Shifting region tracking configuration
To configure a shifting region, the corresponding record in the PRT_REGION file should have:
tracking_type_id: SHIFTING
tran_region_id: region_id of the transition region of shifting region.
When a new shifting region is configured, on the subsequent startup PRT will create blank items automatically for all the locations. These blank items are only placeholders; they cannot be deleted, added, or moved by the user.
Important: While configuring item types, do not configure any as item_type_id, which is a GE Fanuc reserved word for item_type_ids of blank items for the Import/Export utilities.
Shifting region process behavior
Other process behavior regarding shifting regions includes:
Process |
Description |
PRT |
PRT never returns blank items when a request for an item list is made. It will return only the valid items, and the RegionLoc field in the item structure will contain the actual location of that item. |
GLB_VERIFY |
GLB_VERIFY checks that the number of occupied locations in a shifting region is equal to the region capacity. |
prt_ui |
prt_ui displays a blank row for each blank location in a shifting region. A user cannot modify, delete, or move items at these locations. |
PRT_EXPORT/ |
While exporting a shifting region, prt_export generates one record for every blank location (even if the location can contain multiple items). This record contains the location number and the item_type_id as $$GEF@BLK@ITM$$. On import of these records with the reserved item_type_ids, prt_import generates blank item(s) at those locations. |
PRTCNT |
If: |
|
The prt_att_pt file is configured to display n to n+m items in a region and Any of the locations in that range is blank, Then no data is displayed for that location. |
|
If: |
|
The prt_att_pt file is configured to display the last n items in a shifting region and The number of valid items are equal to or greater than n. Then the last n valid items will be displayed. The prt_att_pt file is configured to display the last n items in a shifting region and The number of valid items are is less than n. Then those items will be displayed and the remaining locations will display blanks. |
