variant (obc4)
Field Status Variant is used to define the fields which are used for input like cost center, profit center,
plant, etc., which are entry fields, and hidden fields. Field status Variant is a tool which is provided by
SAP to assign the same set of properties to more than one object.
Example − We define fiscal year variant and it can be assigned to more than one company code. If a field
status variant is assigned to more than one company code, the same set of screen field will be displayed
while posting those company fields.

8.Posting key (OB41)
What is a Posting Key in SAP PF? Posting Key refers to a double-digit numeric key that is defined to
control the entry processes of document line items in an FI Transaction. These posting keys specify
whether the line item is a debit or credit entry account type. It also specifies the screen layout of the line
items.
9.Define document types (OBA7)
The document type is a key that is used to classify accounting documents and distinguish between
business transactions to be posted. The document type is entered in the document header and applies
to the whole document.
The document type has the following purposes:
       Differentiating between business transactions. Since the document type is shown for every line
        item, you can always tell what type of business transaction is involved. You can also use the
        document type for evaluation purposes.
       Controlling the posting to account types (vendor, customer, or G/L accounts). The document
        type determines which account types that particular document can be posted to.
       Assigning document numbers. A number range is assigned to every document type. The original
        documents from one number range should be stored together.
10.Define document number range (OBA7 FBN1)
Document Number range means
      a number interval from which document numbers are selected
      the type of number assignment (internal or external)
You assign one or more document types to each number range. The number range becomes effective via
the document type specified in document entry and posting. You can use one number range for several
document types. This means you can differentiate documents by document type but combine them
again for filing the original documents, provided you store your original documents under the EDP
document number.
11.Define Tolerance group (OBA4)
The tolerance group for Employees determines the maximum document amount the employees are
authorized to post. The maximum amount can enter as a line item in a vendor account or customer
account. A tolerance group is created and assigned to the employees.
