The parameter settings that control backflushing are explained
using an example. The following items have been defined :
CLOCK
PIN
The PIN item is used as
a component for the CLOCK item in a task called ASSEMBLE.
Backflushing materials
Use the following settings in the Item - Production (tiipd0101m000) session to set up the items for
backflushing:
Select the Backflush if Material check box for the PIN item.
Select the Backflush Materials check box for the CLOCK item.
When you create a production order, these check boxes
determine the default settings of:
The Backflush Materials check box in the Estimated Materials (ticst0101m000) session (for PIN).
The Backflush Materials check box in the Production Order (tisfc0101s000) session.
You can modify these
check boxes for a particular production order. LN backflushes the
material only if you select both of these check boxes.
If you clear the Backflush Materials check box, LN clears the Backflush Materials check boxes for all materials.
Backflushing hours
Use the following settings to set up the items for
backflushing of hours:
Select the Backflushing check
box for the ASSEMBLE task in the Task Relationships (tirou0104m000) session.
Select the Backflush Hours check box for the CLOCK item in the Item - Production (tiipd0101m000) session.
When you define an operation for the ASSEMBLE
task, the Backflushing check
box in the Task Relationships (tirou0104m000) session determines the default setting
of the Backflushing check
box in the Routing Operations (tirou1102m000) session.
When you create a production order, LN sets the defaults as
follows:
The Backflushing check
box in the Routing Operations (tirou1102m000) session determines the default setting of
the Backflush Hours check
box in the Production Planning (tisfc0110m000) session.
The Backflush Hours check box in the Item - Production (tiipd0101m000) session determines the default setting of the Backflush Hours check box in the Production Order (tisfc0101s000) session.
You can modify these
check boxes for a particular production order. LN backflushes the hours
only if you select both of these check boxes.
If you clear the Backflush Hours check box, LN clears the Backflush Hours check
boxes for all operations.
To make backflushing of hours possible, you must also:
Enter a value in the Backflush Employee field in the Work Centers (tirou0101m000) session.
Enter a value in the Labor Type field in the Production Order Parameters (tisfc0100s000) session to determine whether
work is charged as normal hours or overtime hours.
Serialized items
Serialized items can only be backflushed if in the Items - Warehousing (whwmd4500m000) details session the Serials in Inventory check box is cleared, and the Register Lot Issue During As Built field in the Item - Warehousing (whwmd4600m000) session is Yes. In all
other cases, serialized items cannot be backflushed.
If the serialized item is lot-controlled, the lot from which
the items are backflushed is based on the outbound method ( Last In First Out (LIFO), First In First Out (FIFO)) as is defined in the Items - Warehousing (whwmd4500m000) details session.
Backflushing in Job Shop
Set the following parameters in the Production Order Parameters (tisfc0100s000) session:
Select a
backflushing method to determine the level of user interaction in the
backflushing procedure.
Select the devices
for the backflushing materials and hours reports.
Backflushing in Repetitive Manufacturing
You can manage materials backflushing in the Repetitive Manufacturing Parameters (tirpt0100m000) session. Depending on the
selected backflushing method, backflushing is triggered after
quantities end item are reported completed, when a shift is reported completed,
or one of the other triggers.
