Sales Order Approval based on Line EFF from one of the lines

Summary:

We have a requirement to trigger approval for the sales order based on Line level EFF.

The requirement is, if the EFF is not blank on any one of the sales order lines then order should go for Approval.

However, the rule is checking not blank for all the lines, if all the sales order lines EFF is not blank then it is going for approval. if any one of the lines is Blank then order approval is not triggering.

Can we achieve to validate if any one of the lines EFF is not blank, the sales order should go for approval.
