Hi Shanthi,
hope, the user did not enter bank details during raising invoice. for one time accounts the bank details needs to be entered at the time of invoice creation.
One time customer and vendor master are common for so many vendor and customer. You should not keep address and bank details are input field. it should be suppresed.
For all customers / vendors with whom you rarely do business, a special customer/vendor master record should be created. that's why it is called as one time vendor / customers. then what is the purpse of creating separate account group for them ?
When you post to a one-time account, the system automatically goes to a master data screen. On this screen, you enter the specific master data for the customer, which is stored separately in the document. This includes name, address, and bank data
you need check the account group. whether one time vendor option has been ticked in the account group. so when you enter invoice it will ask bank details. If it take from master than will you change every time the bank details from master. how you will come to know when business person going to precess next invoice for other vendor but with same master ?. business people ( who run APP/F110 will not aware about the payment details). it may go to wrong vendor than you need to answer them
