Create accounting in AR group multiple receipt

Hi

we just create new entity in our system for a new acquired company

i have an issue with the transfer between AR and GL module for AR receipt

we create multiple receipt in AR(same bank) and after create accounting receipts are gather in one amount in GL

i assume this may be a subledger setup but not able to find

looking for an idea or a way to investigate

Thanks for your help
