Restricting account number and sub-ledger in PO Entry

Hello,

We have a requirement to control data entry in Purchase Order Entry (P4310). We want users to be able to enter only a specific range of account numbers and sub-ledger types in the grid.

This is to avoid incorrect entries and ensure better data accuracy.

Is there any standard way in JD Edwards to apply this kind of restriction? Any suggestions or best practices would be helpful.

Thanks in advance.
