XREF3 in MIRO disappear when the user input po

[winnie_tian]

Dear experts,

I have added the XREF3 field to Details Tab according to XREF1, XREF2, XREF3 in MIRO – the ultimate solution | SAP Blogs.

When I manipulate MIRO just input posting date , XREF3 in Details Tab is visible . But when I input PO , XREF3 is invisible !

Is it my enhancement having some questions or lacking of IMG settings ?

Can anybody help me! Thanks very much !

Below is my code , there're a little different from the blog .

Check the field status variant customizing (Table T004F).   It is possible that the XREF-3 Field is suppressed eg. for reconciliation accounts.
