Retro Payroll run after GL Accounts changes in new system

Hi Members,

We are upgrading our 47C HR-Payroll system to ECC 6.0. Due to requirements at Finance side, project team is proposing to change GL accounts codes and company code in the new system.

Need your expertise to check following:

1. How changes in company code and GL accounts affect Payroll Retro-calculation ability.

2. Can GL Posting program automatically determine the new GL Accounts based on new mapping of wage types and charge retro-adjustments to the new accounts.

3. If we enable retro for previous periods in the new system, will Posting program give error due to missing old GL accounts for retro-calculations.

Has anyone faced similar type of problem. Any help will be greatly appreciated.

Thanks

Amit
