Batch Recipe Logic Validation

Sepasoft MES Module Suite

Batch engine evaluates recipes from top down and left to right.

Batch Recipe Workflow Elements	Transition Required After	Supported After (elements valid after this one)	Notes
Start	No	Phase Unit Procedure Operation And Begin Or Begin	Start begins the workflow.
Phase	Yes	Phase Unit Procedure Operation And Begin Or Begin
Unit Procedure	No	Phase Unit Procedure Operation And Begin Or Begin
Operation	No	Phase Unit Procedure Operation And Begin Or Begin
And Begin	Yes	Phases Unit Procedure And_Begin	Should always resolve in an And End . Step required between And Begin and Or Begin.
And End	Yes	Phase Unit Procedure And Begin	A Transition. is required after And End.
Or Begin	Yes	Phases Unit Procedure And_Begin Or_Begin	At least 2 transitions immediately following are required to determine condition logic. Using directly after an And_End is not supported based on best practices. Using a No-Action Phase (between the two) accomplishes that scenario and is valid.
Or End	No	Terminator Phases Unit Procedure And_Begin	Not required with an Or_Begin
Terminator	No		Can be nested in a Unit Procedure

Loop-Back (also called loopback or looping)	Transitions are required before the loopback to determine when to loopback and when to exit. There must be an exit path.		Recipes cannot have loopbacks that cause infinite loops. See Loopbacks in Batch Procedure Recipes
