Checks and When They Are Performed
Note that package checks are always performed at the design time of the development object, not compile time or runtime. This means that dynamic uses of the object (such as calling function modules) are not checked.
The Extended Syntax Check (SLIN)
The extended syntax check also performs package checks and displays messages of the appropriate type (error, warning, information) where necessary. You can then navigate to the line in the source code where the problem occurred by double-clicking.
Prerequisites
You can perform the extended program check only on active sources.
Calling the Package Builder
Transaction SLIN or from SE38 through the menu path Programm ? Check ? Extended Program Check Then tick the Package Check checkbox.
Checking packages in the ABAP Dictionary (SE11)
You can perform a package check on either an active or inactive version of a Data Dictionary object, such as a table, view, data element, or domain. Type groups are an exception. However, you can check only the active version of a type group since it is a source.
Calling the Package Builder
Call the package check within the Dictionary tools by choosing Check ® Package Check.
When you activate a Dictionary object, the system performs the check automatically.
If an error occurs during a package check of one of SAP’s own Dictionary objects, this object is not activated. If the object has been created by a customer however, a dialog box containing a warning is displayed.
Object checks when releasing the transport
Checks are performed on some Dictionary object types when the relevant transport is released. The system administrator can specify whether or not the package check is activated.
