Line item is not visible after a PO is created using PR

Hi All,

We have created a PR using two material number 100-100 and 100-250. Using this PR we created a PO using ME59N transaction. The problem here is after the PO is created when viewed the PO using ME22N only one line item for material 100-100 is showed up. Are there any configuration steps to be done to create PO on both the line items. Could help in solving the problem.

Thanking You in advance,

Regards

Ram
