Specifying Tolerance Limits 

Use

When certain business transactions are entered that create costs on the corresponding Controlling-Element, the system checks whether the available budget or available released budget is sufficient. It uses the tolerance limits specified in Customizing for this check.

For more information on specifying tolerance limits, see the implementation guide (IMG).

Features

You can specify tolerance limits for each controlling area, budget profile, and different Business Transaction Group.

You can specify different tolerance levels with three possible options (issue with a warning [1], a warning and a mail to the project manager [2], or an error message [3]).

You can define the tolerance limits as the usage level, and / or as an absolute variance from the current budget or the release.

Usage Level
 This is the relationship between assigned funds and the budget, displayed as a percentage.

Absolute Variance
 This is the difference between assigned funds and budget, displayed in an absolute amount.

SAP recommends that you either specify a percentage usage rate, or an absolute variance for tolerance limits in availability control.

If you defined a percentage usage rate and an absolute variance as a tolerance limit for a budget profile and a transaction group, the action you specified is triggered if the assignments exceed one of the two tolerance limits.
