Field help (PYHCNALIN)

Specify the analytical nature to post the payment line to.
This field is entered if:

• for Bank<=>BP payment attributes, the pre-payment account or the payment header account is defined with analytical management.
• for the other payment attributes (Account<=>BP and Bank<=>Account), the payment line account, either coming from the accounting code of the payment attribute, or previously entered, is defined with analytical management.
  The natured entered must be compatible with the site of the payment line, the payment date and the account that has been defined as stated previously.
  By default, the suggested nature is the default nature of the account that has been specified previously.
