Hi Sharon, if you don't have different ER contributions amounts per coverage tier, I think you can just create one plan and rely on the limits in T511P. With this approach you can configure one EE contribution variant leaving the maximum blank in the contribution rule. Then use KONST HSASL (HSA limit Self Only Coverage) and HSAFL (HSA Limit Family Coverage) in table T511P to prevent the employee from contributing more than the limit based on their medical plan coverage tier. We switched our method a few years ago but I seem to recall that HRBEN0001 would not allow a contribution amount over the T511P limit to be selected but definitely test that because my memory can be a little unreliable 
. Hope this is what you're looking for.
Take care!
