• What is the cause and solution for SAP error message LTBN007 - Entry-exit nodes do not exist for work centers ?

  The SAP error message LTBN007 indicates that there are no entry-exit nodes defined for the work centers in the context of a production or logistics process. This error typically arises when trying to execute a transaction that requires a valid routing or work center configuration, such as during the creation of a production order or during the execution of a logistics process.
  Cause:

  Incorrect Work Center Assignment: The work center assigned to a routing or production order may not be valid or may not exist in the system.
  Data Inconsistency: There may be inconsistencies in the master data related to the work center, such as missing or incorrect entries in the relevant tables.
