<RmtInf> - <Strd> shows only one invoice details instead of all invoices

Hello Experts,

I have a query regarding DMEE tree.

Currently the output of xml is as below :

<RmtInf>

<Ustrd> Inv 1 Inv2 Inv3 Inv4</Ustrd>

<Strd>

<RfrdDocInf>

Details of Inv 1 only

<RfrdDocInf>

<RfrdDocAmt>

Details of Inv 1 only

<RfrdDocAmt>

<Strd>

<RmtInf>

Only one invoice appears in RmtInf -> Strd

Can anybody please guide which attribute (Level, type, length) could be wrong for which node (<RmtInf>, <Ustrd>,<Strd>)..?

Regards

Nisit
