Hi Arnav,
There are some pre-requisite configuration:
1. Change field status of Customer Account group:
Path: IMG > Financial Accounting (New) > Accounts Receivable and Accounts Payable > Customer Accounts > Master Data > Preparations for Creating Customer Master Data > Define Account Groups with Screen Layout (Customers)
a. Choose your customer group, choose General data tab, choose Control tab, change status of "Vendor" field to Optional.
b. Choose your customer group, choose Company code data tab, choose Payment Transactions, change status of "Clearing with vendor" to Optional.
2. Change field status per Activities:
Path: IMG > Financial Accounting (New) > Accounts Receivable and Accounts Payable > Customer Accounts > Master Data > Preparations for Creating Customer Master Data > Define Screen Layout per Activity (Customers)
NOTE: you have to change the status of necessary fields in all activities (Create, Change, Display) in all level (Accounting, Centrally)
a. Choose General data tab, choose Control tab, change status of "Vendor" field to Optional.
b. Choose Company code data tab, choose Payment Transactions, change status of "Clearing with vendor" to Optional.
3. Change field status of Vendor Account group:
Path: IMG > Financial Accounting (New) > Accounts Receivable and Accounts Payable > Vendor Accounts > Master Data > Preparations for Creating Vendor Master Data > Define Account Groups with Screen Layout (Vendors)
a. Choose your vendor group, choose General data tab, choose Control tab, change status of "Customer" field to Optional.
b. Choose your customer group, choose Company code data tab, choose Payment Transactions, change status of "Clearing with customer" to Optional.
4. Change field status per Activities:
Path: IMG > Financial Accounting (New) > Accounts Receivable and Accounts Payable > Vendor Accounts > Master Data > Preparations for Creating Vendor Master Data > Define Screen Layout per Activity (Vendors)
NOTE: you have to change the status of necessary fields in all activities (Create, Change, Display) in all level (Accounting, Centrally)
a. Choose General data tab, choose Control tab, change status of "Customer" field to Optional.
b. Choose Company code data tab, choose Payment Transactions, change status of "Clearing with customer" to Optional.
Business process:
- In vendor master data, you have to fill the customer code in "Customer" field  and tick on "Clearing with cus" checkbox
- In customer master data, you have to fill the vendor code in "Vendor" field and tick on "Clearing with vendor" checkbox.
Then, post transaction as normal.
Check report:
You can check all items in report FBL1N or FBL5N.
Example: inFBL1N - Vendor Line Item Display, in the selection screen, you tick on "Customer items" checkbox, the report will show all items, even though you post in Vendor or Customer size.
Do the same with FBL5N.
