Additiona amount instead of actual amount in IT Declaration 80 & 80C

Hi all,

I am new to configuring IT Declarations in ESS/MSS. In SAP Standard application for IT Declaration for 80 & 80c, there is an column called Additional Amount. But in IT 585 & 586 , I cannot find any Additional Amount, instead Actual & Proposed is there.

Then what is the need of this Additional amount in ESS Create IT Declaration, if we fill additional amount & send it & get it approved, which infotype will it get updated in 585 & 586.

Please advice.

Thanks,

Namsheed
