on the toolbar to run this process.Use this screen to perform three functions, depending on which check box you select: Update Low Level Code, Check for Looping Parts, or Change Selected Parts from No Planning Option to MRP Planned. You can also specify a range of parts and revisions you want the process run against.
Use this screen when initializing MRP for the first time (after loading manufacturing bills of material), or if there is reason to believe that there could be a looping part in the bill of material. You can also use this function to modify planning type codes (to MRP Planned) for all parts that have no planning type code.
Click on the toolbar to run this process.
Use the fields in this block to create a new parameter ID or to retrieve a previously saved parameter ID. A parameter ID represents a set of screen selection parameters. After you have saved a parameter ID and its related parameters, you can retrieve them using Query.
You can use the retrieved parameters to produce reports and run processes more efficiently and with greater consistency. The saved parameters are also useful and necessary when you want to run the process as part of a batch job. Many users save a unique set of parameters for each different way they run a report or process. When you select a previously saved parameter ID or parameter description, the associated saved screen selection parameters automatically display as selection defaults. The page setup and print options are also included in the saved parameter ID if there are any. You can change any of the associated selection defaults as necessary.
Enter, or click 
to select, a parameter
ID of up to 15 alphanumeric characters. Choose characters for your parameter
ID that help identify the type of selections you made in the screen, such
as PERIOD or QUARTERLY.
When you save your record, all the selections made in the screen are stored with the parameter ID. Later, you can retrieve the parameter using Query.
You can use the parameter to run the process more efficiently because you can select the parameter ID with its previously defined screen selections. After the default selections display in the screen, you can override the defaults.
Enter, or click to select, a parameter
description of up to 30 alphanumeric characters.
Use this group box to specify the range of low-level codes you want to update.
Use these fields to enter the starting and ending revision numbers for the parts you want to include in this update.
Use this drop-down list to select the range of parts you want to include in this update. Available options are:
All — Select this option to include all available records. The Start and End fields are disabled for this option.
One — Select this option to include only one record. You must enter that value in the Start field. The End field is disabled for this option.
Range — Select this option to include a contiguous range of records. You must enter the beginning value for the range in the Start field and the ending value of the range in the End field.
From Beginning — Select this option to include all the records from the beginning of the available records to a specific record in the range. You must enter the last value for the range in the End field. The Start field is disabled for this option.
To End — Select this option to include all the records from a specific record to the end of all the available records. You must enter the value from which the range should begin in the Start field. The End field is disabled for this option.
Use this field to enter, or use 
to select, the starting part number, as applicable.
Use the adjacent field to enter, or use to select, the starting part's revision number.
Use this field to enter, or use to select, the ending part number, as applicable.
use the adjacent field to enter, or use to select, the ending part's revision number.
Use this group box to specify additional options for this screen.
Select this check box to update the low-level codes for the selected range of parts.
When you select this check box, the system first updates the low-level code of parts within the selected range. The low-level code is used to determine the processing order of parts when performing an MRP run. Updates to low-level code also occur within the Manufacturing BOM maintenance programs and MRP itself, but this process is a comprehensive update of these codes.
Select this check box to check Manufacturing Bills of Material for looping part numbers.
When you select this check box, the process looks for looping Manufacturing Bills of Material (that is, where a part exists as a parent to itself somewhere in its multilevel BOM). If such is found, the part and its where-used information will be listed in an exception report.
Select this check box to update parts with a Plan Type of None to a Plan Type of MRP.
When you select this check box, all the parts within the selected range with a Planning Type currently equal to N (None) are changed to P (MRP).
