Incorrect Accounting after applying Receipt

[ERP-Implementor]

Hi All,

I am applying a receipt against imported invoice, When I view the accounting after creating draft accounting the system does following:

Debits Cash
Credits Receivable (but instead of crediting single receivable, it distributes the 20,000 amount of receipt across all 37 installments for this invoice based on percentages shown in distributions for that invoice)

I need to know why is this happening and how can I correct it

regards,
