SAP Ariba integration conversion to Cloud Integration Gateway - Goods receipt extraction

Hello All,

Scenario- Goods receipt extraction from SAP ECC towards SAP Ariba using CIG.

We have implemented CIG recently for sending messages to SAP Ariba. When we post goods receipt for multiple PO in single material document we are getting below error.

How to make above scenario working for multiple PO GR in single material document.

In case of GR for single PO is successful.

Thank you,Sanjay
