Whenever a financial transaction takes place in the system, the postings concerning it are created by the predefined posting types and rules defined in IFS/Accounting Rules. This means that you do not have to do anything manually as long as you have defined your rules correctly.
However, sometimes you want to decide a code part value, depending on specific information, i.e., you choose not to decide a rule for this code part for all posting types affected or it is not possible to decide a rule. In these cases, you can define a pre-posting which will not allow you to proceed with the inventory issue until a relationship is established between the code part and the inventory part line. The code part value that you enter as a pre-posting will then affect several postings created for this inventory part. An example of this is when you want to charge a specific Cost Center for the inventory parts issued. Note that this also includes issue handling unit and the content of a handling unit.
The postings that will be affected by the pre-posting are generally all postings concerning expenses, revenues, and WIP. This is determined in Business Event/Posting Info where you can see whether a posting for a specific system event is affected by the pre-posting on the inventory issue, or not. Note that pre-posting will generally not affect the inventory cost postings (M1 posting). Pre-posting will be used when posting transactions registered for non-inventory parts, no-number parts and eventually overheads. An exception to this are transactions related to material connected to a project.
Basic financial data and sets of rules for IFS Applications are managed in the IFS/Accounting Rules. Besides the regular rules you also have to define whether you want to use the pre-posting functionality in IFS/Accounting Rules. This is done by entering a specific posting type for each order type (see Prerequisites) and what code parts for which it should be possible to enter pre-posting.
