Launcher Logic (Checking and Releasing a Batch)

The Launcher is the starting point of our process. Cards wait here until a sufficient batch size is reached. If the Launcher contains a number of cards equal to or greater than the defined loop batch size, they are released to the first production line's queue. Let's build this logic.

Create a new flow named Launcher Logic.

Step 1: The Start Node We need to tell the process which loop to check.

• Add an Input Variable: KANBAN_LOOP_ID (Type: Number).

Step 2: Count Cards and Load Loop Details We need two pieces of data: the current card count and the target batch size.

• Add a Load Object node named Number Of Cards In Launcher. Select the KANBAN_CARDS_VIEW, check Count records, and filter where KANBAN_LOOP_ID Equals your Start variable and LAST_LOCATION Equals Launcher.

• Add another Load Object node named Load Loop. Select the KANBAN_LOOP entity to get the Batch_Size property. Filter by ID and set the Limit to Single record.

Step 3: Evaluate Batch Size (If Node)

• Add an If node named Launcher Ready.

• Condition: We want to check if the batch requirement is met. Use the expression: {{datastore.process.LoadLoop.Batch_Size}} <= {{datastore.process.NumberOfCardsInLauncher}}.

• False Branch: If the condition is false, connect this to an End node. The batch is not ready, so the process stops here.

Step 4: The True Branch (Release Cards) If the batch is ready, we assign the cards to the first line.

• Connect the True branch to a new Load Object node named Cards In Launcher. Load from KANBAN_CARDS_VIEW using the exact same filters as Step 2, but set the Limit to match the batch size: {{datastore.process.LoadLoop.Batch_Size}}. This ensures we only release the correct number of cards.

• Add a Loop node named Release From Launcher (Type: Foreach) and iterate over the data from the Cards In Launcher node.

Step 5: Move to First Line (Inside the Loop) For every card in the loop, we create a new location and update its status.

• Add a Create Object node named Create New Location. Entity: KANBAN_CARD_LOCATION. Set Id_kanban_card to item.card_id and Id_production_line to item.loop_min_position_line_id (our custom view already calculated the first line for us!).

• Add an Update Object node named Update Card Status. Entity: KANBAN_CARD. Filter by id Equals item.card_id and update the id_status field to represent your active production status.

• Close the loop and connect it to an End node.
