| # Package VRCs (ttadv1511m000) This session lists the package VRCs, which you can define and modify in the Package VRCs (ttadv1111s000) details session. This session also shows the derivation structure. To print a complete overview of the derivation structure, click Print, and click Print Package VRC Derivation Structure. If LN stops responding while you use this session, the VRC derivation structure can be damaged. To repair the package VRC structure, you must run the Repair Package VRC Derivation Structure (ttadv1211m000) session when you restart LN. Note You cannot start the Package VRCs (ttadv1111s000) details session if the Purge Entire Package VRC (ttadv6255m000) session or the Purge Specific Software Components of Package VRC (ttadv6256m000) session is in use. VRC An upgrade of a package, for example, B61. Each change in the functionality of a package results in a new version. A version can contain several releases. Release An update in a version. For example, 'B61 a', where 'B61' represents the version code, and the 'a' represents the release code. Each update results in a new release with a new release code. Customer A code that identifies a customized software package. For example, B61O_a_cus1, where 'B61O' represents the version, 'a' represents the release, and 'cus1' represents the customer extension of the customized software. Derived from The version of the preceding VRC from which the package VRC is derived. Release The release of the preceding VRC from which the package VRC is derived. Customer The customer of the preceding VRC from which the package VRC is derived. TIV The TIV number of the package VRC. During the dump or compilation of a session or form, the TIV number determines the actual functionality in the session/form dump. If the TIV number is not set, or is equal to zero, sessions and forms are dumped in the highest available version. The TIV number on VRC level is important on maintenance systems where different versions, or feature packs, are customized and/or maintained. The TIV number ensures the sessions/forms are dumped in the correct version. This table shows the available TIV numbers:
