Header price into revenue account posting

Hello,

We have a condition type with calculation type is set as FIXED VALUE and relevant for header condition. When we insert the price in document header for header condition type, system automatically replicates/split the price into line item wise and during revenue account postings, system post the value for each line item instead the header price, example - PRICE IN BILLING DOCUMENT

Header Price: Stamp Value: 100 USD

Line Itme 1:

Quantity: 1

Basic Price : 200

Stamp Value : 50

Line Item 2:

Quantity: 1

Basic Price : 200

Stamp Value : 50

Revenue Account Posting -

Customer 500 Dr

Revenue Line 1: 200 Cr

Stamp value: 50 Cr

Revenue Line 2: 200 Cr

Stamp Value: 50 Cr

However we need the value in revenue account posting as below -

Customer 500 Dr

Stamp value: 100 Cr

Revenue Line 1: 200 Cr

Revenue Line 2: 200 Cr

Please suggest

Best Regards,
