How to stage ACH & CHK payment method EMP Exp Report data for PayCycle?

Hi,

We have 98% of employees Exp Reports payment method is ACH but 2% on CHK. So we are using Payment Method=ACH on EX BU setup. All ACH Exp Report data staged successfully for PayCycle but not staged for CHK employees data (getting Invalid Pymnt Method CHK for Empl 111111, Bank SetID XXXXX, Bank Cd XXXX and Acct XXXXX). Do we need to change the Payment method from ACH to CHK on BU setup then stage the CHK data? Don't we get any issue if any of the current CHK method employee had ACH previously?

Thanks,

L Mamidi.
