Child Form not set on child creation

[wjjunyor]

Hey there, I don't know why, in a child form, the App isn't in any form filling the related origin ID code - 

Invoice Table: CdFatura (Index)
Relationship: Table Invoice: RLInvoiceItem

ORDERBY(
  FILTER(
    "FaturaItem", 
      AND(
        [IsDeleted] <> "Y", 
        [_THISROW] = [CdFatura]
      )
  ),
  [DtCadastro]
)

Guess it is related to this filter - But don't know why behaves this way!

InvoiceItens Table REF CdFatura - BUT when in InvoiceItens_Form it Does not show the column, does not receive it and do not record it
