Thanks for reply, Rinkubhai.
I understand what you mentioned, but in my case the To be Collected amount is absolutely incorrect, it shows the open items which were already paid last week. And, if we go to the next screen i.e. Process receivables, it shows the correct open items and shows the correct last payment under payments tab, but somehow in first screen of work list, it shows incorrect values.Not sure why this bug, and that too just for one singular customer!
Thanks
