Why in transaction FBL3N the layout customer is not exist?
FBL3N layout is only to view General ledger transactions. For viewing customer/vendor related transactions use FBL5N and FBL1N respectively. These tcodes will give you option to select customer and vendor.
If you require Cust/Vendor A\c in FBL3N, you need to do this:
IMG > Financial Accounting > General Ledger Accounting
> G/L Accounts > Line Item Display > Define Special Fields for Finding
and Sorting Data > Define BSEG & KUNNR table and field name respectively.
Tables used by FBL3N and FBL5N
The tables used by T code FBL3N and FBL5N are:
FBL5N for customer line items will use BSID and BSAD (for open items and cleared items respectively).
FBL3N for G/L line items will use BSIS and BSAS (for open items and cleared items respectively).
When you post a document on a customer, the amount you post on this customer is reflected in the reconciliation account as well, but you may or may not see this in FBL3N. Please check the "Line item display" indicator under control data in FS03 for your recon account. If this field is checked, only then you will be able to see the line items in FBL3N.
Usually for recon accounts, this field is not checked.
