E1 - Package Naming Convention

Hi, how can i re-use the update package name ?

You cannot build a new package using the same name as the currently deployed package. Due to the fact that a deployed package is considered active, you cannot reuse the package name in a new build. The deployed package is in use by services. The recommendation is to build a new full package with a different name. Once the new package is deployed, you can now reuse the old package name for a future build.

 For the package name, refer this :

Package Name Length Limitation

Starting with EnterpriseOne 8.12 application release level onwards, the length of a package in EnterpriseOne is limited to eight characters. The field is called Package Name, Data Dictionary alias PKGNAME, on the Package Assembly - Package Information form (P9601 / W9601F).

The Package Management guides (for Tools Releases 8.96, 8.97 and 8.98) correctly state in the "Assembling Packages" section:

"The name of the package cannot be longer than eight characters"

However, the System Administration guides (for TRs 8.96, 8.97, 8.98) incorrectly state in the "Understanding Naming Conventions" section:
The naming conventions for a package are as follows:
* Limited to 10 characters.

Answer:  The correct length limit is eight characters. Documentation ICE 1805247000 was entered to report the documentation error in the System Administration guides.

NOTE:
The Package Assembly application will generate a red error if you enter a package name over 8 characters, but in reality codewise it will accept it up to 10 characters. The reason it was changed to allow only eight characters only is because of the mobile packages.

When you build a mobile package, it appends the packagename with " _M ", e.g. if your package is named DVF092908 (9 characters), it would attempt to change it to DVF092908_M (11 characters). The PKGNAME DD item only has a length of 10 characters, so the 11 character name would be invalid. If you're not using mobile packages and aren't bothered by the red error that pops up, then it's probably OK to enter in 10 character package names.
