LT12 TO confirmation error for multiple line items

Hi Experts,

We recently upgraded to ECC 6 DIMP EP6. We are not able to confirm TO with multiple line items. It is failing with an error message VL 198 that 0 quantity of material is available. We are able to confirm TO line items one by one. This TO is created for a delivery picking request. We tried with a configuration change for the delivery line item category availability check as Y as mentioned in this note 1653018. But still not working fine. Please let me know any relevant SAP note for this issue.

Thanks
