Dear Zia,
when v r making full pymnt then v will go with standard pymnt,
when v r making some pymnt then v will go with partial pymnt,
when v r making final pymnt excluding some pymnt then v will go with residual pymnt, (the part of amount which v r excluding it will comes under discount)
my query is as per your config, when am double clicking on amount line item in (residual pymnt), the amount is automatically posted.
as per my understanding standard and residual pymnt both are doing the same
if possible please assist me
