Notes for Problems with Availability Control

Problem	Symptom	Cause	Solution
Availability control is not reacting, despite correct settings and activation.			Check to see if the corresponding entries are in the control tables TRWCI and TRWCA (see below: Entries in TRWCI and TRWCA).
Activation type 1 (activation with budget allocation) was selected for activation of availability control. Availability control is to be executed on a project, although the project has not yet been budgeted.			Post an original budget to the top WBS element. Then execute a return for the same amount. The current budget is zero. ( ) Availability control is now active.
Availability control with action two (mail to project manager) does not send a mail when the assigned values are exceeded.	An error message appears.	No manager name has been entered in the WBS element, or in the project definition.	Enter the project manager name in Customizing, under Project System → Structures → Operative Structures → Work Breakdown Structure → Create Person Responsible for WBS Element.
	A warning appears.	In Customizing for the project manager, the user has not been entered correctly.	Enter the user name of the project manager in Customizing, under Project System → Structures → Operative Structures → Work Breakdown Structure → Create Person Responsible for WBS Element. ( ) Note that you need to enter the name in upper case letters.
	Neither a warning nor an error message appears.	Availability control is not active, or the tolerance limits have not yet been exceeded.	Activate availability control or maintain the tolerance limit accordingly.For more information, see: Activating Availability Control Specifying Tolerance Limits
When you post a goods receipt or enter an activity, this does not trigger an availability control action, although the tolerance limit was exceeded.	The system does not check the assigned values during goods receipt.	For technical program reasons, only the assigned value is updated when you post a goods receipt, or enter an activity.	Check whether you can solve the problem by using one of the solutions suggested below (see below: Posting a goods receipt or entering an activity ).

Entries in TRWCI and TRWCA

The program control table TRWCI (in which the installed components are stored) must contain the COFC entry (Controlling Funds Control).

The TRWCA table contains the same components (fiscal year-related) as the TRWCI table. You can use this table to deactivate specific components for certain fiscal years. In the TRWCA table, the COFC component should be active until the year 2050.

Posting a Goods Receipt or Entering an Activity

Use the commitment values from the purchase order for the budget check.

Check whether tolerance limits were maintained for the purchase order transaction group. Before the purchase order, activate availability control.

Check whether you can work with unevaluated goods receipts. In this case, the system updates the assigned values only once the goods receipt has taken place. When goods are received, the system checks the assigned values and if necessary, triggers the corresponding actions.
Do not allow any more account assignment changes for the goods receipt posting.
