  The SAP error message ME093 ("Please enter unique check sequence") typically occurs in the context of purchasing documents, such as purchase orders or purchase requisitions, when the system detects that the sequence of checks (for example, for release strategies or approval processes) is not unique. This can happen when multiple release strategies are defined for the same criteria, leading to ambiguity in the approval process.
  Cause:

  Go to the configuration settings for release strategies in the SAP system (Transaction code: SPRO).
  Check the release strategy definitions to ensure that each strategy has unique criteria and does not overlap with others.
