SAP Error Message - Details

• Message type: E = Error

• Message number: 301

• Message text: Number range for info structure libraries is exceeded

What causes this issue?

Libraries are used for storing planning layout data internally. The
library name is automatically assigned in the background to each info
structure when a planning layout is created for the first time for a
new info structure.
Only a limited number area is available for assigning a library to the
application. The available number area has already been exhausted.
It is no longer possible to assign new library name for more info
structures. Furthermore, it is no longer possible to enter new planning
layouts for a planning step that links to the relevant info strucute
(database table).
