Why did you post a batch COBOL question in the SMS & VSAM forum? I've moved it for you.
If the partial key is at the start of the key (which is something else you could have told us, rather than letting us guess), you can use a START to set your position. If the partial key is not at the start of the key, you can use an alternate index -- or what you want cannot be done.
