• What is the cause and solution for SAP error message MQ155 - Package &1 is in phase &2; you cannot start conversion programs ?

  The SAP error message MQ155 indicates that a package is in a specific phase, and as a result, you cannot start conversion programs related to that package. This error typically occurs during the transport or upgrade process when a package is not in a state that allows for certain operations to be performed.
  Cause:
  The error message MQ155 is usually caused by one of the following reasons:

  Transport Issues: If the package is part of a transport request that has not been fully processed or is still being imported, it may lead to this error.
  Upgrade or Migration: During system upgrades or migrations, certain packages may be in a transitional state, preventing the execution of conversion programs.
