How To Fix TR291 - Choose another package for reservation &1 &2 &3

SAP Error Message - Details

• Message type: E = Error

• Message class: TR - Change and Transport System

• Message number: 291

• Message text: Choose another package for reservation &1 &2 &3

What causes this issue?

You cannot choose package &V4&.
The package must belong to the same namespace as the reserved name
range &V3& for object type &V1& &V2&, and a generally used, local
package may not be entered.
For name ranges with <DS:DE.NAMESPACE>namespace</> prefixes, you can
only choose a prefix package.
For partner name ranges, you can only choose a package that contains
the <DS:DE.NR_PROJECT>partner project number</>.
The package should give reservations a unique project assignment. It is
only by the assignment to a regular project package that you can
document that you would like to use a name range exclusively. For this
reason, you are not allowed to enter the package $TMP used in all
projects. (To allow you to create local objects within your project
(package $TMP), which can later be reassigned to your project package,
objects can also be created in package $TMP, differing from but with
reference to the reservation entered.)
