition to the above information

Same Condition Type 2 - ZX11 (But with zero amount) in one more line
