How to fix this error?

Missing authorizations:
Please check wether the RFC user has the necessary authorization to
create tables in the sender system (S_DEVELOP).
Conflicts with other Embedded Specifications:
If you are using multiple SAP LT systems with the same sender system
there could be a conflict situation where the current pre-selection
table has already been assigned to another SAP application table.
This situation can be resoveld by either deleting the mapping record on
the sender system (table CNVOM_PSTABMAP) or changing the pre-selection
table name on the LT system (tables CNVOM_PSTAB and CNVOM_PSTREG).
