Posting Key has control functions within the line items it controls
Defined at Client level and most imp con functions for a posting key are;
i. Determine which account type can be posted to
ii. Side of account (debit or credit posting)
iii. Field status of additional details or layout of entry screen
iv. Specifies whether the line item is connected to a payment transaction or not. (helps analyzing payment
history/notices)
v. Whether posting is sales relevant and sales figures need to be updated.
Std posting keys for customer/vendor invoices are
i. credit- 50 customer –31 Vendor
ii. debit- 01 customer – 40 Vendor
Standard posting keys for G/L account postings are;
i. 40 Debit posting key
ii. 50 Credit, posting Key
Field Status of document fields is influenced by Field status group and posting key and is determined by three factors:
i. Account type (S,K,D)
ii. Field status of posting key
iii. Field status of account.
As a general rule the account specific field status for G/L accounts
Field status with highest priority applies, Exceptions to this rule are:
o An activated biz area must be ready for input
o Entries in tax fields only possible if G/L account is tax relevant.
o Field Status group controls the field display during document entry.
o For each group of G/L accounts you have to define the status of every document entry
field.(required/optional/hidden)
o You assign field status groups to the respective G/L accounts in the G/L account master records. Each G/L
account has a field status group
If a doc is posted to a sub ledger account the field status group of the reconciliation account is used.
All the field status groups are summarized in one field status variant which is assigned to coy codes (mandatory)
Required, hidden, optional is priority. Hide + Required=Error
By changing the field status definitions of posting keys and field status group, the field status can be made
transaction dependant and account dependant.
Subledgers don’t have field status group and therefore a lot of posting keys are used.
In G/L postings differentiation is mainly made via different field status groups, therefore only two posting keys
40 & 50 are needed for G/L postings.
